空间效应视角下数字经济对FDI区位选择的影响研究

Research on the Impact of Digital Economy on FDI Location Choice From the Perspective of Spatial Effect

合理把握数字经济与FDI的深度融合,对于构建我国对外开放新格局具有重要意义。本文基于2000~2020年中国30个省域面板数据,采用因子分析法测度数字经济发展水平,并通过广义空间三阶段最小二乘估计和空间联立方程模型实证检验数字经济对FDI区位的影响及相应的空间溢出效应。研究发现:数字经济能够有效提升地区FDI吸引力,FDI的引入又能促进地区数字经济的发展;数字经济与FDI引入均存在显著的空间溢出效应;异质性分析表明,中、西部地区的数字经济发展水平提高对地区提升FDI吸引力的促进作用更为明显。本文的研究丰富了数字经济发展水平的测度方法,深化了对FDI区位影响因素的研究,为实现区域经济协调发展提供了政策参考。

A reasonable grasp of the deep integration of digital economy and FDI is of great significance for building a new pattern of China's opening to the outside world.Based on the panel data of 30 provinces(districts and cities)in China from 2000 to 2020,this paper uses factor analysis to measure the development level of digital economy,and empirically tests the impact of digital economy on FDI location and the corresponding spatial spillover effect through generalized spatial three-stage least square estimation and spatial simultaneous equation model.It is found that digital economy can effectively enhance the attractiveness of regional FDI,and the introduction of FDI can promote the development of regional digital economy.Both digital economy and FDI have significant spatial spillover effects.The heterogeneity analysis shows that the improvement of the development level of digital economy in the central and western regions plays a more obvious role in promoting the attractiveness of FDI.The research of this paper enriches the measurement method of the development level of digital economy,deepens the research on the location influencing factors of FDI,and provides policy reference for realizing the coordinated development of regional economy.
