国际知识溢出对浙江省区域创新的影响机制研究——基于FDI与国际贸易的双重考量

The Effects of International Knowledge Spillovers on Regional Innovation in Zhejiang Province:Based on FDI and International Trade

基于2001-2016年浙江省69个县域的面板数据,利用知识生产函数模型剖析了外商直接投资(FDI)和国际贸易的双重知识溢出效应对区域创新的影响机制,并探讨了经济发展水平、基础设施和人力资本在此溢出效应发挥过程中的交互作用。研究表明:浙江省区域创新能力发展后劲不足,近年来FDI和国际贸易增速也在减缓;国际贸易知识溢出对浙江创新能力存在显著的正效应,但FDI的知识溢出效应具有区域异质性,而且在不同的知识传导机制中,经济发展水平、基础设施和人力资本不同程度地促进溢出效应的发挥;与此同时,研发投入仍是提升区域自主创新能力的首要因素。

Based on the panel data of 69 counties from 2001 to 2016 in Zhejiang Province,we established two knowledge production function models to analyze the influence mechanism of FDI and international trade on regional innovation.Then we examined the role of economic development level,infrastructure construction and human capital in this process.The research shows that the development of regional innovation capacity in Zhejiang Province is insufficient,and the growth rate of FDI and international trade is also slowing in recent years.The knowledge spillover of international trade has a significant positive effect on regional innovation capability,while that of FDI has regional heterogeneity.In different knowledge transmission mechanisms,economic development level,infrastructure construction and human capital can promote the spillover effect to varying degrees.At the same time,R&D input is still the most essential factor in the improvement of indigenous innovation.
