江苏省经济发展与水环境污染关系的实证研究

Empirical Research on the Relationship Between Economic Development and Water Pollution in Jiangsu Province

选取了江苏省2000-2013年人均地区生产总值作为经济发展评价指标,选取了工业废水排放量、城镇生活污水排放量、农业面源污染作为水环境污染评价指标,并运用EVIEWS统计软件构建了反映江苏省经济发展和水环境污染之间关系的环境库兹涅茨曲线模型。基于相应的环境库兹涅茨曲线模型,分析了江苏省经济发展和水环境污染之间存在的关系。结果表明：工业废水排放量、城镇生活污水排放量、农业面源污染这三个水环境污染评价指标和江苏省人均地区生产总值之间均呈现出＂倒U型＂的曲线关系,其中城镇生活污水排放量随着当前经济的增长而增多,工业废水排放量和农业面源污染将随着经济的增长而逐渐减少。

This paper firstly selected Jiangsu Province＇s per capita GDP as economic indicator,and selected industrial wastewater discharge,domestic sewage discharge and agricultural non- point source pollution as water pollution indicators from 2000 to 2013. Then statistical software was used to build the corresponding Environment Kuznets Curve model. On the basis of the Environment Kuznets Curve model,this paper analyzed the relationship between economic development and water pollution in Jiangsu Province. The results showed that the relationship of water pollution indicators and per capita GDP appear ＂inverted U＂curve. As the economy grows,the discharge of domestic sewage will increase,while the emission of industrial wastewater and agricultural non-point source pollution will gradually improve.
