The main policies that have been introduced are as follows: First, improve and strengthen the services of rural credit cooperatives in supporting agriculture. At present, 92.6% of the country's credit cooperatives have started micro-credit loans for farmers and joint guarantee loans for farmers. The second is to clarify the obligation of financial institutions to serve rural communities. The state requires financial institutions to use a certain proportion of deposits in the county to support the economic development of the county, including supporting farmers to develop production. Third, take effective measures to guide the postal savings funds absorbed at and below the county level to flow back to the countryside. Fourth, under the premise of strict supervision and effective prevention of financial risks, we should encourage qualified places to actively set up financial organizations with various forms of ownership to directly serve agriculture, rural areas and farmers by attracting social capital and foreign capital. Fifth, in view of the fact that it is difficult for farmers and rural small and medium-sized enterprises to guarantee loans, we should explore various forms of guarantee such as chattel mortgage, warehouse receipt pledge and equity pledge.
