Abstract: Family farms cannot develop without financial support. Supply leading is the main mode of financial support for family farms in underdeveloped areas. It promoted the appropriate scale development, specialized production and commercial operation of family farms; meanwhile, it has achieved remarkable results. However, the developmental ecology of family farms in underdeveloped areas has not yet formed. Such behaviors have emerged as serious absence, dislocation and exceeding its powers in financial services. Problems such as financing difficulties, high financing costs and weak financing mechanisms are still widespread. Accordingly, we should take the following steps: (1) Increase the rural financial structural supply, establish the concept of financial inclusion and improve the rural financial market system; (2) Adhere to the Trinity of government, financial institutions and family farms, and improve the rural credit system; (3) Strengthen the construction of rural financial environment and improve the organizational security system.
