The characteristics of China’s manufacturing industry are large, lacking in competitiveness, and there is a clear gap between developed countries’ manufacturing in the fields of independent innovation capacity, resource utilization efficiency, industrial structure level. It is necessary to restructure the entire manufacturing industry. The Chinese government released "China Manufacturing 2025" on May 8, 2015, and officially announced it on May 19. In particular, it focuses on eco-friendly improvement of traditional manufacturing facilities that have been the basis of economic growth in the past, such as the steel industry. Specifically, it is a traditional manufacturing industry such as steel and related ineffectiveness of facilities and factories are being applied. As a result, the following results were obtained. First, according to the results of analysis of the influence coefficient of Chinese steel industry in 2012, it was derived in the order of special equipment manufacturing, other manufacturing and weighing/measuring equipment manufacturing. As a result of the analysis, in 2007, if the conventional traditional manufacturing industries such as metal products, electricity, machinery and equipment manufacturing, metal smelting and rolling industry, It can be concluded that the rear industry group, which has added technical and expertise, has been changed. Second, the sensitivity coefficients of the Chinese steel industry in 2012 were analyzed in the order of chemical industry, metal smelting and rolling, and power/heating production and supply. Compared with the results in 2007, it can be seen that the downstream industries of the steel industry, that is, the raw materials industry and the raw materials industry, which are the basis of the traditional manufacturing industry in China, It is possible to analyze why the Chinese government’s Chinese manufacturing 2025 strategy is being pursued.
