摘要: 本文提出采用聚类分析克服环境库兹涅茨曲线的“同质”假设,并根据城乡混合基尼系数对人均GDP进行调整,利用1991-2009年29个省市的面板数据对我国经济增长与环境污染之间的关系进行了分析。结果表明:我国环境污染与经济增长的关系形式具有多样性,对同种污染物进行全国层面的估计及对不同污染物采用相同的分组模式都会产生较大的误差。另外,调整后的人均GDP与污染物的估计结果印证了收入差距过大会导致环境库兹涅茨曲线拐点右移的假说。产出方程则表明了环境污染对经济增长的抑制作用,并且单位环境污染的反作用要强于其他单位要素对经济的促进作用,同时同种要素投入对不同组别的经济促进作用也不尽相同,最后提出了相应的政策建议。

Abstract: This paper proposes using clustering to overcome the homogeneous assumption of Environmental Kuznets Curve and according to the mixture gini coefficient to adjust the per capita GDP to analysis the relationship between economic growth and environmental pollution by use of Chinese panel data set of yearly observations covering 29 provinces and the time period 1991-2009.The results shows that: Environmental pollution and economic growth has a variety of forms, estimating the same pollutants with the national level and different pollutants in the same triage mode will produce a great error. In addition, the results between the adjusted per capita GDP and pollutants support the hypothesis that income gap can cause the turning point of EKC to move right. The output equation shows the inhibition of environmental pollution to economic growth, and the reaction of unit environmental pollution greater than any other factors to impetus the economic. Also the same elements have a different promotion to different groups, at last presents the corresponding policies.
