摘　　要：提出扩展的EKC模型,从经济规模、经济结构和经济强度3个维度,实证研究了经济发展对空气污染影响的省际异质性。研究结果表明:1)约23%的省份不满足EKC模型,且曲线各异:呈双U型、锯齿型、阶梯型等,满足EKC模型的省份,拐点也明显不同。2)经济规模、经济结构、经济强度对空气污染影响的省际异质性均比较大,约19%的省份第二产业占比对空气污染的贡献度远高于其他省,约55%的省份出口贸易变量的系数显著为正。3)3个维度中任一维度的经济发展指标对空气污染的影响均显著,证明了扩展EKC模型的有效性。This paper used an extended EKC model to examine the inter-provincial difference of air pollution from economic scale,economic structure and economic strength. The results suggested that 23% of the provinces did not meet EKC model.The curves of these provinces were different,such as double U shape,zigzag,ladder shape and so on. Provinces which met the EKC model also obviously had different inflection point. Besides the inter-provincial heterogeneity of the impaction of economic scale,economic structure and economic strength on air pollution were relatively large. The secondary industry of about 19% provinces leaded to a more serious air pollution than other provinces. About 55% provinces became foreign pollution heaven. At last,the significance of three economic development indicators proved the validity of the extended EKC model.
