Abstract: To judge the direction of agricultural land system reform in China,it's necessary to clarify the theoretical logic of agricultural land system transformation in China.The transformation of agricultural land system can be understood as the differentiation and combination of various rights and functions that constitute the bundle of agricultural land property rights among different subjects since the founding of the PRC:After the land reform at the beginning of PRC,farmers had a complete bundle of agricultural land property rights,but the collectivization of agriculture made the agricultural land property rights defect.The establishment of the household responsibility system has transferred the complete rights of use and usufruct to farmers again,and nowadays the reform of “separation of three rights” is still directed at the complete bundle of agricultural land property rights.The differentiation and combination of various rights and functions of agricultural lands in China reflect the people-centered value orientation of the Communist Party of China.The practice has also proved that the vitality of agricultural production will be released whenever the state or collective grants a certain right to farmers;the vitality of agricultural production will be affected whenever a certain right is withdrawn.Therefore,the theoretical logic of agricultural land system transformation in China can be summarized as adherence to the people-centered value concept and constantly pushing farmers' agricultural land property rights toward the state of the complete bundle of rights.
