Abstract: In order to accurately describe the path and formation mechanism of farmland function transformation in China, the theoretical framework and evaluation index system of farmland function transformation were established, and the method of determining index weight based on game theory was proposed. Based on the comprehensive index model, the farmland functional transformation index of China’s provinces from 2000 to 2020 was measured, and the mechanism of farmland transformation in China was analyzed. The results showed that from 2000 to 2020, the social function of cultivated land increased and then decreased, the economic function decreased and then increased, and the ecological function remained stable. Among the sub-functions, the function of food security and ecological function were in the main position, the economic contribution function of cultivated land was stronger in underdeveloped areas, and the social function of cultivated land was stronger in northeast areas. From 2000 to 2020, the change of cultivated land function in China took a turning trend and began to evolve along the development direction of urban and rural residents’ demand. On the whole, the driving force of the urbanization level, the quality of economic development, the proportion of non-agricultural industry and the difference in the central, eastern and western areas on cultivated land function transformation had reduced, the driving force of regional economic aggregate on cultivated land function had increased, and the influence of population density on cultivated land function had remained stable.
