Improving rural financial service system is an important part of enhancing high-quality rural financial supply，which is of great significance for strengthening rural revitalization of financial services. China has basically built a multi-level and widely covered rural financial organization system，product system and financial infrastructure system. However，along with the economic development，China’s rural financial needs have changed greatly，and the existing rural financial service system still has room for improvement，resulting in difficulties in matching the financial needs of rural economic and social development at a high level. In the context of rural revitalization，it is necessary to further deepen the reform of rural financial service system by starting with the organizational system，product system and policy guarantee system，develop the rural financial service organizational system in a balanced way，innovate the rural financial product system in a targeted way，and improve the financial infrastructure system to improve the ability of financial service to rural revitalization.
