国际知识资本溢出对全要素生产率的影响——基于中国省级面板数据实证研究

国际知识资本溢出是推动全要素生产率的重要引擎。基于中国30个省份2000—2018年面板数据,利用双向固定效应模型研究进口溢出的知识资本和FDI溢出的知识资本对全要素生产率的影响。研究结果表明:两类国际知识资本均对全要素生产率有显著促进作用,进口溢出的知识资本促进弹性大于FDI溢出的知识资本,但在加入交叉项后两者存在显著的抑制效应,这主要是由于跨国公司内部贸易的技术封锁导致;国际知识资本对全要素生产率的影响具有区域异质性,对东部的促进效应明显优于中西部。这一发现为我国更高效地利用国际知识资本进行区域间协调高质量发展提供了理论依据。

The Influence of International Knowledge Capital Spillover on Total FactorProductivity: Based on the Research on Chinese Provincial Panel Data

International knowledge capital spillover is an important engine to promote total factor productivity.Based on the panel data of 30 provinces and cities in China from 2000 to 2018,this paper uses the two-way fixed effect model to study the impact of knowledge capital of import spillover and FDI Spillover on total factor productivity.The results show that:the two types of international knowledge capital have a significant role in promoting total factor productivity,the promotion elasticity of knowledge capital of import spillover is greater than that of FDI spillover.But there is a significant inhibitory effect after the cross item is added,which is mainly caused by the technical blockade of the internal trade of multinational companies.The influence of international knowledge capital on total factor productivity has regional heterogeneity and the promotion effect of the eastern region is better than that of the central and western regions.This finding provides a theoretical basis for China to make more efficient use of international knowledge capital for coordinated and high-quality development among regions.
