Abstract: The development of digital economy has a systemically impact on the global manufacturing value-added trade network. Based on the ADB?MRIO2022 database, this paper uses cutting-edge directed weighted complex network analysis method to characterize the characteristics, dynamic evolutionary trend of the global manufacturing value-added trade network and position change of China?s manufacturing industry in the global value-added trade network from 2010 to 2021, and empirically examines the impact of digital economy on the position of a country?s manufacturing industry in the value-added trade network. The results show that the regionalization of value-added trade in manufacturing industry is increasing, especially in Americas, the United States is gradually dispersing trade risk, diversifying export markets, reducing the vulnerability of its dominant local area network, yet China’s high trade dependence on the United States is not conducive to China-oriented local network dealing with specific impact. China occupies a central position in the global manufacturing value-added trade network, but there is room for further rise in the high-tech manufacturing network. On the whole, the development of digital economy is conducive to improving a country?s ability to control core resources, hold netting advantage and expand trade influence in the global manufacturing value-added trade network, but it can only significantly promote the closeness centrality of countries in the center and near center of the network. In order to break the manufacturing blockade dilemma of developed countries, emerging economies must enhance value-added trade flow and value creation ability, and realize the relative diversification of main export target countries. This paper finds that the reconstruction of the anti-globalization industry chain and supply chain may have long-term structural characteristics, revealing the great importance and urgency of using digital economy to promote China?s manufacturing industry from low and middle end to high end and fully release its huge potential of development.
