Abstract: Based on the data of Zhejiang province in 2002~2016, combined with the relevant theories of EKC model, the relationship between economic growth and environmental pollution was analyzed, and the regression model of industrial waste water discharge and domestic waste water discharge and per capita GDP was constructed. The results show that there is an inverted "U" type EKC curve between industrial waste water discharge and per capita GDP, while the domestic waste water discharge and per capita GDP show a positive "U" type EKC curve. And in the next few years, the discharge of industrial wastewater in Zhejiang Province will continue to decline with economic growth, and the discharge of domestic wastewater will increase with the growth of the economy. The governance of water pollution still has a long way to go, it is advocated that who pollutes who pays, increasing the fines for the discharge of domestic waste water and introducing third-party supervision mechanisms.

Key words: economic growth, water environment pollution, EKC model, Zhejiang province
