江苏省水污染、环境规制与高质量经济发展

利用江苏省2005—2017年的面板数据,研究水污染、环境规制与高质量经济发展之间的关系。首先采用熵权法构建高质量经济发展评价体系;其次采用SYS-GMM法构建基准回归模型;接着以水污染为门槛变量,研究水污染不同程度下,水环境规制对经济发展的效应;最后,从苏南、苏中、苏北3个区域出发研究水环境污染的空间异质性。研究结果表明:水污染对经济发展质量产生负向效应。江苏省的水环境规制总体上看对经济发展质量产生制约作用。随着水污染程度的加重,环境规制对经济发展质量的抑制作用将逐渐减弱。江苏省三大区域的水污染、环境规制对经济发展质量的影响具有空间异质性。

Water pollution, environmental regulation and high-quality economic development in Jiangsu Province

Using the panel data in Jiangsu Province from 2005 to 2017, the relationship among water pollution, environmental regulation and high-quality economic development is studied. Firstly, the entropy weight method is used to establish the evaluation system for high-quality economic development. Secondly, the SYS-GMM method is used to establish the benchmark regression model. Taking the water pollution as the threshold variable, the effects of water environment regulation on the economic development are investigated under different water pollution levels. Finally, the spatial heterogeneity of water pollution is studied from the south, middle and north regions of Jiangsu Province. The research results show that the water pollution has a negative effect on the quality of economic development. The water environment regulation in Jiangsu Province generally restricts the quality of economic development. With the aggravation of water pollution, the restraining effects of environmental regulation on the quality of economic development will gradually decrease. There is spatial heterogeneity in the influences of water pollution and environmental regulation on the quality of economic development in the three regions of Jiangsu Province.
