本文通过搜集我国2000-2014年的中部地区的相关数据构建固定效应模型,对经济发展水平与污染减排的关系进行了实证研究。实证结果表明,人均产出与三种环境污染指标之间呈现显著的倒“U”型关系,验证了EKC假说。由此说明经济发展水平是影响污染减排的主要因素,经济发展水平应如何调整以实现污染减排成为关注的焦点。
This paper builds a fixed effect model by collecting relevant data in the central region of China from 2000 to 2014 and makes an empirical study on the relationship between economic development and pollution reduction. The empirical results show that the per capita output and the three kinds of environmental pollution indicators showed a significant inverted “U ” type relationship, validated the EKC hypothesis. This shows that the level of economic development is the main factor affecting the pollution reduction, how to adjust the level of economic development to achieve pollution reduction become the focus of attention.
