With the in-depth implementation of the Rural Revitalization Strategy, the optimization of the rural financial service system is particularly critical, which is of great significance in promoting rural economic development and improving the living standards of farmers. At present, the rural economy and the overall economic strength are relatively weak, making it difficult to achieve the goal of promoting rural revitalization comprehensively only through rural finance. Based on this, this paper analyzes the current situation of the rural financial service system and puts forward strategic measures such as strengthening the construction of the service network, innovating financial products and services, and improving the risk prevention and control mechanism. These measures will help to improve the overall efficiency of the rural financial service system, provide strong financial support for rural revitalization, and promote the sustainable development of the rural economy.
