摘　　要：为揭示土地财政对农业绿色发展的作用机理及影响效应,探讨在土地财政与城镇化耦合协调发展影响下农业绿色发展能否实现,构建了“土地财政-城镇化-农业绿色发展”理论框架,基于2011—2020年全国30个省级行政区的面板数据,实证分析了土地财政对农业绿色全要素生产率的影响,以及城镇化耦合协调发展系数对上述影响的中介效应。结果表明:土地财政显著推动了农业绿色全要素生产率水平的提高,在土地财政与农业绿色全要素生产率的关系中,城镇化耦合协调发展系数发挥着部分中介作用,并且促进了农业绿色全要素生产率水平提高;土地财政对农业绿色全要素生产率的促进影响呈现区域异质性特征,东中部地区显著,而西部地区不显著。基于此,应该加强土地财政对农业的投入力度和提高城镇化水平,通过资源积聚来提升农业绿色全要素生产率,同时应实行差别化的土地政策,更好发挥财政支农的引导作用。In order to reveal the action mechanism and impact effect of land finance on agricultural green development and explore whether agricultural green development can be achieved under the influence of the coupling and coordination development of land finance and urbanization,a theoretical framework of"land finance-urbanization-agricultural green development"was constructed.Based on the panel data of 30 provincial-level administrative regions in China from 2011 to 2020,this paper empirically analyzes the impact of land finance on agricultural green total factor productivity and the mediating effect of the coupling and coordination development coefficient of urbanization on the above-mentioned impact.The results show that land finance has significantly promoted the improvement of the level of agricultural green total factor productivity.In the relationship between land finance and agricultural green total factor productivity,the coupling and coordination development coefficient of urbanization plays a partial mediating role and promotes the improvement of the level of agricultural green total factor productivity;the promoting impact of land finance on agricultural green total factor productivity shows the characteristics of regional heterogeneity,which is significant in the eastern and central regions but not significant in the western region.Based on this,the investment intensity of land finance in agriculture should be strengthened and the level of urbanization should be improved to enhance agricultural green total factor productivity through resource accumulation.At the same time,a differentiated land policy should be implemented to better play the guiding role of financial support for agriculture.
