The ten relationships during land circulation are discussed. Among them, the relationship between peasant household and government indicates that government should only carry out its service and regulatory functions and farmers should be the main body of land circulation, because peasants usually have no discourse power during land circulation. In the relationship between land ownership and contracting management right, we mainly discuss the transfer of land contracting management right and point out that land contracting management right within a certain period is the object of land circulation. In the relationship between land circulation and deepening reform, land circulation is only an approach to develop scale management and to deepen the reform. Land circulation can be accelerated only by vigorously developing secondary and tertiary industries and speeding up the transfer of rural surplus labor force. In the relationship between land circulation and land reform, it is pointed out that China at present is not suitable for a new land reform. In the relationship between the land contract with time limit and the contract system and private ownership system, contract system and private ownership system are unsuitable for China at present; and we should continue to insist on the land contract with time limit. In the relationship between land circulation and economic development, land circulation is a natural process without enforceability. Otherwise, it may hinder the development of rural economy. In the relationship between enterprise and peasant household, land circulation should be held among peasants and companies and enterprises can participate in it. The relationship between land circulation and agriculture business performance points out that land circulation should adapt to the local situation. Relationship between land circulation and land loss and annexation shows that land circulation must adhere to the moderate principle and prevent land loss of peasants into a handful of persons. And the relationship between small peasant economy and agricultural modernization indicates that economic model of small peasant economy may not be an obstacle to the modernization of agriculture.
