General Secretary Xi Jinping pointed out in the "Several Major Issues of the National Medium and Long-term Economic and Social Development Strategy" that autonomous control is mainly aimed at areas, nodes, and important products related to national security. For Jiangsu, it is necessary to clarify and strengthen the focus of independent, controllable, safe and efficient industries as soon as possible, and explore the implementation path for the country to establish an industrial backup system. For Jiangsu, it is necessary to strengthen the construction of independent, controllable, safe and efficient industrial and supply chains as soon as possible, and explore the implementation path for the national establishment of industrial backup system.Building an independent and controllable modern industrial system should focus on industries with high influence and sensitivityFrom the perspective of industrial association, the selection criteria of key industries are the industries in which changes in one sector of the industrial system of the national economy will have a great impact on other sectors. Therefore, the basic strategy for Jiangsu to build an independent, controllable, safe and efficient modern industrial system should focus on improving the influence and control of industries with high influence and high sensitivity. Most of the industries with high influence in Jiangsu Province are concentrated in the traditional manufacturing sector, which has a great boosting effect on the national economy and social production. Most of the industries with high sensitivity are concentrated in the traditional service sector, which has a strong constraint on the development of various sectors of the national economy due to the large social demand. It can be seen that the industries with high influence and high sensitivity in Jiangsu are mostly basic industries that provide intermediate products in the upstream of the industrial chain.The focus of accelerating the construction of an independent and controllable modern industrial system through the coordination of the industrial chain: 1. Formulating a traditional industry innovation plan 2. Supporting small and medium-sized enterprises in entrepreneurship and innovation 3. Accelerating the integration and upgrading of industrial parks
