Research on the Upgrading of China's Manufacturing under the Value-Added Capability and Correlation Effect of Global Value Chain

China's manufacturing has developed rapidly due to the integration of the global value chain (GVC) production division system. But the early OEM and processing can hardly meet the needs of high -quality development of the manufacturing. The "low -end lock -in" and "double squeeze" faced by China's manufacturing will impede the pace of upgrading the manufacturing. From the perspective of GVC accounting, this paper studies the industrial chain upgrading of China's manufacturing industry through four indicators: GVC participation, GVC division of labor status index, share of foreign value added in domestic exports, and manufacturing 'servitization' index, which from the value chain value added effect at the national level and industrial chain correlation effect at the industrial level, and drawing on the WWYZ method of Wang Zhi et al. (2017) and the input-output method of Leontief (1936). Through the research, it is found that the servitization level of the mid and high-tech industry and high-tech industry of China has been steadily improved, gradually getting rid of the "low -end lock -in" of developed countries and climbing to the high value added production links; Not only do the reindustrialization strategy of developed countries provide the obstacle to the upgrading of the industrial chain and value chain of China's high-tech industry, but also promote domestic talent training and technological innovation. The linkage and integration of the industrial chain of low -tech industry and low and mid -tech industry have been further improved, which plays a favorable role in relevant industry's value chain climbing and industrial chain upgrading. China's manufacturing is progressively improving its own value-added capability and international competitive advantage, further enhancing the two-way integration of the industrial chain, and gradually transitioning to both sides of the "smile curve", to achieve high -quality development of the manufacturing.
