长三角地区营商环境对外商直接投资影响的实证研究

An Empirical Study on the Impact of Business Environment on Foreign Direct Investment in Yangtze River Delta

基于长三角城市群2010—2020年的面板数据,构建营商环境总指标及四类子环境指标,即市场环境、创新环境、政务环境和公共环境,利用熵权法来测算指标权重,最终得出综合得分。通过对空间计量模型选择的检验,探究营商环境及其子环境对外资的影响。结果表明,营商环境会显著的促进外资的流入,其中,子环境中的市场环境、政务环境对外商直接投资会产生显著的正向空间溢出效应;创新环境和公共环境会对外商直接投资产生较弱的负向空间影响。根据结论提出长三角地区应继续努力提升地区营商环境水平、进一步优化营商环境子环境、地区政府因地制宜采取相应策略和多方面考量为地区FDI流入助力的政策相关建议。

Based on the panel data of the Yangtze River Delta urban agglomeration from 2010 to 2020,this paper constructs the total index of business environment and four sub-environmental indicators,namely market environment,innovation environment,government environment and public environment and measures the index weight by using the entropy weight method.Through the test of spatial econometric model selection,this paper uses the Spatial Durbin Model(SDM)with time fixed effect to explore the impact of business environment and its sub-environment on foreign investment.The results show that the business environment will significantly promote the inflow of foreign capital.Among them,the market environment and government environment in the sub-environment will have a significant positive spatial spillover eff ect on foreign direct investment.Innovation environment and public environment will have a weak negative spatial impact on foreign direct investment.Based on the findings,it is proposed that the Yangtze River Delta region should continue to strive to improve the level of regional business environment,further optimize the sub-environment of business environment,and the regional government should adopt corresponding strategies and multi-faceted considerations to assist regional FDI inflows.
