Abstract: Currently, new infrastructure can generate various positive economic effects, which have been widely confirmed by theoretical and empirical research. However, existing research has paid little attention to its impact on the participation of the manufacturing global value chain (GVC). In terms of research perspective, unlike existing literature that focuses on traditional infrastructure, this article focuses on exploring the factors that affect China’s participation in the division of labor in the global value chain from the perspective of the role of new digital infrastructure, so as to expand and deepen the understanding of the factors that affect China’s participation in the global value chain. In terms of research content, this article analyzes the mechanism of the impact of new digital infrastructure on China’s participation in the global value chain at both theoretical and empirical levels. From the perspective of new digital infrastructure construction, it can explore better countermeasures and suggestions to promote China’s climb up the global value chain. In terms of research methods, especially in the construction of indicators for the division of labor in the global value chain, this article also attempts to break through the shortcomings of existing literature in constructing indicators, and innovatively constructing scientific indicators from the enterprise level that can better reflect the division of labor in the global value chain. The research findings indicate that the Chinese manufacturing industry urgently needs to further integrate into the global value chain, enhance the division of labor in the global value chain, and move towards a critical stage of high-level openness, which has important policy implications.
