利用1992~2011年我国省际面板数据,通过主成分分析法构造环境污染综合指标,进而建立面板数据模型,实证分析了经济增长对环境污染的影响及区域性差异,并讨论了环境污染治理投资、技术进步、人口、储蓄率、产业结构和贸易开放度等因素对环境污染的影响。实证结果发现,从全国范围来看,经济增长对环境污染的影响符合环境库兹涅茨曲线假说,且目前已处于倒u型曲线的下降部分;东部地区和中部地区同样存在倒u型关系并处于其下降部分,西部地区呈现出n型关系并处于右侧上升部分。同时,不同控制变量对环境污染的影响也具有不同特点。This paper empirically investigates the influence of economic growth to environmental pollution and regional heterogeneity.We also discuss the influence of other factors to environmental pollution, including abatement investment, technology, population, saving rate, industrial structure and trade openness.Empirical results suggest that the effect of economic growth to environmental pollution copes with the Environmental Kuznets Curve from the perspective of the whole nation, laying on the right downward part of the inverted-U curve.From regional perspective, there also exists inverted-U shaped curve in the eastern and middle regions while in the western region the relationship appears to be N shaped.Meanwhile, the influence of other factors displays distinct characteristics
