The Analysis of Supply Problem of Public Products in China;

At the present time,some problems exist in the rural public goods supply of China,such as the deficient supply gross,unbalanced constructure,low efficiency and etc.

It is very important to explore the public goods supply theory consistent with the Chinese reality,because we are in a critical period,which need plan the rural and urban public goods supply as a whole.

Regional economic cooperation mechanism to promote the supply of public goods and countermeasures

The research result shows that the expansion of individual heterogeneity, (preference difference, supply technology difference and endowment difference) benefits the supply of public goods, but the issue of free rides deteriorates with the expansion of the difference.

The gap between urban and rural economic shows a marked wave-type model, and the level of urban-rural gap in the supply of public goods is also growing.
