Do global innovation networks influence the status of global value chains? Based on a patent cooperation network perspective

Under the impact of economic globalization, the internationalization of production and trade has given rise to global value chains (GVCs) and global innovation networks (GINs); however, few studies have explored the link between these two networks. This paper constructs a global innovation cooperation network based on patent cooperation data and then analyzes the impact of different network characteristics on improving global value chain status. Empirical research shows that the characteristics of GINs significantly affect GVC status; the higher the eigenvector centrality and network connectivity, the higher the country's GVC status. Moreover, a higher degree of constraint is associated with a lower GVC status for the country concerned. The heterogeneity analysis further reveals apparent differences in the impact of GINs on different countries, manifesting as a catalytic effect in developed countries and as a disincentive in emerging economies; the effect is less apparent in developing countries. This paper provides theoretical support for the development of technological innovation activities and provides a reference for government departments to formulate policies on cross-border technological innovation cooperation.
