Green mountains are golden mountains and silver mountains. In the context of seeking high-quality economic development, we should maintain the dynamic balance between economic development and ecological environment. Based on the panel data of 31 provinces in China from 2010 to 2019, referring to battese and coelli's model, this paper uses the latest stochastic frontier approach method to calculate total factor productivity. The study found that green finance and research and development investment can significantly promote high-quality economic development, and green finance can promote economic growth by strengthening research and development investment. Through the sub regional research, it is found that the eastern region has the largest pulling effect on economic growth, the western region has an indirect promoting effect, while the economic growth effect of green finance in the central region has not yet appeared; Technology research and development only significantly promoted economic growth in the eastern and western regions. This shows that in today's slow economic growth and serious degradation of the ecological environment, the development of green finance is an important strategy to protect the ecological environment and promote sustainable economic development.
