High-end equipment manufacturing is an important support for national economy and national defense construction, and it is also the core engine and key point for China to win the right of international discourse and promote industrial transformation and upgrading. This paper analyzes the internal logic and identifies key obstacles of substitution adoption the high-end equipment made in China, and then discusses the breakthrough path based on practical cases, which are main and distribution cooperation, demand traction, demonstration leading and ecological integration. It also puts forward some policy suggestions in terms of promoting the synergy of upstream and downstream of the industrial chain, optimizing the application ecology of domestic high-end equipment and strengthening the pilot demonstration of domestic high-end equipment.

Currently, key strategic materials of China are partly subject to control by other countries, facing the dilemma of "choking". Domestic substitution of key strategic materials is in urgent need of further breakthrough. This paper systematically analyzes the present situation and existing problems of domestic substitution in the field of key strategic materials. Further, the breakthrough points of key strategic materials domestic substitution are discussed by analyzing the process and industrial characteristics. On this basis, the bottleneck problems faced by key strategic materials domestic substitution at the present stage and the key capabilities that need to be built urgently are analyzed. Finally, based on the common innovation experience of material powers such as the United States, the European Union and Japan, strategic measures and policy suggestions are put forward from the perspective of technological innovation systems to promote domestic substitution of key strategic materials.

The realization of domestic replacement of industrial software is the key to the transformation of China's industrial system to high-end and intelligent. In response to the U. S. suppression of China's industrial software development, and to explore the road of domestic replacement of industrial software, this paper compiles the development status and the degree of domestic substitution for four types of industrial software: R&D design software, production control software, business management software and embedded software, and analyzes the problems of the various types of domestic industrial software from the aspects of“have”and“use”. It also reviews and summarizes the development history and learning experience of the world's industrial software powerhouses such as the United States, Germany and France. Focusing on the two aspects of "have" and "use", the paper proposes countermeasures to design innovation breakthrough path and build application incentive mechanism respectively. Finally, this paper systematically proposes multi-faceted policy recommendations for the replacement of industrial software.

At present, the new round of scientific and technological revolution and industrial change is accelerating the evolution. The Yangtze River Delta has obvious advantages in science and technology innovation, regional talents, science and technology, and manufacturing industry. Moreover, The Yangtze River Delta also possess a number of innovation communities and industrial clusters with strong international competitiveness whose industry and supply chain is relatively complete, and market potential is huge, which has the foundation and advantages to construct and develop the modernization of IC industry chain. This paper focuses on the modernization development of the IC industry chain and the improvement of the competitiveness of the IC industry in Yangtze River Delta. Firstly, we analyze the current situation of the development modernization of the IC industry chain, and put forward the problems faced by the IC industry chain in the Yangtze River Delta through the pattern of the current situation of the industry. To sum up, we pointed out the modernization development path of the IC industry chain in Yangtze River Delta from four aspects: strengthening key core technologies, optimizing the division of labor and collaboration of the industry chain, relying on leading enterprises to lead the synergistic development of the whole industry chain, and accelerating the attraction of high-end talents.

The integrated circuit industry has become the key field and important means of great power competitions, for its fundamental, strategic and leading role. By summarizing and sorting out the development status of China's integrated circuit industry, and analyzing the development difficulties faced by China in the chip field, it is found that China not only has weak basic development, lack of innovation and other weaknesses in the chip field, but also has incomplete industrial ecology, and also faces the increasing export control policies of the United States. In view of the current situation of these problems, based on the present status of the chip field, we put forward some suggestions on giving consideration to the key points, multi-point layout, giving full play to the advantages of the new national system, strengthening basic research and innovation, and warning science and technology security.

As the key hardware of the autonomous driving perception layer, the vehicle-mounted intelligent sensor is not only related to the military unmanned ground vehicle system but also related to the automatic driving technology of civilian vehicles, which seriously affects the national defense security and industrialization development of China. In recent years, the United States has issued export control measures related to chips and software, which have seriously affected the development and safety of China's automotive smart sensor industry. At present, autonomous driving is in the transition stage from L2 to L3. Grasping this technological transition period may enable China to achieve corner overtaking and break the monopoly position of European and American countries in the field of on-board smart sensors. This paper summarizes the development trend of vehicle-mounted smart sensors under the background of autonomous driving, analyzes in detail the major challenges that affect the development and safety of China's vehicle-mounted smart sensor industry, and puts forward relevant suggestions to deal with the safety of industrial development.

In order to explore the present situation and development trend of science and technology security research, this paper makes comprehensive analysis and comment on the research of science and technology security at home and abroad from the elements, structure, function and external environment of science and technology security based on system theory. The research shows that science and technology security has strong integrity, hierarchy and linkage, and future research should focus on the governance of science and technology security, the construction of science and technology security early warning and monitoring system, the impact and evaluation of science and technology security on the overall national security.
