摘　　要：【目的】土地流转作为农业生产集聚和适度规模经营的重要推动力,是否能实现节能减排,关系到中国农业绿色化转型发展战略的有效实施。探究土地流转的节能减排效应及其内在机制,旨在为中国深化农村土地制度改革和实现节能减排目标提供重要参考依据。【方法】基于2005—2021年中国30个省份面板数据,运用广义动态空间模型和中介效应模型,探讨土地流转的节能减排效应及其内在机制。【结果】①土地流转显著抑制农业碳排放,即土地流转具有较好的减排效应;能源消耗是引起农业碳排放增长的重要来源,而土地流转能通过降低能源消耗来抑制农业碳排放,即土地流转发挥了显著的节能效应;②土地流转能通过促进农业生产集聚来推动节能减排;③进一步分析发现,粮食主产区、胡焕庸线东南侧地区的土地流转表现出显著的减排效应,产销平衡区、胡焕庸线西北侧地区的土地流转表现出显著的节能效应;④土地流转的节能减排效应只在适度经营规模内得以呈现,经营规模过大或过小均不利于节能减排效应的实现。【结论】在推动土地流转的过程中要重视降低农业能源消耗的政策举措,并充分考虑地区之间的差异性,加快农业生产集聚,并推动农业适度规模经营。[Objective]As an important driving force for agricultural production agglomeration and operation at moderate scales,the effects of land transfer on achieving energy saving and emission reduction is related to the effective implementation of China’s agricultural green transformation.Exploring the effects of land transfer on energy saving and emission reduction and its underlying mechanisms can provide an important reference for deepening rural land system reform and achieving energy saving and emission reduction goals.[Methods]Based on the inter-provincial panel data from 2005 to 2021,this study used the generalized dynamic spatial model and the intermediary effect model to analyze the effect of land transfer on energy saving and emission reduction and its underlying mechanism.[Results](1)Land transfer significantly inhibited agricultural carbon emissions,indicating that it has an emission reduction effect;Energy consumption is an important source of agricultural carbon emissions,and land transfer can curb agricultural carbon emissions by reducing energy consumption,which means that land transfer also has an energy-saving effect;(2)Land transfer can promote energy saving and emission reduction by promoting agricultural production agglomeration;(3)Further analysis revealed that land transfer in the main grain producing areas and the southeastern side of the Hu Huanyong Line showed significant emission reduction effects,while land transfer in the production-marketing balance areas and the northwestern side of the Hu Huanyong Line showed significant energy-saving effects;(4)The energy saving and emission reduction effects of land transfer only occurred at moderate operating scales,and too large or too small operating scale is not conducive to the realization of energy saving and emission reduction effects.[Conclusion]In the process of promoting land transfer,it is necessary to attach importance to policy measures that reduce agricultural energy consumption,fully consider regional differences,accelerate agricultural
