Green finance policy is a market means of fi-nance and capital in environmental economic policy,and it is al-so an important measure to achieve high-quality development of regional economy.Based on the panel data of 107 cities in the Yangtze River economic belt from 2007 to 2020,this paper sys-tematically examines the influence effect,functional mechanism and heterogeneity of green finance policy on urban environmental governance efficiency by using econometric methods such as pro-pensity score matching-double difference(PSM-DID)and panel quantile regression.The study found that the implementa-tion of green finance policy has significantly improved the effi-ciency of urban environmental governance in the Yangtze River Economic Belt.This conclusion is still true after dynamic effect test,placebo test,changing sample matching method and other robust methods.The mechanism verification shows that the green finance policy improves the efficiency of urban environmental governance by alleviating resource misallocation,promoting green technology innovation,and optimizing industrial structure.Heterogeneity analysis shows that when the development level of urban green finance is higher,the regional comprehensive strength is stronger and the efficiency of environmental govern-ance is lower,the effect of green finance policy on environmental governance efficiency is more significant.
