文章考察了外商直接投资对我国生态效率的影响,认为FDI既对生态效率产生直接影响,也会通过促进经济增长、环境技术进步对生态效率产生间接影响,其影响的净效应取决于两种影响的方向与大小。随后,文章构建由经济增长方程、环境技术进步方程和生态效率方程共同组成的动态面板模型,采用2000~2012年我国省际数据进行实证分析,结果表明:外商直接投资不仅能够直接提高生态效率,还能够提高经济增长和环境技术进步间接提高生态效率,后者的效应大于前者,并且各区域的影响效应存在空间异质性。
The article examines the impact of FDI on the ecological efficiency of our country, that FDI has a direct impact on ecological efficiency, but also indirectly through the promotion of economic growth, environmental and technological progress have an indirect effect on ecological efficiency, the net effect of its impact depends on two kinds of effects The direction and size. Subsequently, the article builds a dynamic panel model composed of economic growth equation, environmental technology progress equation and ecological efficiency equation, and uses the provincial data from 2000 to 2012 for empirical analysis. The results show that FDI can not only directly improve ecological efficiency, But also increase the ecological efficiency indirectly through economic growth and technological progress of environment. The latter has more effects than the former, and the spatial heterogeneity of the regional impact effects.
