The key core technology is an important tool of our country, which is of great significance to promote the high-quality development of China's economy and ensure national security. *** It is emphasized that "we should strengthen the original and leading scientific and technological research, and resolutely win the battle of key core technologies" and "we should give full play to the remarkable advantages of China's socialist system in concentrating on major events and fight the battle of key core technologies" "We should face the world's scientific and technological frontier, the main battlefield of the economy, the major needs of the country and people's life and health, strengthen basic research and applied basic research, lay a good battle for key core technologies, and accelerate the transformation of scientific and technological achievements into real productive forces". All these provide guidelines for accelerating the self-reliance and self-improvement of high-level science and technology and realizing the goal of building a world scientific and technological power. From the perspective of domestic development, fighting the battle of key core technologies is a major measure to base on the new development stage, implement the new development concept and build a new development pattern. We need to closely follow the strategic arrangement of China's economic and social development, adhere to the demand orientation and problem orientation, comprehensively enhance the ability of scientific and technological innovation, and accelerate the formation of an economic system and development model with innovation as the main guide and support. From the perspective of the external environment, fighting the battle of key core technologies is the first chess to actively deal with the new round of scientific and technological revolution, industrial reform and external risks. Today's world is experiencing great changes that have not been seen in a century. China is facing not only the great opportunity of catching up and surpassing, but also the severe challenge of widening the gap. We need to make a difference in important scientific and technological fields, achieve more "0-1" breakthroughs and win the initiative in international competition. In this context, it is very important to deeply understand the significance of concentrating on key core technology and further study the main problems and countermeasures. Effective evaluation of existing difficulties To improve China's key core technology innovation ability, the first thing is to "find out the family background" and timely and effectively evaluate the existing difficult problems such as "what is missing" and "what is the difference". First, the problem of "neck sticking" in the field of science and technology is manifested in many aspects. The "neck sticking" problem is mainly reflected in key common technologies, cutting-edge leading technologies, modern engineering technology, disruptive technological innovation and so on. There are both problems facing industrial development and insufficient basic theoretical research. Specifically, at the industry level, some key links of some industrial chains rely on foreign supply, and there is a risk of industrial chain and supply chain disconnection. There is also a large gap between China and developed countries in the field of key common technologies such as basic materials and key components. For example, industrial software is a concentrated embodiment of the synergy of manufacturing industry at multiple levels such as materials, processes, machinery, control and application. Its vitality lies in the deep integration with industrial demand and the accumulation of application data. It is an important field for countries to obtain future competitive advantage in the new round of scientific and technological revolution and industrial reform. Due to the lack of market demand and data accumulation in China and the imperfection of industrial ecosystem, China's industrial enterprises pay more attention to the concept of "emphasizing application and neglecting R & D", resulting in the lack of competitiveness of China's industrial software enterprises. Second, the weakness of basic scientific research is still prominent. Basic research is the source of scientific and technological innovation. The root of many "neck sticking" technical problems faced by China is that the basic theoretical research can not keep up, and the source and bottom things are not clear. At present, there is a lack of major original achievements in China, the underlying basic technology and basic process capacity are insufficient, the bottlenecks in industrial motherboards, high-end chips, basic software and hardware, development platforms, basic algorithms, basic components and basic materials are still prominent, and the situation that key core technologies are controlled by people has not been fundamentally changed. It can be said that the more we extend to the upstream of the industrial chain and value chain, the weaker our independent and controllable ability and the lower the self-sufficiency rate of some links. To change this situation, the key is to continue to increase basic scientific research and strive to achieve breakthroughs in new structures and new materials. Third, it is difficult to effectively transform the potential of domestic demand into the driving force for the research and development of key core technologies. China's large-scale market and huge domestic demand potential can provide rich application scenarios and broad development space for scientific and technological innovation, and promote the rapid iteration, industrialization and large-scale application of new technologies. However, how to make full use of this advantage is an important issue. It is difficult to effectively transform China's core technology into the current domestic demand. On the one hand, out of concern about the reliability of new products and technologies, some enterprises are not willing to use new products and technologies. These new products and technologies are difficult to be recognized by the market, so it is difficult to achieve iteration and development maturity in the domestic market, and it is difficult for innovative enterprises to obtain funds for continuous R & D through new products and technologies, which objectively leads to the situation that domestic products gather at the middle and low end and R & D is in the tracking state for a long time. On the other hand, the relevant policies and management methods in some fields can not fully meet the market demand, which affects the judgment of market subjects on market opportunities, and then directly affects the overall profit, R & D investment and sustainable development ability of enterprises. Fourth, the organization of scientific and technological innovation faces new requirements. How to grasp the new opportunities of a new round of scientific and technological revolution and industrial reform is a problem of universal concern all over the world. New technologies and new trends put forward higher requirements for the organization of scientific and technological innovation. Under the new environment, the degree of scientific organization will be further strengthened, and the tackling of key core technologies will increasingly depend on the integrity and openness of the industrial chain ecosystem. Especially with the rapid development of digital technology, the paradigm and organizational model of scientific and technological innovation are undergoing systematic changes. The general trend of digital development has promoted consumer centered business reform. The non intermediation and networking of trading activities make "users" play an important role in tackling key core technologies, forming a new value creation mode of "user participation". At the same time, the characteristics of digital technology, such as high mobility, high dependence on data and multi-level interaction, enable the key core technology to achieve the barrier free flow of resource elements across regions, fields and organizations, which also greatly challenges the existing organization mode, coordination mode, management process and evaluation standard of resource allocation. Adhere to demand orientation and problem orientation Scientific research topic selection is the first problem to be solved in scientific and technological work. The choice of research direction should adhere to the demand orientation, proceed from the urgent and long-term needs of the country, based on China's existing advantages, and strive to solve practical problems. First, we should make full use of China's super large-scale market advantages to provide support for focusing on key core technologies. To solve the "neck" problem of key core technologies, the focus is to promote the effective transformation of domestic demand potential into the driving force of scientific and technological innovation. China's super large-scale market advantage plays a prominent role in promoting the industrialization and large-scale application of new technologies. The super large-scale market is conducive to stabilizing the sales revenue of technical products, effectively ensuring continuous innovation, stimulating the application and innovation of new technologies and promoting the rapid iteration of technologies. In this regard, we need to firmly grasp the main line of supply side structural reform, pay attention to demand side management, and strive to connect all links of production, distribution, circulation and consumption by continuously cultivating and expanding the domestic market, so as to open up the blocking points, make up the shortcomings and dilute the costs, so as to create a good environment for breaking through the key core technologies. At the same time, relying on the advantages of large-scale market, it can also gather global high-quality resources, form a higher-level dynamic balance between demand driving supply and supply creating demand, and promote the breakthrough of key core technologies and the improvement of industrial technology development level. Specifically, we should accelerate the cultivation of the market and attach great importance to the leading role of "high potential customers". According to the idea of "creating new demand with new application and driving new technology with new demand", aim at the needs of high potential customers with demonstration, influence and authority for ordinary customers, provide trial opportunities for influential and product application willing industry fields, and effectively guide, release and expand the consumption demand for key products. At the same time, we should actively implement the strategy of expanding domestic demand and continue to strengthen the leading demonstration of government departments. In view of the prominent problems such as insufficient domestic market demand and fierce competition in foreign market demand, supported by the construction of a number of national major engineering projects and the release of innovative application scenarios, we will promote the application of key products in key links and key fields in a reasonable and orderly manner in stages and steps, stimulate customers' enthusiasm to adopt key products and strengthen the connection between supply and demand, Give full play to the advantages of large-scale market. Second, in view of the still outstanding problems in basic scientific research, optimize the support methods and improve the overall efficiency of tackling key core technologies. We need to proceed from major national strategic needs and key scientific and technological issues, further strengthen the research and judgment of future scientific and Technological Development and application trends, determine and deploy the direction and focus of scientific and technological innovation, strengthen national strategic scientific and technological forces, promote the diversification of basic research investment subjects, and guide innovative resources to basic research and applied basic research; Focus on promoting the key core technologies of demand orientation and problem orientation, and support the high-quality development of the industry by enhancing the source supply capacity; Pay more attention to improving the efficiency of resource allocation and total factor productivity with reform dividends, and make efforts at some key points to achieve the effect of pulling one hair and affecting the whole body. Specifically, we should pay attention to overall planning, from the perspective of maintaining the safety and stability of the industrial chain supply chain, combined with the development reality of different regions, and in the process of implementing the industrial foundation reconstruction and industrial chain upgrading project, create a good innovation and development environment for industries with broad market prospects and provide support for industries with strategic value; We should focus on major forward-looking and strategic application directions, improve the level of investment in basic research, support capable enterprises to increase investment in basic research, and strengthen China's innovation ability in the fields of forward-looking basic research, cutting-edge leading technology and strategic high technology; We should focus on the industrial chain and ecosystem of key industries, give full play to the auxiliary role of modern technological means, carefully sort out the situation of each link in the upstream and downstream of the industrial chain and stakeholders in the ecosystem, collect and sort out information such as industry demand, major achievements, characteristic resources, important subjects and science and technology policies, and sort out the list of key technologies affecting the innovation and development of the industry Supporting the list of missing items and major problems, clearly grasp the outstanding advantages, weak links, obvious weaknesses and key needs of China's industrial chain and supply chain, put forward priorities, evaluate and organize forces to carry out integrated research and collaborative research. Third, guide upstream and downstream enterprises in the industrial chain to strengthen mutually beneficial cooperation in supply and demand guarantee and strengthen policy guarantee. The key to solve the "bottleneck" problem is to establish a market-oriented and multi-level industry university research collaborative innovation system, establish R & D alliances, overcome technical difficulties, and give better play to the incentive role of competition mechanism on market subjects. Specifically, we should establish an institutional mechanism to promote the effective connection between industry, University and research and cross regional cooperation, step up the layout of a number of major innovation platforms, accelerate the breakthrough of a number of key core technologies, and strengthen the support capacity of key links, key fields and key products. At the same time, the relevant policies of scientific and technological innovation should pay attention to "grounding" and make operational research in decision-making
