摘　　要：农业是二氧化碳等温室气体的重要排放来源,发展低碳农业、降低农业碳排放是实现中国碳达峰、碳中和目标的重要路径,因此农业碳排放效率研究具有重要的实践价值和战略意义。研究选取安徽省16市2011—2020年的面板数据,利用SBM-DEA和Malmquist模型,对安徽省各市农业碳排放效率进行测算,并采用σ收敛测算变异系数对安徽省农业碳排放效率变动趋势进行分析。测算结果表明:安徽省总体农业碳排放量呈现先增后减的倒U型趋势,自2016年后低碳农业发展水平显著提升;安徽省农业碳排放效率整体水平较高,但区域发展不平衡,地区发展差异大,且各市农业碳排放效率水平差异逐年增大,呈离散态势。未来应进一步提高政策支持力度、发展低碳农业技术、加强农业碳减排宣教和搭建区域合作平台,发展低碳农业,提高碳排放效率。Agriculture is an important emission source of greenhouse gases such as carbon dioxide.Developing low-carbon agriculture and reducing agricultural carbon emissions is an important path to achieve the goal of carbon peak and carbon neutrality in China.Therefore,the study on agricultural carbon emission efficiency is of important practical value and strategic significance.This paper selects panel data of 16 cities in Anhui Province from 2011 to 2020,uses SBM-DEA and Malmquist model to measure agricultural carbon emission efficiency of each city in Anhui Province,and adoptsσ-convergence to measure variation coefficient to analyze the changing trend of agricultural carbon emission efficiency in Anhui Province.The results show that:overall agricultural carbon emissions in Anhui Province show an inverted U-shaped trend of first increasing and then decreasing,and low-carbon agricultural development has improved significantly since 2016.The overall agricultural carbon emission efficiency in Anhui Province is high,but the regional development is unbalanced and there is large difference in regional development.Agricultural carbon emission efficiency in various cities differs increasingly year by year,presenting a discrete trend.It is suggested to provide policy support,develop low-carbon agricultural technologies,strengthen publicity and education on agricultural carbon emission reduction as well as build regional cooperation platforms to develop low-carbon agriculture and improve carbon emission efficiency.
