International observation | It is extremely irresponsible for Japan to approve the discharge of nuclear polluted water into the sea.

  Xinhua News Agency, Tokyo, July 23rd Japan’s nuclear regulatory agency, the Atomic Energy Regulatory Commission, held a meeting on the 22nd, officially approving the plan of Tokyo Electric Power Company (hereinafter referred to as TEPCO) to discharge nuclear polluted water into the sea at the Fukushima Daiichi nuclear power plant. According to this plan, TEPCO will start to discharge nuclear polluted water next spring if the local government agrees again.

  Analysts pointed out that in April last year, the Japanese government officially decided to discharge nuclear polluted water into the Pacific Ocean despite strong opposition at home and abroad. Over the past year or so, despite the rising opposition at home and abroad, the Japanese side turned a deaf ear and pushed forward the discharge of nuclear polluted water into the sea, which is extremely irresponsible and will cause serious harm to the global marine environment.

  Push hard

  In April this year, Japan Atomic Energy Regulatory Commission ignored domestic and international objections and doubts, and "generally agreed" to TEPCO’s emission plan, forming a draft "review book". After confirming the draft of the "review book" in May, the Committee said that the draft was "no problem" and entered the public consultation session.

  According to reports, 670 of the more than 1,200 opinions collected publicly are technical opinions, including concerns about the determination of the concentration of nuclear contaminated water and the earthquake resistance of equipment. Despite this, after discussing the opinions collected on the 22nd, the Atomic Energy Regulatory Commission said that TEPCO’s response was "appropriate" and approved its plan to discharge nuclear polluted water into the sea.

  After the Fukushima nuclear accident in March, 2011, a large amount of nuclear polluted water was produced to continuously cool the nuclear reactor whose core melted. TEPCO has prepared about 1,000 water storage tanks for storing nuclear contaminated water at the Fukushima Daiichi nuclear power plant. With the available capacity of water storage tanks getting less and less, the Japanese government held a cabinet meeting in April last year and formally decided to filter and dilute these nuclear polluted water and discharge it into the sea.

  Analysts pointed out that although the emission plan was nominally formulated by TEPCO, in fact, it could not be completed without the participation and support of the Japanese government.

  According to Japanese media reports, in addition to promoting the approval of emission plans, Japan is also stepping up the construction of sea-discharge pipelines. At the end of April this year, TEPCO started the construction of the outlet of the submarine tunnel for discharging nuclear polluted water, with the goal of completing related projects in April 2023.

  make irresponsible remarks

  At present, all parties are generally concerned about the impact of Japan’s discharge of nuclear polluted water on the marine environment and people’s health in countries along the Pacific Ocean. At the same time, questions are raised about the legitimacy of the nuclear polluted water discharge scheme, the reliability of Japanese data, the effectiveness of purification devices and the controllability of environmental impact. Grossi, Director General of the International Atomic Energy Agency, pointed out in an interview last year that Japanese nuclear waste water discharged into the Pacific Ocean should not cause environmental damage.

  The International Atomic Energy Agency set up a technical working group to visit and evaluate Japan twice. So far, it has not reached a conclusive opinion on Japan’s sea discharge plan, and at the same time, it has put forward many clarification requirements and improvement opinions. China and Russia submitted a joint technical questionnaire to the Japanese side, and they still haven’t received feedback from the Japanese side. Not long ago, the leaders’ meeting and foreign ministers’ meeting of the Pacific Island Forum also expressed serious concern about related issues.

  In this regard, the Japanese side not only deliberately avoided these questions, but also made irresponsible remarks and tried to cover up the harm. The Japanese side claimed that before the Fukushima nuclear polluted water was discharged into the sea, it had to be filtered by "Multi-nuclide Removal Equipment" (ALPS) to remove more than 60 radioactive substances. Tritium, which is difficult to be removed by the equipment, will be diluted to a concentration far lower than the Japanese national standard and discharged into the sea. The Japanese side also confuses the concept and confuses nuclear polluted water with waste water, saying that waste water discharged from nuclear power plants all over the world contains tritium, and it is safe to dilute it and discharge it into the sea.

  In fact, Fukushima nuclear contaminated water is not tritium-containing wastewater discharged during the normal operation of nuclear power plants, and the radioactive substances contained in it are extremely complex, so it is doubtful whether it can be effectively removed. Given that the Japanese government and TEPCO have many dishonest records in dealing with the Fukushima nuclear accident, their statements are unconvincing.

  Japanese media have found out that there are many radioactive substances in Fukushima nuclear polluted water beyond the standard except tritium. TEPCO also admitted that more than 70% of the nuclear polluted water treated by ALPS does not meet the discharge standards and needs to be filtered again.

  strongly oppose

  There have been a lot of doubts and objections in Japan and the international community about Japan’s plan to discharge nuclear polluted water into the sea. The statement made by the Japan Atomic Energy Regulatory Commission on the 22nd once again aroused serious concern, and all parties urged Japan to cancel the wrong decision to discharge nuclear polluted water into the sea.

  People from Tokyo, Chiba and Fukushima held protests that day. The people who participated in the event said that the decision of the Atomic Energy Regulatory Commission is related to the future of Fukushima and the marine environment, but it is very irresponsible to make such an important decision without fully informing the Japanese people. Some people also said that they are resolutely opposed to discharging nuclear polluted water into the sea, and Japan can no longer pollute the ocean and pollute the earth.

  The National Federation of Fishery Associations of Japan held a meeting in Tokyo a few days ago and unanimously adopted a special resolution of "reaffirming the position of resolutely opposing the discharge of nuclear polluted water from Fukushima into the sea". This is the third time that the group has passed a resolution against the discharge of Fukushima nuclear polluted water into the sea.

  Japan’s irresponsible behavior triggered strong opposition from neighboring countries. The South Korean government said on the 22nd that it was worried about the Japanese nuclear regulatory agency’s approval of discharging pollutants into the sea, and it would take countermeasures. At the same time, South Korea will also strengthen cooperation with the International Atomic Energy Agency and strengthen the detection of domestic marine environmental radiation.

  China’s Ministry of Foreign Affairs reiterated on the 22nd that the disposal of nuclear polluted water in Fukushima is related to the global marine environment and the public health of Pacific Rim countries, and is by no means a private matter of Japan. China once again urges Japan to earnestly fulfill its due international obligations, dispose of nuclear polluted water in a scientific, open, transparent and safe way, and stop pushing the plan of discharging the sea. The Ministry of Foreign Affairs of China emphasizes that before full consultation and agreement are reached with stakeholders and relevant international institutions, shall not start the discharge of nuclear polluted water into the sea without authorization. If Japan insists on putting its own self-interest above the international public interest and taking a dangerous step, it will pay the price for its irresponsible behavior and leave a historical stain.

It is not difficult to see Hengda’s dedication to new energy vehicles. And Hengchi 5 did not disappoint everyone, whether it is the appearance, or the performance of the interior is not bad, as well as the same level of leading intelligent configuration, strong power and 179,000 yuan price, so that Hengchi 5 in the same class of models has a very good cost performance, plus 15 days after the car can be returned and refunded, 3 years 60% off repurchase, vehicle lifetime quality assurance, three electric lifetime quality assurance and other car purchase policies, but also once again push up Hengchi 5 cost performance, so for such a cost-effective vehicle will be excited?

[CCTV quick review] solidly promote the high-quality development of the Yangtze River Economic Belt

  The long Yangtze River water rushes into a new era. In July 2013, General Secretary of the Supreme Leader visited Yangluo Container Port Area of Wuhan Xingang in the rain, stressing that the Yangtze River basin should strengthen cooperation, give full play to the role of inland river shipping, develop river-sea combined transport, and turn the whole basin into a golden waterway.

The Yangtze River shows a new atmosphere.

  Striving for a new journey, the Yangtze River Economic Belt is playing an extremely important role in Chinese modernization. The Yangtze River Economic Belt covers 11 provinces and cities along the Yangtze River, spanning the three major sectors of China’s east, west and east. Its population size and economic aggregate account for half of the country’s total, with outstanding ecological status and great development potential. The Yangtze River has created a thousand-year cultural context from Bashan Shushui to Jiangnan Water Town, and cultivated Chinese civilization. From a strategic and long-term perspective, we should deeply understand the great significance of the Yangtze River to the construction of a strong country and national rejuvenation, and strive to make the Yangtze River Economic Belt the main battlefield for China’s ecological priority and green development, unblock the domestic and international double-circulation aorta, and lead the main force for high-quality economic development.

What changes will happen in medical education in the future?

  The General Office of the State Council issued the Guiding Opinions on Accelerating the Innovation and Development of Medical Education (hereinafter referred to as "Opinions") on the 23rd, and made systematic arrangements from the aspects of comprehensively optimizing the training structure of medical talents, fully improving the quality of medical talents training in colleges and universities, deepening the reform of resident training and continuing medical education, and improving safeguard measures.

  According to the Opinions, by 2025, the discipline structure of medical education will be more optimized, and the management system and mechanism will be more scientific and efficient; A high-level medical personnel training system has been basically established, and the quality of training has been further improved. The incentive mechanism for the use of medical talents is more perfect. By 2030, a higher-level medical personnel training system with China characteristics will be established, and the ability of medical scientific research and innovation will be significantly improved, and the ability to serve the health cause will be significantly enhanced.

  What changes will take place in medical education in the future? How to make medical education become an important cornerstone of the development of health care? In this regard, the reporter interviewed the relevant officials of the Ministry of Education, the National Health and Wellness Commission and state administration of traditional chinese medicine.

  Comprehensively optimize the training structure of medical talents

  Maintaining the health of hundreds of millions of people can not be separated from the skilled and sufficient medical staff. So, how to optimize the training structure of medical talents?

  According to the relevant person in charge of the Ministry of Education, there are still some structural problems in the training of medical talents, mainly in the fact that the overall enrollment scale of medical education is large, but the overall level is low, the shortage of general practitioners and high-level public health talents is obvious, and the training of high-level compound medical talents also needs to be strengthened.

  The "Opinions" put forward that the level of medical professional education should be improved, higher vocational nursing education should be vigorously developed, undergraduate clinical medicine and traditional Chinese medicine education should be steadily developed, and the enrollment scale of graduate students should be appropriately expanded. Efforts will be made to strengthen the construction of medical disciplines, increase the layout and support of medical and related disciplines, optimize the professional structure of disciplines, and vigorously promote the construction of disciplines such as anesthesia, infection, severe illness and pediatrics and the training of professional talents. Strengthen the training of general practitioners, gradually expand the scale of training free general practitioners who serve the grassroots, and train a number of higher vocational directional medical students for village clinics and township hospitals in remote and poor areas in light of the actual situation, and accelerate the training of general practitioners who combine prevention with treatment.

  At the same time, we will systematically plan the teaching system of general practice, strengthen the general practice education for all medical students, and build about 100 national demonstration bases for general practice teaching. Accelerate the reform of the general practitioner’s salary system and expand the career development prospects of general practitioners. In addition, it is necessary to speed up the construction of high-level public health personnel training system and high-level compound medical personnel training, build a number of high-level public health colleges, take the master’s degree training plan of public health as the main training plan of public health postgraduate education, create and develop public health doctoral degree education, and increase the supply of high-level professional personnel.

  Improve the quality of medical education personnel training

  Quality is the lifeline of medical education. According to the relevant person in charge of the Ministry of Education, medical education in colleges and universities is an important foundation for the three-stage continuum of medical personnel training. One of the key tasks of this reform and innovation is to comprehensively improve the quality of medical personnel training in colleges and universities.

  "First of all, it is necessary to improve the quality of imported students, build a number of first-class medical schools based on high-level universities, expand the enrollment scale of undergraduate medical majors in institutions affiliated to the central department, and increase support for medical education in the’ Strong Foundation Plan’. Cultivate benevolent medical talents and build about 600 first-class professional construction points for medical undergraduates. Strengthen the construction of grassroots teaching organizations such as teaching and research sections, strengthen the training of nursing professionals, and enhance students’ critical thinking and clinical practice ability. " The person in charge said. At the same time, the "Opinions" proposes to inherit and innovate the development of Chinese medicine education, concentrate superior resources to make the main specialty of Chinese medicine bigger and stronger, carry out the nine-year education of integrated traditional Chinese and western medicine on a pilot basis, and cultivate fewer but better, high-level and high-level talents of integrated traditional Chinese and western medicine. Consolidate the main position of medical personnel training in affiliated hospitals of colleges and universities, and strive to promote early clinical, multi-clinical and repeated clinical practice for medical students.

  In addition, it is necessary to establish and improve the quality evaluation and certification system of medical education. Accelerate the professional accreditation of medical education, build a medical education accreditation system with full coverage of medical majors, and establish a medical education accreditation system with China characteristics and international substantive equivalence.

  Deepen the training of residents and ensure that medical staff receive continuing medical education.

  "In terms of ensuring the reasonable treatment of residents, first, the residential training base is required to formulate standards for the payment of salaries and benefits for trainees, and tilt to the shortage of majors such as general practice and pediatrics. Second, the residential training base will sign a labor contract with the training target recruited by the society according to law, clarifying the rights and obligations of both parties. After the labor contract expires, it will be terminated according to law, and the training target will choose their own jobs. Third, graduates of ordinary colleges and universities who are recruited for the society and are qualified to live and train in medical and health institutions in the same year are treated equally in terms of recruitment, dispatch and settlement. Fourth, clinicians with bachelor’s degrees who have passed the residence and training are treated equally with graduate students majoring in clinical medicine and traditional Chinese medicine in terms of personnel recruitment, professional title promotion and remuneration. " The relevant person in charge of the National Health and Wellness Commission said.

  "In view of the shortcomings of medical staff’s knowledge and skills exposed by the COVID-19 epidemic, on the basis of emphasizing the knowledge of medical ethics, laws and regulations as compulsory courses in the past, it is further clearly required to make public health knowledge and skills such as emergency and severe rescue, infection and self-protection, prevention and control of infectious diseases, health education as compulsory courses for medical staff. At the same time, the situation of medical staff receiving continuing medical education is included in the necessary content of their annual performance appraisal. " The person in charge also said that in terms of funding guarantee, employers are required to increase investment, extract and use employee education funds according to laws and regulations, and ensure that all on-the-job medical personnel receive continuing medical education and vocational retraining.

  Ensure that the innovation, development and reform measures of medical education are implemented

  The innovation and development of medical education is a complex systematic project, which needs the coordinated promotion of education, health, development and reform, finance, human society and other departments.

  Therefore, the Opinions put forward specific safeguard measures from three aspects. The first is to strengthen organizational leadership. Relevant departments should further strengthen the comprehensive management and overall planning of medical education, and coordinate and solve problems related to the innovation and development of medical education. All localities and relevant departments should incorporate the innovative development of medical education into the local economic and social development plan and the key work plan of the department.

  The second is to implement major national strategic projects. Co-ordinate the financial resources of all parties, strengthen the investment guarantee for medical education, support the construction of national and regional medical education development bases, first-class medical schools, high-level public health colleges, basic medical research and innovation bases, national resident training demonstration bases, and continuing medical education informationization, and increase the support for medical colleges from the central budget.

  The third is to ensure the investment of funds. Actively support the innovative development of medical education, reasonably determine and timely adjust the standard of per capita fixed funding and housing and training subsidies for medical majors according to financial resources, price changes and training costs, and local people’s governments at all levels shall implement their investment responsibilities in accordance with regulations.

"Mutual protection" is on fire! The maximum insurance is 300 thousand. Can it replace the critical illness insurance?

  BEIJING, Oct. 22 (Zhang Xu) Recently, "mutual insurance" has caught on fire, with more than 3.3 million fans in just three days, but many people may not really understand "mutual insurance".

  Many netizens are curious, "Usually 1 cent, serious illness becomes 300,000?" So, what kind of insurance does mutual insurance belong to? What’s the difference with the mutual help platform on the Internet? Can you replace critical illness insurance?

  What is "mutual insurance"?

  Recently, Ant Insurance and Xinmei launched "mutual insurance" with each other: 0 yuan, an ant member (under 60 years old) with sesame score of 650 or above, joined, and paid a certain amount every month, and could enjoy 100,000 or 300,000 security funds covering 100 kinds of serious diseases.

  "Mutual insurance" actually belongs to a kind of mutual insurance. At present, there are only three mutual insurance agencies in China, and Xinmei Mutual is one of them.

  For most people in China, mutual insurance is a new thing. In fact, mutual insurance has a mature practice and wide application in the world, and it is not only used to protect serious illness.

  "For example, in Japan, mutual insurance accounts for 80% of its insurance industry." Wang Xujin, director of the Insurance Research Center of Beijing Technology and Business University, told the reporter, "The biggest difference from joint-stock insurance is that the applicant and beneficiary are the same, which avoids moral hazard."

  For example, joining "mutual insurance" means joining a mutual aid organization, sharing the expenses at ordinary times and getting protection when necessary.

  After the insured person is diagnosed with the disease, he only needs to take photos with his mobile phone and upload relevant vouchers, and he can get the security money at one time without objection, with the amount of 100,000 or 300,000. If you don’t want to share it halfway, you can quit at any time, and you can join at any time after quitting.

  Fang Yong, the person in charge of "mutual insurance" products, said that general insurance products will be priced according to the incidence of diseases, and users need to pay fixed premiums first. The user 0 yuan joins the "mutual insurance", and the subsequent expenses will be shared according to each payment case. If you have it, you will be exempted, and the threshold is very low.

  To give a simple example, if 100 people join the "mutual insurance", one person is seriously ill, and the treatment fee exceeds 300,000 yuan, which will be shared among everyone, and everyone will have to pay 3,000 yuan each in the current period. If no one is sick, then there is no need to pay.

  Will there be no limit to the monthly payment?

  Although the threshold for 0 yuan’s participation in "mutual insurance" is very low, based on the principle mentioned above, some people are worried that there will be more and more money to be paid for subsequent sharing, and there is no upper limit.

  In reality, the possibility of this situation is very low.

  Ceng Zhuo, chief actuary of Xinmei Mutual, told the reporter that in fact, the probability of serious illness is not high. According to his estimation, the user’s share of expenses in the first year may be between 100-100 200 yuan.

  As of the afternoon of the 19th, there were more than 3.3 million "mutual insurance" users. Some netizens are concerned that "mutual insurance" is shared according to the actual monthly claim amount. Can it cost less to join when 100 million people join the insurance?

  In this regard, some people in the insurance industry told reporters: "Statistically, when there are enough samples, the ratio of the number of patients to the total number of participants will remain stable, so after the number of participants exceeds a certain number, the amount shared by each person will not change greatly."

  Can mutual insurance replace the traditional critical illness insurance?

  Some netizens said: The sharing price of "mutual insurance" is much lower than that of critical illness insurance. Can it replace critical illness insurance?

  Yin Ming, president of Ant Financial Insurance Group, clearly replied that "mutual insurance" cannot replace the existing critical illness insurance.

  First, the amount of "mutual insurance" is not high enough. The amount of protection under 39 is 300,000, and the amount of protection between 40 and 59 is 100,000. In reality, the medical cost of patients and families with major diseases is much higher than this amount.

  The "2017 Claims Report" issued by Luen Thai Metropolitan Life Insurance Co., Ltd. shows that in 2017, the per capita compensation for major diseases was about 200,000 yuan. With the use of targeted therapy and other means, the cost of 400,000-500,000 yuan has become common.

  Second, the guarantee period of "mutual insurance" is not long enough. "Mutual insurance" will automatically quit after the age of 60, and the data of "Experience Incidence Table of Major Diseases in China Life Insurance Industry (2006-2010)" shows that the incidence of major diseases is increasing with age. Mutual protection does not work when it is most needed.

  Therefore, "mutual insurance" is more as an aid to critical illness insurance, which can benefit more groups lacking commercial health protection.

  What’s the difference between it and a mutual help platform?

  Helping each other is a prominent feature of mutual protection. There have been similar mutual aid platforms on the Internet before, such as "Water Drop Mutual Assistance" and "Quark Alliance".

  However, there are fundamental differences between the two, and many online mutual aid platforms belong to mutual help communities. "And ‘ Mutual insurance ’ It is an insurance product that has been filed with China Banking and Insurance Regulatory Commission. " Ceng Zhuo said that "mutual insurance" is a one-time full rigid payment, which is also different from "how much you receive and how much you pay" for network mutual assistance.

  Ceng Zhuo said that in addition to information disclosure in accordance with laws and regulations, "mutual insurance" also introduced two major measures: first, set up a publicity system and accept the supervision of all members; The second is to introduce blockchain technology to ensure that information cannot be tampered with. In addition, the personal information of the publicized person will also be kept strictly confidential.

  In other words, "mutual insurance" is an insurance product with controllable risks, while "water drop mutual assistance" and "quark alliance" are not insurance and are not subject to financial supervision. (End)

[How to play in Shennongjia in winter] Meet the fairy golden monkeys in Shennongjia and watch them have fun in the snow!

Encounter golden monkey

Walking into the field research base of golden monkey in Dalongtan, the snow is covered, and the warm sunshine shines through the treetops to the snow, which makes the golden monkey group particularly energetic. You will find yourself in the golden monkey kingdom, where smart golden monkeys are either hidden in Shan Ye or active in the Woods. They are the most interesting stars in Shennongjia tourist attractions.

In Shan Ye, the awakened golden monkey, alive and kicking in the rime and ice hanging, swims and frolics in succession, which is full of interest. Golden monkeys are in groups of three or five, combing each other’s golden hair and enjoying sunbathing in the snow leisurely.

After eating, the golden monkey jumps and fights on the branches, or the family hugs to resist the cold, or the husband and wife love each other and care for their hair, or wrestle and wrestle in the snow, bringing beautiful vitality to the ice and snow world. This scene always attracts many tourists to stop and watch, linger and forget to return, and attracts many photographers every year.

Shennongjia golden monkey is a unique primate species in China, which is an endangered and rare animal under national first-class protection. Shennongjia, the roof of Central China, has a unique geographical environment and climate, which is very suitable for the survival of golden monkeys. Their faces are sky-blue, their nostrils are upturned, their mouths are big and prominent, their tails are almost the same length as their bodies, and they have soft golden hair, which is as bright as silk, agile and cute!

The winter in Shennongjia is particularly long, and there is not much food for golden monkeys. Therefore, in autumn and winter, Shennongjia forest area adopts artificial food replenishment to protect golden monkeys from extreme weather stress.

Come and meet the golden monkey in Shennongjia!

Monograph on "Studying Military Affairs, Studying War and Studying War" How to Grasp the Brand-new Characteristics of Unmanned Combat

Grasp the brand-new characteristics of unmanned combat

■ Zhou Qingfeng

introduction

Unmanned combat is a combat form with artificial intelligence technology as the core and unmanned combat system as the main force. In recent years, unmanned combat system has penetrated into many links of war, and its combat effectiveness has become increasingly prominent, and combat forms are common. With the unmanned combat system being widely used in the battlefield, unmanned combat is showing brand-new characteristics.

All-weather multifunctional global operations

The advantage of unmanned combat system is that it is unmanned, and its combat state will not be affected by factors such as energy, physical strength and emotion, so unmanned combat system has the adaptability to any battlefield environment and combat space. No matter in extreme weather such as extreme cold, extreme heat, high pressure and lack of oxygen, or in the environment where human beings are difficult to survive, such as nuclear radiation and biochemical attacks, the unmanned combat system can still perform the established program tasks. Therefore, the ability of unmanned combat system to perform tasks in all time and space can effectively meet the needs of future wars, thus increasing the winning weight. Thanks to the development of artificial intelligence technology, the autonomous route planning and target recognition capabilities of unmanned combat vehicles have advanced by leaps and bounds, and with its powerful firepower, the combat attack power of bicycles can even be comparable to that of a squad. In addition to combat assault, unmanned combat vehicles can also rescue and transport the wounded in the rain of bullets. Logistics-assisted unmanned combat vehicles can greatly improve the mobility and sustained combat capability of troops. The UAV can stay in the target airspace for reconnaissance for a long time, keep tracking and monitoring the predetermined target for a long time, and can rely on the highly information-based combat system to send back the operational information, accurately strike the target according to the corresponding instructions, and conduct target damage assessment to avoid high-cost fire coverage and manned fighter dispatch. Unmanned submersible has long been famous, whether it is an attack platform with weapons or a reconnaissance platform without weapons, it is the natural enemy of surface ships and submarines. A complete unmanned cluster can even "take over"From mine clearance and explosive disposal, reconnaissance and surveillance, alert search to coordinated attack and defense, autonomous operations, material transportation support and other fields, it has great operational potential, thus opening a new era of unmanned intelligent operations.

Real-time accurate and transparent battlefield situation awareness

Battlefield perception system plays an important role similar to "eyes and ears" in the combat system, and the attack and protection of hostile parties against battlefield perception system has become one of the important tasks of modern warfare. With the qualitative leap of information technology, especially the technical performance of sensing equipment based on sensing technology, the resolution and detection distance of various sensors in unmanned combat system have been greatly improved, which not only has the ability to perceive the battlefield environment independently, but also has the efficiency beyond human perception. At the same time, these unmanned platforms with sensors have the ability of autonomous identification and resolution, which can help commanders quickly locate, identify targets and judge their threat. Unmanned intelligence, reconnaissance and surveillance systems with sensors as the core are all over the battlefield, forming a three-dimensional reconnaissance and surveillance system that complements each other in space, time domain and frequency domain, which can accurately detect almost all situations on the battlefield, and organically connect scattered sensors through high-speed broadband networks, so that any platform placed in the network can share information with the whole combat system as long as it obtains it. Unmanned reconnaissance and early warning equipment can give full play to the advantages of anti-electronic interference, flexibility, nuclear radiation resistance and strong concealment, thus greatly improving the battlefield perception. Because all unmanned platforms have the sensor function, they can obtain target information from all directions through distributed detection in cluster operations, and realize rapid and synchronous sensing of unmanned clusters through intra-group sharing and intelligent processing and distribution.

Intelligent, convenient and flat operational command and control

In the future war, unmanned combat systems such as unmanned aerial vehicles (UAVs), unmanned vehicles and unmanned ships will be widely used, which will lead to major changes in operational command system, command mode and command scene. First of all, the command system has evolved into a flat network, and the traditional multi-level command chain may be compressed into a "commander-cluster" two-level command chain. The management scope of the command organ has gradually widened, and the organizational structure has developed into a flat, horizontally connected and vertically integrated network structure. Secondly, the command mode has changed to intelligent autonomy. With the expansion and application of unmanned combat system, the corresponding new operational command mode will gradually take shape. In the primary stage, the command mode is "man in the loop", and the unmanned combat system is in a supporting role. The command mode in the intermediate stage is supervised "people on the loop". In the advanced stage, the intelligent decision-making system is mature, and the rules and tactics of engagement have been preset in the autonomous control software of the unmanned combat system. The unmanned cluster can independently perceive, judge, make decisions and act, and command itself without human intervention. The command mode presents a completely autonomous operation, that is, "people are outside the loop". Because of the high intelligence of unmanned combat system, it has the ability of independent decision-making with little or no participation of personnel, and can independently complete the spike cycle from target positioning and task assignment to attack and evaluation of combat process, thus improving the speed from discovery to attack.

Invisible, silent and sudden comprehensive precision strike

"Take it by surprise" has always been the rule of winning a war. The unmanned combat system, using stealth design, stealth materials, micro-size, through stealth, hiding, interference, orbit change, acceleration and other technologies, reduces the external characteristics of the unmanned combat system to the minimum, making it difficult for opponents to find, avoid and resist attacks, thus making it necessary to cooperate with various objective conditions to achieve suddenness in the past, and transforming it into using technical means to achieve suddenness at any time and anywhere. For example, the flying height of a small UAV can be reduced to 40 meters, which is as small as a bird and can effectively avoid the radar of the other side. Unmanned submersibles and unmanned combat vehicles can also be designed to be streamlined with flatter shapes and narrower cross sections, and a large number of new stealth technologies are adopted to effectively reduce the reflection cross section. When the unmanned combat system carries out sneak attack, it can make the other side fall into a situation of being unpredictable and passive. Therefore, the invisible and silent unmanned combat platform has an inherent advantage in future combat competition. Using the characteristics of unmanned combat system, such as silent and invisible action, accurate and efficient attack, we can carry out acupuncture and disability operations to accurately attack key parts. The key is to use all kinds of disability means in combination, including influencing and controlling people’s thoughts, consciousness or infecting artificial intelligence to lose computing ability to control the brain; Confuse people’s visual organs, destroy the sensor system, and achieve the purpose of blindness; Restrict or destroy the mobility of people’s actions and equipment to achieve the purpose of braking. The unmanned combat system enables precision strikes to achieve their operational goals invisibly and silently.

Cooperate with efficient and omni-directional bee colony to fight.

"Bee colony" is a collection of a large number of intelligent unmanned platforms with different functions, which has a unique application mode that a single weapon system does not have. Taking advantage of the synergy and quantity advantages of "bee colony operation", omni-directional penetration, distributed killing and cluster protection can be implemented. Collaborative advantage, that is, through group intelligent decision-making and online task decomposition and assignment, each platform in the group can dynamically and independently cooperate and self-adaptively cooperate. Quantitative advantage means establishing a dynamic self-healing "kill net" according to the actual battlefield, and carrying out multi-directional continuous or simultaneous saturated compound attacks on the target to achieve the effect of "small but many" over "big but few". Omni-directional penetration, that is, due to the low cost and large number of small unmanned platforms, multi-directional and three-dimensional simultaneous penetration can be carried out on a wide front, causing the enemy to disperse its defense forces because of the average use of troops, resulting in weak defense, thus achieving effective penetration. Distributed killing, that is, "bee colony" usually groups different functional platforms according to combat tasks, forming a comprehensive combat group integrating reconnaissance, electronic jamming, network attack and fire attack, which can simultaneously carry out omni-directional or continuous pulse multi-domain "soft and hard" compound attacks on the same high-value large target or regional group target from multi-dimensional space and multiple directions, which can not only meet the precise attack on point targets, but also ensure the comprehensive coverage of opposite targets. Cluster protection, that is, "bee colony" can also build an intelligent adaptive defense system, forming an automatic response protection "bubble" around the main assault forces or important targets, forming a three-dimensional and multi-level interception network, which can not only "block more with more" but also "block more with more".With wide interception range and high success rate, it is an important way to cooperate with air defense and anti-missile operations, terminal protection of important targets and anti-enemy bee colony attacks in the future.

Joint service support with accurate and intelligent response

Unmanned system has the advantages of high self-awareness, long-term operation, high precision measurement and so on, which will make the future joint operational support action based on network information system more independent, intelligent, efficient and accurate, thus making the joint service support mode more accurate. Combat support is timely and efficient, with flexible unaccompanied support. The unmanned system can carry corresponding functional modules, adopt autonomous follow-up or remote control support, independently or assist traditional support forces, and carry out support tasks in a hidden, safe, fast and efficient manner. The joint service support needs to respond independently, and no one can deliver it directly and accurately. Relying on the "visual" support network system, unmanned support forces quickly assess the position of the support object and the change of the battlefield situation, avoid the enemy threat area, and plan a safe and fast route to the delivery position. Due to the unmanned platform and long battery life, the unmanned system can continuously provide timely, appropriate and appropriate accurate support in a dangerous environment, especially the terminal replenishment of ammunition, food, fuel and other materials and equipment for frontline combat troops, which can not only effectively solve the "last mile" problem of the support chain, but also greatly reduce the casualties of support personnel. During the war in Afghanistan, in order to avoid the threat of improvised explosive devices to ground transport vehicles, the U.S. military used K-MAX unmanned helicopters to supply materials to forward bases and marines stationed at outposts. This machine can fly directionally according to the GPS system, and can also be controlled by ground personnel through a remote control device, and materials can be hoisted or delivered with the assistance of personnel, and 2 tons of materials can be hoisted and transported each time.It can deliver about 13.6 tons every day. In addition, in underwater operations, large-scale underwater unmanned submersibles can also undertake the task of supplying materials in advance, which can not only provide equipment, supplies and other supplies for special operations teams or other offshore platforms that perform tasks secretly, but also transport, supplement or evacuate a small number of combatants.

Expanding domestic demand, stabilizing economy and protecting people’s livelihood

  editorial comment/note

  At present, the phased results of epidemic prevention and control in China have been further consolidated, important progress has been made in resuming work and production, and the economic and social operation order has been accelerated. At the same time, the international epidemic continued to spread, the downside risks of the world economy intensified, and the unstable and uncertain factors increased significantly. General Secretary of the Supreme Leader pointed out that in the face of the severe and complicated international epidemic and the world economic situation, we should adhere to the bottom line thinking and make ideological preparations and work preparations for coping with external environmental changes for a long time. Politburo meeting of the Chinese Communist Party, held on April 17th, made it clear that the strategy of expanding domestic demand should be firmly implemented to safeguard the overall situation of economic development and social stability. In order to further understand the important role of expanding domestic demand in coordinating epidemic prevention and control and economic and social development, the Economics edition specially invited three experts and scholars today to analyze the current macroeconomic situation and deeply interpret the strategy of expanding domestic demand.

  1. Fully grasp the total demand situation and accurately understand the significance of expanding domestic demand.

  Moderator: According to the economic data of the first quarter released by the National Bureau of Statistics, affected by the epidemic, although the economic growth rate of China in the first quarter decreased by 6.8% year-on-year, the decline of major economic indicators in March was obviously narrowed, and the pace of economic recovery was accelerated. Excuse me, how do you view the current macroeconomic situation in China?

  Liu Shijin:This economic downturn is due to an unexpected super external shock, rather than problems such as serious shortage of demand and excessive leverage in the economy. It is different from the financial or economic crisis. Under the external impact of the epidemic, economic recovery depends on two factors, one is the duration of the epidemic, and the other is the degree of production capacity damage. If the epidemic lasts for a short time and the production capacity is limited, a V-shaped rebound can occur after the epidemic; If the epidemic lasts for a long time, or the production capacity is seriously damaged, it is not so easy to rebound. Therefore, in addition to controlling the epidemic as soon as possible, the short-term policy focuses on minimizing the damage to production capacity and protecting productivity. Judging from the data in March, the signs of economic recovery are obvious.

  In this case, I think we should adopt the evaluation method of "relative growth rate" to examine China’s economic growth, that is, use the ratio or difference between China’s growth rate and the world average growth rate to evaluate China’s economic growth. The basic background of this method is that China’s economy has been integrated into the global economy to a great extent, and the impact of this epidemic is also global. Compared with the past, if this ratio or difference is stable or rising, it shows that China’s economic performance is good, and vice versa. For example, in 2019, the average growth rate of the world economy was 2.9%, that of China was 6.1%, and the relative growth rate was 3.2%; If the world’s growth rate is -2.5% and China’s is 3% in 2020, our absolute growth rate will decrease, but the relative growth rate will increase to 5.5%, then China’s economic performance will be excellent. In a word, we should treat the current economic development of China comprehensively and dialectically.

  Liu Yuanchun:The economic downturn caused by the epidemic is completely different from the general economic crisis and financial crisis. In epidemics such as infectious diseases, economic activities are almost completely at a standstill due to personnel isolation, and the complete industrial chain breaks into a single enterprise, and products, elements and funds cannot flow normally. Therefore, in a short period of time, the economic decline caused by the epidemic is often more severe than the economic recession caused by the financial crisis. But for the economy, the epidemic is a typical exogenous systemic shock, and the resulting economic downturn is also exogenous. For example, the decline caused by the epidemic is like an emergency in the economy, while the economic crisis is more like a chronic disease caused by bad living habits. Therefore, as long as the epidemic situation can be quickly controlled and the emergency can be quickly cured, the economy may achieve rapid recovery. On the whole, although China’s economy has been severely hit by the epidemic, the basic conditions and factors supporting the long-term improvement of the economy have not changed, the trend of industrial upgrading and rapid growth of new kinetic energy has not changed, and the economic and social operation order is accelerating recovery and continuing to improve.

  Moderator: Politburo meeting of the Chinese Communist Party, held on April 17th, made it clear that the strategy of expanding domestic demand should be firmly implemented and the expansion of domestic demand should be placed in a more important position. If we want to make a comprehensive analysis of total supply and total demand, what kind of total demand situation are we facing at present? What is the significance of putting forward the strategy of expanding domestic demand?

   Liu Yuanchun:According to the data of the first quarter and March, China suffered a severe total supply shock and total demand shock during the epidemic, but since March, the total demand has rebounded moderately. With the epidemic basically under control, the main macroeconomic contradiction is changing from a big impact on both supply and demand to a lack of total demand. In March, the resumption of work and production progressed smoothly, and the supply side started relatively quickly. Comparatively speaking, the recovery of demand side was relatively slow, and insufficient total demand was the main factor restricting the rapid economic recovery.

  Specifically, the impact on consumer demand is the most obvious, 1-mdash; In March, the total retail sales of social consumer goods decreased by 19.0% year-on-year, but the decline in March was 1-mdash; It narrowed by 4.7 percentage points in February; In terms of investment demand, the epidemic has led to a rapid decline in fixed assets investment in China, which is gradually recovering. Compared with the same period of last year, although the fixed assets investment in the three major industries has dropped significantly, the growth rate of fixed assets investment in pharmaceutical manufacturing and Internet companies is significantly higher than that of the whole society. During the epidemic, more advanced technologies were widely used and the industrial structure of fixed assets investment was further optimized. In terms of net export demand, the accumulated trade surplus in the first quarter decreased by 80.6% compared with the same period of last year, but the foreign trade import and export in March was 1-mdash; In February, there was a significant improvement from the previous month.

  The central government’s proposal to firmly implement the strategy of expanding domestic demand is conducive to maintaining the basic stability of total demand. Insufficient aggregate demand is the main problem facing the macro-economy at present, and the basic stability of aggregate demand is conducive to the stable development of macro-economy. At present, on the one hand, it is necessary for the whole industrial chain to resume production, on the other hand, it is necessary to prevent the second shutdown due to no orders and no demand after the resumption of production. In the current situation that foreign trade has not declined in an all-round way, there is a good window to boost domestic demand and prepare for shock prevention in advance, which must not be missed.

  At present, the epidemic is spreading around the world, and the global value chain is facing a severe risk of breakage. If this situation lasts for a long time and the external demand is insufficient for a long time, it will pose a threat to the integrity of China’s industrial chain. Expanding domestic demand is conducive to maintaining domestic production capacity, maintaining the integrity and smoothness of the domestic industrial chain and creating favorable conditions for rapid economic recovery. In addition, the strategy of expanding domestic demand can not only achieve the goal of macroeconomic stability, but also guarantee the basic livelihood of grassroots people in many ways, which is conducive to maintaining the basic stability of society.

  Han Baojiang:From the economic development history since China’s reform and opening up, the strategy of expanding domestic demand is an effective way to deal with the impact of the crisis. In 1997, in response to the impact of the Asian financial crisis on exports and utilization of foreign capital, the central government proposed "expanding domestic demand and strengthening infrastructure construction", which played an important role in minimizing the impact of the Asian financial crisis and achieving rapid and healthy economic development in China. After the outbreak of the international financial crisis in 2008, the central government made a strategic decision to deal with the impact of the crisis by expanding domestic demand, and launched a 4 trillion package of economic stimulus policies. China’s economy quickly realized a V-shaped rebound, which not only played an important role in completing the economic development goals at that time, but also made up for the shortcomings of economic and social development to a great extent by investing in infrastructure and ten strategic industries. At present, in response to the impact of the COVID-19 epidemic, the central government has made a strategic decision to expand domestic demand, not only to better hedge the external demand that has fallen sharply due to the spread of the epidemic in the world, but more importantly, to safeguard the safety of the domestic industrial chain and supply chain and to maximize the stable development of China’s real economy. By expanding investment demand, it is also conducive to speeding up the shortcomings of unbalanced and uncoordinated development and laying a solid foundation for future economic and social development.

  By expanding domestic demand and providing more demand space for the products or services produced by enterprises to achieve a "thrilling leap", more enterprises can survive and employment, finance and people’s livelihood can be guaranteed. Moreover, to expand domestic demand, especially investment demand, there are long-term "strategic" considerations: not simply to let enterprises "survive", but also to focus on meeting the new industrial revolution, cultivating new development momentum, and increasing investment in new technologies, new industries and new business models; Focus on maintaining the relatively complete manufacturing advantages of China’s industrial chain, and increase investment in the shortcomings and weaknesses of the industrial chain in order to win a better future.

  Liu Shijin:To cope with the impact of the epidemic and achieve steady growth, the current policy focus must be on stabilizing consumption. In the past, when we encountered economic downturn, our first thought was to expand investment demand, especially infrastructure investment, which was related to the economic structure and the growth stage at that time. For example, in 2008, in response to the impact of the international financial crisis, a 4 trillion stimulus plan was implemented. At that time, in the GDP increment calculated by the expenditure method, investment accounted for 62.8%, consumption accounted for 42.5%, and investment accounted for more than consumption, so the demand stimulus was mainly to expand investment demand. By 2019, in the GDP increment calculated by the expenditure method, the proportion of investment has dropped to 17.2%, the proportion of consumption has risen to 66.9%, and the proportion of household consumption has reached 49.5%. The proportion of consumption is far greater than that of investment, which shows that the key to steady growth at this stage should be to stabilize consumption, especially household consumption.

  2. New opportunities, new features and new requirements for expanding domestic demand strategy.

  Moderator: Focusing on the strategy of expanding domestic demand, the Politburo meeting of the Chinese Communist Party held on April 17th made arrangements from many aspects, such as stimulating consumption and investment, and promoting people’s livelihood security. What impact will these measures have on enterprises and individual residents?

  Han Baojiang:The strategy of expanding domestic demand will bring many opportunities to enterprises. Expanding residents’ consumption and increasing public consumption will stimulate the demand for "high-quality necessities", such as health care, culture and entertainment, tourism and leisure, low-carbon ecology and other industries, which will usher in new and greater development space. The state will increase its investment in "new infrastructure", which is not only of great benefit to many enterprises directly related to "new infrastructure", but also can more effectively promote the development of traditional industries such as steel, cement and construction. Therefore, enterprises should closely follow the national policies and find and seize the development opportunities that suit them.

  The positive impact of the strategy of expanding domestic demand on individual residents mainly comes from the policies closely related to the production and life of ordinary people, such as ensuring employment, ensuring basic livelihood, encouraging residents’ consumption and increasing the transformation of old residential areas. For example, under the impetus of relevant policies, enterprises’ efforts to reduce prices and promote sales will bring cheap goods and "consumer surplus" to consumers, the state encourages automobile consumption and other policies to bring new "demand satisfaction" to consumers with corresponding needs, and the transformation of old communities will directly improve the living and living quality of residents.

   Liu Yuanchun:It will have a significant positive impact on the development of enterprises. China is in the stage of rapid development of new industrialization, informationization, urbanization and agricultural modernization, and the investment demand potential is still huge. Judging from the published fiscal policy, effective investment will be actively expanded in the future, including the renovation of old residential areas, strengthening investment in traditional infrastructure and new infrastructure, and expanding investment in strategic emerging industries. These measures have increased the support for private capital to participate in projects in key areas, which is conducive to mobilizing the enthusiasm of private investment. Enterprises, especially the vast number of private and small and medium-sized enterprises, should seize the opportunity and expand their own development space. On April 17th, Politburo meeting of the Chinese Communist Party proposed "supporting enterprises to export to domestic market" and supporting some foreign trade production capacity to domestic market, which is also the breakthrough point for enterprises to adapt to positive macro policies and promote their own development. The benefits of individual residents in the strategy of expanding domestic demand are direct and concrete. Judging from the policies that have been promulgated, it can directly enhance the purchasing power of residents and improve the living standards of special groups.

  Moderator: What macro-policy measures are usually adopted to expand domestic demand? What are the new features of the current domestic demand expansion strategy compared with the previous domestic demand expansion policy?

  Han Baojiang:The macro-policy measures to expand domestic demand are mainly proactive fiscal policy and prudent monetary policy. At present, the requirements of the central government are: the proactive fiscal policy should be more active and promising, and some measures and requirements have been put forward, such as improving deficit ratio, issuing special anti-epidemic bonds, increasing special bonds of local governments, and improving the efficiency of fund use, so as to give greater play to the role of proactive fiscal policy in stabilizing the economy; A prudent monetary policy should be more flexible and appropriate, including the use of RRR cuts, interest rate cuts, refinancing and other means to maintain a reasonable and abundant liquidity, guide the interest rate in the loan market to fall, and use funds to support the real economy, especially small and medium-sized enterprises, and so on.

  Some supply-side structural reform policies, industrial policies and social policies aimed at improving the quality of China’s economic development and improving labor productivity and total factor productivity have also been added to the policy of expanding domestic demand. These policy measures have jointly formed a "policy combination boxing" with China characteristics, which is also a policy system to realize the modernization of China’s economic governance. There are still many specific measures to expand domestic demand, and at present, there are still many tools in our policy toolbox that have not been taken out.

  A notable feature of the current strategy of expanding domestic demand is that it does not engage in flood irrigation, but starts from promoting the high-quality development of the national economy and meeting the needs of the people’s better life, and exerts its strength from both the supply side and the demand side, aiming at the structural contradictions and shortcomings in the development of the national economy, and provides the right medicine and precise policies. The focus of the policy is to solve the problem of insufficient imbalance in the development of social productive forces, and on this basis, actively cultivate new economic growth points and form more new kinetic energy for economic development.

  Liu Yuanchun:At present, the macro-economic policies to expand domestic demand focus on people’s livelihood assistance, economic stimulus and the reform to turn crisis into opportunity, which mainly show the following characteristics: fiscal policy expansion is the main body, supplemented by monetary policy; Take the project layout as the guide and follow up with capital investment; The combination of epidemic relief and short-term expansion, short-term stimulus and medium-term development; Based on bottom line management and camera decision-making, it will be gradually promoted in stages; Demand expansion is coordinated with supply management, consumption start-up and investment expansion are parallel, and multi-channels and multi-tools are implemented simultaneously.

  The policy of expanding domestic demand is being implemented, and the fiscal policy includes three categories, totaling 23 items, with a total expenditure of 1.3 trillion yuan and an implementation amount of more than 500 billion yuan; Monetary policy includes 30 financial supports and a monetary policy promotion plan, with a total of 4.4 trillion yuan of financial support. In terms of consumption promotion policies, 23 departments have issued 19 categories of policies, and many places have also issued policies such as providing consumer vouchers and income subsidies in coordination with epidemic relief; The investment promotion policy focuses on old and new infrastructure, and the investment expansion policy focusing on "new infrastructure" will effectively improve short-term demand and provide a better foundation for high-quality development.

  Moderator: Under the premise of normalization of epidemic prevention and control, promoting "six stabilities" and grasping "six guarantees" are the main focus of persisting in striving for progress while maintaining stability and grasping all aspects of economic and social development. How to combine expanding domestic demand with promoting "six stabilities" and "six guarantees"?

  Han Baojiang:The "six guarantees" are the "policy bottom line" for implementing the strategy of expanding domestic demand. In other words, no matter the policy of expanding consumer demand or investment demand, we should make overall arrangements for the "six guarantees", the active fiscal policy should be more active in the "six guarantees", and the prudent monetary policy should be moderately loose in the "six guarantees" field.

  Among them, I pay special attention to ensuring residents’ employment, basic people’s livelihood and market players. To ensure employment, it is necessary to do a good job in the employment of key industries and key groups, and the employment of college graduates should be the top priority in the near future. To ensure the basic livelihood, we need to do a good job in ensuring people’s livelihood, increase the intensity of poverty alleviation, and ensure that the task of poverty alleviation is fully completed as scheduled; Improve social security and ensure the basic livelihood of the people. To protect the main body of the market, it is necessary to speed up the implementation of various policies, and strive to help small and medium-sized enterprises tide over the difficulties and improve their survival and development capabilities by reducing taxes and fees, financing costs and housing rents. Protecting market players is helpful to maintain the stability and competitiveness of China’s industrial chain supply chain, and promote the coordinated resumption of production and production in the industrial chain.

  Liu Yuanchun:The combination of expanding domestic demand and the goals of "six stabilities" and "six guarantees" embodies the basic idea of "bottom line management" of economic policy. Expanding domestic demand can not only help macroeconomic stability, but also guarantee the basic livelihood of grassroots people and help maintain social stability. Only an adequate demand management policy can ensure that the economic system can quickly return to normal after the shutdown, so that enterprises can get enough orders to maintain normal operation after the resumption of work and production, and avoid stopping work and stopping production again and dismissing workers. Therefore, demand recovery and moderate demand expansion are the most fundamental methods to ensure residents’ employment and the foundation to protect market players. It ensures the basic employment of residents and the normal operation of market players, which also guarantees the basic livelihood of the people. Wage income and operating income are the core of residents’ income and the basis of fiscal revenue. The normalization of fiscal revenue is not only the basis of various public utilities and transfer payments, but also the basis of the normal operation of local governments. In the above sense, expanding domestic demand is the core and foundation of "six stabilities" and "six guarantees" and the key to ensuring the basic operation of the economy and society.

  Regardless of "six guarantees" or "six guarantees", the first place is employment. According to estimates, every percentage point increase in China’s GDP will bring about 2 million jobs, but every percentage point increase in GDP will bring about nearly 4 million unemployment. Therefore, we must fully realize the seriousness of completing the employment task and turn the goal of ensuring and stabilizing employment into a policy goal and policy action to expand domestic demand.

  3. Make a good combination of policies to ensure the synergy of macro policies.

  Moderator: The central government has proposed to hedge the impact of the epidemic with greater macro-policy, a proactive fiscal policy, and a prudent monetary policy. How can fiscal policy and monetary policy work together to expand domestic demand?

  Liu Yuanchun:In the policy combination of crisis relief, monetary policy is often the main policy, supplemented by fiscal policy. However, this traditional coping policy faces more constraints and constraints when dealing with the economic downturn caused by the epidemic. First of all, the traditional monetary policy is to create a relaxed environment conducive to enterprise investment and household consumption by lowering interest rates and expanding money supply. However, when economic activities are interrupted and the industrial chain is broken, the cash flow income of families and enterprises is interrupted, and they are uncertain about their future expectations, and often have no willingness to expand consumption and investment. At this time, too much emphasis on monetary policy, increasing liquidity and encouraging debt consumption or investment may make families and enterprises bear a heavier debt burden. Therefore, the response of households and enterprises to monetary policy is often low. Secondly, the traditional fiscal policy helps to reduce the cost of enterprises by reducing taxes and fees, but it has limited help to expand investment demand. In the state of stagnant production activities of enterprises, tax reduction and fee reduction are conducive to reducing the fixed costs of enterprises, so that enterprises can last longer without income cash flow. However, in the absence of downstream demand, enterprises are unwilling to resume work and production, and the stimulating effect of tax reduction and fee reduction policy on expanding enterprise production and investment is limited.

  Under the limited means of traditional monetary policy and fiscal policy, what is needed to restart the economy is a one-time total demand, especially the final demand. The expansion of final demand can realize bottom-up transmission along the industrial chain and become the exogenous driving force for the economy to break away from the suspended state. Before the uncertainty of epidemic situation and market risk are eliminated, this exogenous driving force mainly depends on government expenditure. Once the economy begins to recover, the normal economic operation mechanism will begin to play a role, and the role of traditional expansionary monetary policy and fiscal policy will gradually emerge.

   Han Baojiang:Theoretically, in the macro-control system, there is a division of labor between fiscal policy and monetary policy. Although both of them can play a role in expanding the economic aggregate, fiscal policy is more capable of solving structural problems and making more precise policies. Although monetary policy can also play a structural role through policy tools such as differential interest rates, its advantage is mainly to solve the problem of loose or tight aggregate. Therefore, the two should have a division of labor, give full play to their own strengths, and cooperate to avoid the hedging of policy effects. For example, the purpose of structural tax reduction is to reduce the burden on small and medium-sized enterprises. If the tax burden is reduced and the problems of difficult and expensive loans are not solved, enterprises will also be unable to live or live well. Only when the two fluctuate at the same frequency and work together can enterprises realize the real burden reduction and survive the crisis well.

  Moderator: To maintain the overall situation of economic development and social stability, we must adhere to the new development concept, adhere to the supply-side structural reform as the main line, and persist in promoting high-quality development with reform and opening up as the driving force. How does the policy of expanding domestic demand organically cooperate with these requirements?

  Liu Shijin:The importance of demand policy lies in responding to the short-term impact of the epidemic. From the long-term development point of view, economic recovery and development still need to rely on exerting structural potential. For decades, China’s economic growth rate has been much higher than that of developed economies, mainly relying on its structural potential. This structural potential is the late-developing advantage in economics, and in layman’s terms, it is the development potential of a late-developing economy in terms of technological progress, upgrading of industrial structure and consumption structure, and urbanization process. Therefore, the strategy of expanding domestic demand in response to short-term shocks needs to be based on the long-term and coordinated with structural potential. The effective exertion of structural potential requires the supply policy to play a greater role, which means that we must firmly grasp the main line of supply-side structural reform and promote the continuous upgrading of supply structure.

  Supply policy and demand policy should be matched according to the different problems and main contradictions faced at different stages. For example, in the stage of epidemic control, it is necessary to increase the distribution of relevant emergency materials through supply policies, and in the stage of resuming production, it is necessary to use administrative means to promote the whole industry chain and the whole field, and then carry out corresponding demand-side policy cooperation.

  Han Baojiang:Policies to promote demand should work together with policies to promote reform. First of all, we must adhere to the party’s centralized and unified leadership over economic work, which is the institutional prerequisite for coordinating efforts. Secondly, the supply policy should be in tune with the demand policy. In other words, it is necessary to improve the adaptability of the supply structure to the demand structure, and increase the efforts to meet the middle and high-end demand on the basis of maintaining the general demand. Facts have proved that China’s demand is not insufficient, or there is no demand, but the demand has changed, but the products supplied have not changed, and the quality and service cannot keep up. The lack of effective supply capacity has brought about a large amount of demand spillover and a serious outflow of consumption power. To solve these structural problems, we must promote supply-side structural reform. Thirdly, the supply policy should strive to be "half a beat or a beat" earlier than the demand policy, and create "new demand" with "new supply". In today’s era, the prominent feature of socialized mass production is that once the supply side realizes successful subversive innovation, the market will respond with magnificent transaction generation. This is the truth.

  Liu Yuanchun:A few days ago, the CPC Central Committee and the State Council issued the Opinions on Building a More Perfect System and Mechanism for Market-oriented Allocation of Factors, which classified the reform directions and specific measures in the five areas of land, labor, capital, technology and data, and deployed and improved the formation mechanism of factor prices and the market operation mechanism. Global production and consumption have been comprehensively impacted by the epidemic, and China’s economic and social development is facing new difficulties and challenges. Firmly pushing forward major reforms and further improving the business environment will certainly stimulate the vitality and creativity of the whole society, release more new kinetic energy in the market, and provide a solid institutional guarantee for hedging the impact of the epidemic and increasing the stamina of China’s economic development.

  The impact of the epidemic is accidental and phased. The demand expansion policy is mainly introduced to deal with the short-term impact of the epidemic, and the policy based on stimulation cannot be used for a long time. Therefore, the demand policy should be exerted moderately and should not be overexerted. To achieve the annual economic and social development goals and promote high-quality economic development, we must focus on long-term development and firmly grasp the main line of supply-side structural reform.
