摘　　要：利用产出距离函数将农业碳生产率变化分解为技术效率、技术进步和要素替代变化,并实证测算1995—2016年中国农业碳生产率的变化及其驱动因素,结果表明:(1)研究期中国农业碳生产率年均提高3.57%,单位GDP碳排放量年均下降3.31%,累计下降50.96%,主要归因于技术进步和要素替代效应。(2)中国农业资本深化对农业碳生产率提升有正向影响,劳动力价格上涨有负向影响。(3)中国农业碳生产率表现出“东高西低,阶梯分布”的空间特征,东南沿海省份和西北省份存在区域“农业碳生产率缺口”,且呈缺口扩大趋势。鉴于此,为提高农业碳生产率提出政策建议。Using the output distance function,this research decomposes agricultural carbon productivity changes into technical efficiency,technological progress and factor substitution changes,and then it empirically measures the changes in China’s agricultural carbon productivity and its driving factors from 1995 to 2016.The results show that:(1)During the research period,the average annual increase of China’s agricultural carbon productivity is 3.57%,and the carbon emissions per unit of GDP are down by 3.31%annually,with a cumulative decrease of 50.96%,mainly due to technological progress and factor substitution effects.(2)The deepening of China’s agricultural capital has a positive impact on the improvement of agricultural carbon productivity,and the rise in labor prices has a negative impact.(3)China’s agricultural carbon productivity shows the spatial characteristics of“East high and low west,step distribution”.There are regional“agricultural carbon productivity gaps”in the southeastern coastal provinces and northwestern provinces,and there is a gap expansion trend.In view of this,policy recommendations for improving agricultural carbon productivity.
