It is of great significance to improve the financial agglomeration degree and enhance the financial radiation ability to transform the economic growth pattern and push ecological civilization to a new stage.The panel data of 30 regions in China from 2000 to 2017 is used to measure the financial potential energy and ecological efficiency respectively by using the gravity model and entropy method, and the influence of financial potential energy on ecological efficiency is studied by using the Spatial Durbin Model. The financial potential energy and ecological efficiency both have a distribution of "east high - west low" and a positive spatial autocorrelation. Financial potential energy has not only significantly improved the local ecological efficiency, but also existes spillover effect on surrounding areas for it’s positive direct and indirect coefficients. In addition, economic development, industrial structure and pollution control can also improve ecological efficiency, while urbanization acts as a disincentive. Finally, based on the research results, some suggestions such as narrowing regional gap, expanding regional cooperation, developing green finance, and supporting financial innovation are put forward.
