To explore the policy effect and the mechanism of well-facilitated farmland construction on green utilization of cultivated land,this paper provides a science reference for realizing the green utilization of cultivated land.Based on a panel data of 30 provinces in China,this paper estimates the policy effect and the mechanism of well-facilitated farmland construction on the green utilization of cultivated land by the continuous difference-in-differences model.Results show that:1)the well-facilitated farmland construction had a significant effect on green utilization of cultivated land,and the robustness test also confirmed the reliability of results;2)the effects of well-facilitated farmland construction on green utilization of cultivated land in dry,paddy and main non-grain producing areas were more significant;3)the well-facilitated farmland construction helps the realization of green utilization of cultivated land by adjusting the planting structure and upgrading the level of agricultural mechanization.Therefore,to continuously promote the implementation of well-facilitated farmland construction policies,this paper suggests:enhancing the post-construction management and maintenance of high-standard farmland,focusing on cultivated land conservation while improving agricultural productivity,improving protection policies for primary grain-producing areas according to the specific types of land,preserving the ecological environment in ecologically fragile areas to prevent over-cultivation,improving the coordination of factor allocation and the green utilization of cultivated land,and encouraging the specialization in grain cultivation,centralized and continuous cultivation,and elevation of comprehensive operation level of agricultural machinery.
