Abstract: This article extends the total value-added trade decomposition method to the level of digital trade, constructs a digital measurement framework for the global value chain from the perspective of trade digitalization, analyzes the integration of China’s manufacturing industry in the digital global value chain from the dimensions of two-way digital correlation, digital dependence and international comparison, and analyzes the factors affecting the status of China’s manufacturing industry in the international division of labor with the hierarchical structure decomposition method. The main research conclusions are as follows: China’s manufacturing industry is mainly integrated into the digital global value chain division of labor through forward participation, and it is at the midstream level in the digital global value chain positioning. The developed economies led by the United States hold the dominant position of digital trade in the manufacturing industry. The digital value-added export of China’s manufacturing industry is strongly dependent on the markets of developed economies, in which the forward digital value-added export that is dependent on the economies is more widely distributed, while the backward digital value-added export that is dependent on the economies is more concentrated. The positive changes in the relative attribute factor of exporting domestic added value and the digital attribute factor of the global value chain can significantly improve the status of China’s manufacturing industry in the international division of labor.

Key words: digital trade, digitalization of global value chain, the status of the manufacturing industry in international division of labor
