The key core technology is the most important tool of the country, which is of great significance in promoting the high-quality development of China's economy and ensuring national security. Since the 18th National Congress of the Communist Party of China (CPC), China has made a series of major achievements in aerospace, deep-sea exploration, satellite navigation, energy technology and other fields by giving play to the advantages of the new national system, and made significant progress in tackling key core technologies. Not long ago, the 27th meeting of the Central Committee for Comprehensively Deepening Reform deliberated and adopted the Opinions on Improving the New National System for Tackling Key Core Technologies under the Conditions of a Socialist Market Economy, which will strongly promote the further improvement of China's new national system, form a strong joint force for tackling key core technologies, and give play to China's institutional, market and talent advantages, Accelerate the realization of high-level science and technology to lay a foundation for self-reliance. We will promote better integration between an effective market and a promising government. Key core technologies are characterized by high investment, long cycle, complexity, strategy and monopoly, which requires us to give full play to the remarkable advantage of our socialist system in focusing our efforts on major issues, strengthen the leadership of the Party and the state on major scientific and technological innovation, optimize the allocation of innovation resources based on the national strategic needs, so as to strengthen the national strategic scientific and technological strength, improve the systematic ability to tackle key scientific and technological problems, and form a competitive advantage Win strategic initiative. In this process, we should make full use of the favorable role of the market mechanism. China's super large market is the fundamental driving force to promote key core technology research. The super large market means more innovation scenarios, lower innovation costs and higher innovation benefits. China is in a critical period of industrial optimization and upgrading. The size of the middle-income group has exceeded 400 million, the number of Internet users has exceeded 1 billion, and the people's demand for a better life is growing. These realities have created ideal development space for the rapid industrialization and scale of various key core technologies. At the same time, the super large market also means a better competition and innovation ecology, which can better share the input costs of key core technologies, ensure commercial sustainability, and promote the early deployment of technology applications, so as to seize the commanding heights and win the first opportunity. Promote better integration of goal realization and economic benefits. The new nationwide system aims at a number of key areas and major tasks related to China's industry, economy and national security, and focuses on the research and development of key technologies with first mover advantages and basic cutting-edge technologies leading future development. Although it has the same clear goal orientation as the traditional national system, the new national system more respects economic laws and market laws, and attaches great importance to incentive issues. Promoting the better combination of goal realization and economic benefits means building a reasonable and effective incentive mechanism to mobilize the enthusiasm of participating institutions and personnel. The ultimate goal of the traditional national system to conquer key core technologies is "non market" products, while most of the "choke" technologies we face under the new national system are part of commercial projects, and many scientific research achievements will eventually be converted into commodities to obtain more
