The Fifth Plenary Session of the 19th CPC Central Committee proposed to speed up the construction of a new development pattern with domestic circulation as the main body and domestic and international double circulation promoting each other. Implementing the strategy of Rural Revitalization is an inevitable requirement for accelerating the construction of a new development pattern of "double circulation". Rural Revitalization is inseparable from financial support. However, there are still some problems in financial support, such as the imperfect diversified rural financial service system, the innovation of agricultural financial products can not meet the development needs, and the construction of rural financial ecological environment lags behind. Based on the analysis and reference of the experience of some foreign developed countries in promoting financial support for rural development, this paper puts forward relevant suggestions on deepening financial support for Rural Revitalization under the new development pattern.
