This is the comprehensive implementation of urban and rural development to increase industrial agriculture, move the city to support the countryside, accelerate urbanization and narrow the gap between urban and rural areas. To solve the ＂three rural issues＂, the comprehensive construction ofa well-offsociety, has a very important strategic role to ease the contradiction of China＇s rural and urban ecnomic structure. In the process of building a new socialist countryside, the financial policy, as an important means ofmacroeconomic regulation and control, should play a leading role in solving the effective allocation ＆funds. Due to various factors affected by the current supply of rural financial market constraints, system defects and environmental constraints, there is a large gap between the level of the existing rural financial services and the requirements of the new rural construction which is to be improved urgently.展开更多
