中国环境库兹涅茨曲线的实证分析

An empirical analysis of environmental Kuznets curve in China

环境库兹涅茨曲线是衡量环境污染与经济增长的重要指标之一,本文采用我国31个省、市、自治区环境、经济的面板数据,分析环境污染与经济增长的关系。结果发现,废水和经济增长之间的关系呈现"倒U型",拐点出现在人均收入2.7万元左右,但废气与经济增长之间关系亦呈现"倒U型",拐点出现在人均收入8.8万元左右。说明我国废水治理较早,技术较为成熟,但废气治理尚需加强。

Environmental Kuznets Curve is an important indicator of the relationship between environmental pollution and economic growth. This paper uses China's 31 provinces and autonomous regions of the economic environment of panel data regions,analyzed the relationship between environmental pollution and economic growth. The results showed that the relationship between wastewater and economic growth in the 'inverted U' inflection point,the per capita income of about 27 thousand yuan,but also the relationship between the gas and the economic growth present the 'inverted U' inflection point in per capita income 88 thousand yuan. This shows that China's wastewater treatment earlier,more mature technology,but the waste gas treatment still need to strengthen.
