China’s rural social trust relation shows differential order and further the differential order governance mechanism is emerged. In the practice of farming land transfer, the transfer contract has an oral informal and written formal two ways, the farmer households’ choice for the contract way is affected by its association degree between all kinds of trading main bodies and is the result of differential order governance. By using 1628 farmer households spot-survey data in Jiangxi and Liaoning provinces, based on the analysis of structural equation model, this paper analysis results show that when the rural land is transferred between relatives or between friends, more farmer households use non-market-oriented mode (social relation) and have oral informal contract, however, when rural land is transferred between a farmer household and an enterprise or a farmer household of another village, more farmer households use market-oriented written formal contracts. The governments should not use administrative order and so on to forcefully use written formal contract to transfer the land but should actively explore rural land transfer methods based on the reality so as to create good institutional environment for rational and ordered rural land transfer.
