Manufacturing industry is the material basis of national economy and the main body of industrialization. Highly developed manufacturing industry is a necessary condition for industrialization and an important symbol of a country's comprehensive competitiveness. The inter-manufacturing effect emphasizes the static resource allocation between manufacturing industries, while the entry and exit of manufacturing industries emphasize the process of dynamic resource allocation between manufacturing industries. The previous literature on environmental regulation paid more attention to the influence of environmental regulation on the technological progress of manufacturing industry, and the research on the resource allocation effect of environmental regulation was insufficient, and even less on the dynamic resource allocation effect of manufacturing industry. In this regard, this paper optimizes the allocation of manufacturing resources in China from the perspective of economics, and the rapid economic growth will also provide opportunities for the leap-forward development of productive forces. Under the condition of not affecting the current production plan and production state, the manufacturing industry can optimize the use of idle resources of its own manufacturing units and integrate the superior resources of external manufacturing units to manufacture complex products that meet the requirements of users with faster speed, better quality and lower cost, so as to win the market.
