基于生活污染物的环境库兹涅茨曲线

Study of Environmental Kuznets Curve Based on Pollutants from Daily Living

利用中国1998-2007年的省级面板数据，对基于生活污染物的EKC模型进行了实证检验。结果显示：我国的生活SO2、生活烟尘排放量与人均GDP之间不存在长期协整关系；生活污水排放与人均GDP之间的关系呈倒U型的EKC曲线，且处于曲线的上升阶段；生活污水中COD排放量与人均GDP既存在倒U型的EKC曲线关系，也存在N型曲线关系。

The Environmental Kuznets Curve is a classie hypothesis in environmental economies, whieh investigates the relationship between economic growth and industrial pollution mainly. This paper tests the Environmental Kuznets Curve models based on pollutants fi＇om daily living by use of Chinese panel data set of yearly observations covering 30 provinces and the time period 1998 - 2007. The results show that there is no long term balanced relation between sulfur dioxide/dust emissions from daily living and per capita GDP; an inverted- U - shaped relationship between waste water emissions from daily living and per capita GDP which is the upload stage of the EKC. At the same time, it has been found that both an inverted - U - shaped relationship and a N - shaped relationship exist between COD emissions of waster water form daily living and per capita GDP.
