摘　　要：基于广东、广西两省(区)35个地级市2003—2017年统计数据,对城市异质性下FDI的环境污染效应及作用机制进行分析。通过基准回归初步判断规模、结构和技术效应对外商的投资与环境污染关系的影响。采用门槛回归模型对不同城市发展异质性下FDI的环境污染效应及机制进行分析。研究发现:高发展城市技术门槛显著,在技术门槛效应下,FDI的增加有利于改善环境污染状况;中发展城市在规模效应下,FDI与环境污染存在“U”型关系;低发展城市结构效应显著,FDI与环境污染存在倒“N”型关系。通过深入分析异质性差异下城市FDI的环境污染效应,协调区域发展规划,对实现地区绿色、可持续发展具有重要理论意义和实践意义。Based on the statistical data of 35 prefecture-level cities in Guangdong and Guangxi from 2003 to 2017,the environmental pollution effect and mechanism of FDI under urban heterogeneity are analyzed.The influence of scale,structure and technology effect on the relationship between foreign investment and environmental pollution is preliminarily judged by baseline regression.Then,the threshold regression model is used to analyze the environmental pollution effect and mechanism of FDI under different urban development heterogeneity.The results show that the technological threshold of highly developed cities is significant.Under the technological threshold effect,the increase of FDI is beneficial to the improvement of environmental pollution.Under the scale effect,there is a U-shaped relationship between FDI and environmental pollution in medium developing cities.The structure effect of low-development cities is significant,and there is an inverted N-shaped relationship between FDI and environmental pollution.It is of great theoretical and practical significance to coordinate regional development planning through in-depth analysis of environmental pollution effects of urban FDI under heterogeneous differences.
