摘　　要：绿色农业补贴是激励农业生产主体扩大经营规模和促进农业技术进步继而实现源头防控农田碳排放的重要政策之一,因此评估其降碳效应并厘清传导机制,对实现“双碳”目标具有重大意义。基于2000—2021年中国省级面板数据,借助绿色农业补贴政策改革试点这一准自然实验,构建多期双重差分模型,实证考察了绿色农业补贴政策的降碳效应及其作用机制。结果表明:绿色农业补贴政策显著促进了农业降碳,且该结论通过一系列稳健性检验;机制检验表明,政策的降碳效应通过规模经济效应和技术进步效应两条机制得以实现;异质性分析表明,绿色农业补贴政策的降碳效果在东部地区和农业低污染地区较为明显。因此,政府部门应调整优化政策,总结推广经验;通过实现规模经济、促进技术进步的方式实现碳减排;因时因地制宜,精准分类施策,扎实推进农业绿色发展。Green agricultural subsidies are one of the most important policies to stimulate agricultural producers to expand their scale of operation and promote the progress of agricultural technology so as to realize the prevention and control of carbon emissions from farmland at the source,therefore,it is of great significance to assess the carbon reduction effect and clarify the transmission mechanism in order to realize the goal of“dual-carbon”.Based on China’s provincial panel data from 2000 to 2021,and with the help of a quasi-natural experiment,a multi-period difference-in-differences method is constructed to empirically investigate the carbon reduction effect of green agricultural subsidy policy and its mechanism.The results show that the green agricultural subsidy policy significantly contributes to agricultural carbon reduction,and the conclusion passes a series of robustness tests;the mechanism test shows that the carbon reduction effect of the policy is realized through two mechanisms,namely,the scale economy effect and the technological progress effect;and the heterogeneity analysis shows that the carbon reduction effect of the green agricultural subsidy policy is more obvious in the eastern region and the region with low agricultural pollution.Therefore,the government should adjust and optimize the policy,summarize and promote the experience;achieve carbon emission reduction by realizing economies of scale and promoting technological progress;and implement precise and classified policies according to the time and place,so as to solidly promote the green development of agriculture.
