By selecting the relevant data of 30 provinces in China from 2011 to 2020,this paper used the entropy method and ultra-efficient SBM-DEA model to calculate the green finance development index and ecological welfare performance index.It used the Tobit model to empirically investigate the impact of green finance on ecological welfare level.The empirical results showed that the development level of green finance and the level of ecological welfare in China showed a development pattern of “high in the east and low in the central and western regions”,and there were large regional differences.In general,green finance could significantly contribute to the level of ecological welfare performance.
