本文利用1990—2006年江苏省的时间序列数据,以江苏省为例研究经济开放对环境的影响,发现外商直接投资的流入能够在一定程度上改善环境,同时外商直接投资是环境质量改善的Granger原因;而出口在一定程度上恶化了环境,同时出口增长是环境污染增加的Granger原因;外商直接投资与出口的共同作用是有利于环境质量的改善。这些研究表明,“污染避难所”假说在江苏省是不成立的,江苏省的环境污染问题主要是由于省内企业大规模出口造成的。
In this paper, we use the time series data of Jiangsu Province from 1990 to 2006, and take Jiangsu Province as an example to study the impact of economic openness on the environment. We find that FDI inflows can improve the environment to a certain degree, while FDI is Granger The reason is that exports have worsened the environment to some extent and the export growth is the Granger cause of the increase of environmental pollution. The combined effect of FDI and exports is conducive to the improvement of environmental quality. These studies show that the “pollution shelter” hypothesis is not established in Jiangsu Province. The pollution problem in Jiangsu Province is mainly caused by the large-scale export of enterprises in the province.
