The report of the 20th National Congress of the Communist Party of China proposed to accelerate the construction of a modern economic system, focus on improving Total factor productivity, and focus on improving the Supply chain resilience resilience and security level of the industrial chain. Smooth economic circulation requires orderly and efficient linkage among various industries. To adapt to the overall trend of industrial development, we need to promote the supplementation of weak industries, the extension of advantageous industries, the upgrading of traditional industries, and the construction of emerging industries, in order to enhance the continuity and competitiveness of industrial development. To build a modern industrial system with Chinese characteristics and achieve sustainable high-quality economic development, we must deepen our understanding of the industrial chain supply chain, strengthen the industrial chain Supply chain resilience resilience, and ensure the national Economic security. To improve the ability to resist risks, it is necessary to forge the industrial chain Supply chain resilience Industrial chain is a chain form formed by various industrial sectors in the economic system on the basis of certain technological and economic links, according to specific logic and space-time layout. The supply chain is a network chain that revolves around the core enterprise, starting from supporting parts, manufacturing work-in-process and intermediate products, and finally delivering the final products to consumers. The node of the industrial chain is the industry, which forms a functional network chain of different types of related industries; The nodes of the supply chain are enterprises, which connect suppliers, manufacturers, distributors, and end users into an overall network chain. The industrial chain reflects the technological connections between different industries from a macro perspective, aiming to optimize industrial connections and the division of labor layout of enterprises, improve the comprehensive competitiveness of the industry, and achieve value added of the industry; The supply chain reveals the flow and transformation of production factors, products, and resources from a micro perspective, aiming to promote effective collaboration between enterprises, reduce total production costs, and improve production and supply efficiency. The industries on the industrial chain continuously increase their value through technological and economic connections; Enterprises in the supply chain enhance their competitive advantage and enhance customer value through production and operation collaboration. The industrial chain supply chain is an important form of modern economy, which has a significant impact on the operation of the modern economic system. However, it is also greatly influenced by internal and external factors within the system. The evolution of global industrial layout, changes in industrial structure, and sudden domestic and foreign factors can all affect the stability of the industrial chain supply chain. Therefore, the industrial chain supply chain itself needs to have good economic resilience, which is the ability of the industrial chain supply chain to maintain its stability, self repair, self improvement, and prevent fractures. The resilience of the industrial chain supply chain reflects the ability of a country's economy to resist risks and determines its economic security. We must scientifically study and judge the trend and development trend of the global industry, accurately grasp the shape, structure and upgrading trend of the global industrial chain supply chain, forge the Supply chain resilience resilience of China's industrial chain, and improve the ability of the economic system to resist risks. Building an industrial chain supply chain with sufficient coordination capabilities. China is a country with a complete industrial sector and a huge production scale in the world, and the industrial chain supply chain has significant influence globally. The "long board" is the core element of industrial competitiveness and the core element of industrial competition. To identify the key focus and focus on industries with advanced technology, large production scale, long industrial chain, and promising development prospects, such as high-end equipment manufacturing, new materials, biopharmaceutical and high-performance medical devices, high-end electronic information manufacturing, high-end petrochemical production, advanced light textile manufacturing, and smart logistics
