Based on the theory of transaction cost， this paper divides the transaction costs that affect farmland management right transfer into endogenous transaction costs and exogenous transaction costs. The paper respectively analyzes the forming logic of endogenous transaction costs and exogenous transaction costs in the process of farmland management right transfer，and uses the transaction cost model for agricultural products of farmers constructed by Key and so on to discuss how the transaction costs affect the agricultural land transfer， decisionmaking behavior of the transferin party and transferout party， and thus affect farmland management right transfer. In order to solve the problem of excessive transaction costs in the process of farmland management right transfer， this paper envisages the new model of farmland management right transferer， which is coordinated by the government and the market， the three systems linkage and the whole process of service control. The new idea is tested by the model.
