| 摘 要： | 【目的】农业碳排放问题对于碳达峰碳中和目标实现具有重要意义，农地流转是重大农业变革，对农业碳排放具有显著作用，然而现有研究未深入探索农地流转对农业碳排放的影响，影响了农业碳减排工作的进一步推进。【方法】本文在理论探讨基础上结合2005—2020年中国30个省份面板数据，综合利用双固定效应回归模型、工具变量模型、中介效应模型、空间计量模型，在严格检验基础上实证分析了农地流转对农业碳排放的影响效应、中介路径及其空间特性。【结果】①农地流转对农业碳排放产生显著正向影响，即农地流转面积扩大会促进农业碳排放增加；②农业经营规模在农地流转促进农业碳排放增加过程中发挥部分中介效应，农地流转能通过提升农业经营规模进而增加农业碳排放；③考虑空间效应时，农地流转对本地区农业碳排放产生显著正向影响，对邻近地区农业碳排放产生显著负向影响，农业经营规模在农地流转对本地区农业碳排放的影响过程中发挥部分中介效应。【结论】农地流转对农业碳排放存在显著影响，农地流转推进过程应重视农业碳排放问题。

| Abstract: | Objective] In-depth analysis of the carbon emission effect of rural land transfer is absent in existing studies. Therefore, this study systematically analyzed the influence of rural land transfer on agricultural carbon emissions and its mechanism. Methods] This article first discussed rural land transfer and its potential influence on carbon emissions. Then by using the 2005-2020 provincial panel data of China’s mainland and the two-way fixed effects regression model, instrumental variable model, mediation effect model, and spatial econometric model, it empirically analyzed the effect of rural land transfer on agricultural carbon emissions, its intermediary pathways, and spatial characteristics on the basis of strict tests. Results] The results show that: (1) Rural land transfer overall promotes the increase of agricultural carbon emissions; (2) The scale of agricultural operation has some mediation effect in the process of rural land transfer promoting the increase of agricultural carbon emissions. That is, rural land transfer can have a positive impact on agricultural carbon emissions by improving the scale of agricultural operation; (3) When considering the spatial effect, rural land transfer has a significant positive impact on agricultural carbon emissions in the home region and a significant negative impact on agricultural carbon emissions in neighboring regions. The scale of agricultural operation has a partial mediation effect in the process of rural land transfer influencing agricultural carbon emissions in the home region. Conclusion] Therefore, we should pay attention to the carbon emission reduction work in the process of rural land transfer and promote the inter-provincial agricultural cooperation in emission reduction. |
