Abstract: Based on the data of China Labor Force Dynamic Survey (CLDS), this paper uses PSM-DID method to set up panel sorting and binary selection model to analyze the impact of “Separation of Three Rights” and agricultural subsidies on agricultural mechanization. The results show that the policy of “Separation of Three Rights” represented by DID items and agricultural subsidies have significant positive effects on agricultural mechanization. The “Separation of Three Rights” of contracted land mainly acts on agricultural mechanization by enhancing the marginal effects of cultivated land transfer, agricultural production specialization, loans from formal financial institutions, tractor and large-scale agricultural machinery amount. The influence mechanism of agricultural subsidies on agricultural mechanization is mainly reflected in that it enhances the marginal effects of cultivated land transfer, tractor and large agricultural machinery amount. There are some regional differences in the impact of “Separation of Three Rights” of contracted land on agricultural mechanization, but the impact of agricultural subsidies on agricultural mechanization is consistent with the whole country in the eastern, central and western regions. Income from agricultural production and operation, investment in agricultural production, self-owned and transferred land area, size of agricultural labor force, number of tractors and large-scale agricultural machines and tools, education level of heads of households, health level and political profile have significant positive effects on agricultural mechanization.
