The impact of global value chain embeddedness on the innovation of high-tech enterprises

Innovation serves as the key engine of economic progress, and exploring how to improve the novelty level through opening up is a fundamental issue in the overview of global value chains. Based on the database of listed companies from 2008 to 2016 and the trade statistics of China Customs, this paper uses endogenous conversion model and threshold model to study the innovation effects on the global value chain engagement of Chinese high-tech firms. The findings indicate that being integrated into global value chains substantially enhances the innovation capabilities of high-tech firms, with a notable impact on state-owned enterprises and enterprises in high-innovation resource-based cities. Further research finds that with the deepening of the degree of high-tech enterprises' embedding in global value chain, the contribution of global value chain engagement to high-tech enterprise innovation has a nonlinear feature of "innovation potential lag - innovation fusion release - innovation capability dependence".
