环境库兹涅茨曲线研究——基于生活污染和空间计量方法

Study on the Environmental Kuznets Curve: Based on Pollutions from Daily Life and Spatial Econometric Approach

环境库兹涅茨曲线是环境经济学中的一个经典假说,大部分的研究假定污染排放不受相邻国家或地区的影响。基于中国1998-2007年省级生活污染排放数据,使用空间计量方法对EKC模型进行实证分析,结果显示:中国生活污染排放的空间依赖关系并不显著;同时,人均生活污水、人均生活污水中COD和人均生活SO2排放量与人均GDP之间为"倒U型"曲线关系,人均生活烟尘排放量与人均GDP之间为"倒N型"曲线关系,这说明就生活染污而言,中国的经济发展与环境改善是相互协调的。

The Environmental Kuznets Curve is a classic hypothesis in environmental economics, but in most papersit is assumed that emissions are unaffected by events in neighboring states. This paper tests the Environmental Kuznets Curve models based on pollutants from daily living by use of spatial econometric approaches and Chinese panel data set of yearly observations covering 30 provinces and the time period 1998- 2007. The results show that spatial dependenoe in pollution emission data of daily living is not significant. At the same time, it is found that an inverted- U-shaped curve exists between per capita waste water emissions/sulfur dioxide emissions/COD emissions of waster water from daily living and per capita C-DP, and inverted- N- shaped relationships are founded between per capita dust emissions of daily living and per capita GDP, which means economic growth in China is compatible with environmental improvement as far as pollutants from daily living is concemed.
