外商直接投资、地区腐败与环境污染——基于门槛效应的实证研究

FDI,Regional Corruption and Environmental Pollution:An Empirical Research Based on Threshold Effects

本文以1995-2008年中国29个省级地区和2004年120个地级城市为研究对象,分别用门槛面板回归和截面交叉项估计的方法,实证考察了外商直接投资(FDI)对环境污染的腐败门槛效应以及地区腐败本身对环境的影响。研究结果表明,FDI对环境的影响存在显著的腐败门槛效应。在地区腐败水平较低时,FDI改善了当地的环境质量;而当地区腐败水平较高时,FDI则加剧了当地的环境污染;地区腐败本身也直接增加了中国各地区的污染排放。

： Using panel data dated between 1995 and 2008 from China＇ s 29 provinces as well as transverse data from China＇ s 120 cities of 2004, this pa- per draws on the threshold regression of panel data and transverse cross-term esti- mations to make an empirical investigation into the influence of foreign direct in- vestment （FDI） on corruption threshold effects and the impact of regional corrup- tion on local environmental pollution, as well as the effects of region corruption on environmental pollution. The results show that there are significant corruption threshold effects on the environment resulted from FDI. Concretely, when local corruption level is moderate, the intervention of FDI is positively correlated with local environment; when local corruption level is high, however, FDI works to de- grade local environment. Furthermore, regional corruption directly contributes to the increase in pollutant discharge in China.
