碳中和目标下水环境污染与生态经济的关系研究——以江苏省为例

Study on the relationship between water pollution and ecological economy under carbon neutral target:Taking Jiangsu Province as an example

碳中和目标要求贯彻新发展理念,推动高质量发展,其中水环境生态与经济发展具有重要的关联性。以江苏省为例,通过主成分分析法选取该省具有显著代表性的水环境污染指标,以环境库兹涅茨曲线(EKC)为理论基础,构建该省水环境污染与生态经济之间的计量模型。结果表明,江苏省水环境污染与生态经济之间的关系模型均呈非典型的EKC曲线形态,且水环境农业污染源明显强于工业污染源。面对这一态势,应采取有针对性的水环境污染治理举措,实现水环境治理与生态经济发展的良性循环。

The goal of carbon neutrality required the implementation of a new development concept and the promotion of high-quality development,in which water environment ecology and economic development had an important correlation.Taking Jiangsu Province as an example,principal component analysis was used to select significant representative water environmental pollution indicators in the province.Based on the environmental Kuznets curve(EKC),the econometric model between water environmental pollution and eco⁃logical economy of Jiangsu Province was built.The results showed that the relationship models between water pollution and eco-econo⁃my in Jiangsu Province all presented an atypical EKC curve shape,and the agricultural pollution source was obviously stronger than the industrial pollution source.In the face of this situation,it should be taken targeted measures to control water environmental pollu⁃tion and realize a virtuous cycle of water environmental control and ecological economic development.
