The Effect and Mechanism Test of the Depth of Regional Service Trade Agreement on the Resilience of Global Value Chain of Enterprises
It is very important to explore how the depth of regional service trade agreements(RSTAs)affects the resilience of global value chains(GVCs)of enterprises in the context of complex and changeable international situation,so as to achieve a high level of opening up,build a new development pattern and maintain national economic security and stability.This paper uses DESTA database,UIBE GVC database and China Customs database to construct RSTAs depth index and enterprise GVCs resilience index respectively,and explores the effect of RSTAs depth on enterprise GVCs resil-ience and its internal mechanism from the perspective of safety and stability.This paper uses DESTA database,UIBE GVC database and China Customs database from 2000 to 2015 to construct RSTAs depth index and enterprise GVCs resilience index,to explore the effect of RSTAs depth on enterprise GVCs resilience and its internal mechanism from the perspective of safety and stability,and uses 45 industry data from 2005 to 2020 to further verify the robustness of micro results.The regression results show that the depth of RSTAs can significantly improve the resilience of corpo-rate GVCs,and it is still valid after a series of robustness and endogeneity tests such as tail reduction,elimination of financial crisis interference,survival analysis,industry-level test,instrumental variable method and replacement of regression model.The results of heterogeneity analysis show that the influence of RSTAs depth on the resilience of enterprise GVCs is different due to the different enterprise life cycle,technical complexity,national development level and enterprise GVCs location.The results of the mechanism analysis show that RSTAs depth enhances the resilience of GVCs by reducing trade costs,enhancing the status of trade networks and improving the institutional environment.Further analysis results show that although the signing of RSTAs under regional competition can significantly improve the resilience of enterprises'GVCs,the"Shielding effect"and"Dilution effect"caused by different contracting time regulate the effect of RSTAs on the resilience of enterprises'GVCs.This paper provides a sci-entific decision-making basis for promoting China's signing of high-level RSTAs and improving the resilience of corporate GVCs.
