摘　　要：探究中国现阶段数字经济对农业绿色全要素生产率的影响和作用机制,为推进农业绿色发展、实现农业高质量发展拓展新路径提供参考。采用EBM-GML生产率指数对中国31个省份2011—2020年农业绿色全要素生产率进行测算,再利用系统广义矩估计模型(GMM)实证检验数字经济对农业绿色全要素生产率的影响。结果表明:(1)31个省份农业绿色全要素生产率呈稳定上升趋势,年均增长率为1%,其增长动力主要来自技术进步;(2)各省份农业绿色全要素生产率的发展水平差异较大,2011—2020年期间有75%的地区年均增长为正值;(3)数字基础设施、农业数字化和农业数字产业化对农业整体绿色发展具有显著正向影响;(4)粮食主产区的数字经济对农业绿色全要素生产率的效应更明显。可见,数字经济的发展能够有效促进农业绿色发展,有必要制定相关策略以提高农业绿色全要素生产率,助推农业绿色高质量发展。Exploring the impact and mechanism of the digital economy on agricultural green total factor productivity,This paper aims to provide a reference for promoting green agricultural development and realizing new paths for high-quality agricultural development.The EBM-GML productivity index is used to measure the agricultural green total factor productivity of 31 provinces in China from 2011 to 2020,and then the system GMM model is used to empirically test the impact of the digital economy on the agricultural green total factor productivity.The results show that:(1)Agricultural green total factor productivity in 31 provinces shows a steady upward trend,with an average annual growth rate of 1%,and its growth momentum mainly comes from technological progress.(2)The development level of agricultural green total factor productivity in each province is relatively different,from 2011 to 2020,75%of the regions had a positive average annual growth rate.(3)Digital infrastructure,agricultural digitalization,and agricultural digital industrialization have a significant positive impact on the overall green development of agriculture.(4)The effect of the digital economy on the green total factor productivity of agriculture is more obvious in major grain producing area.It can be seen that the development of the digital economy can effectively promote the green development of agriculture,and it is necessary to formulate relevant strategies to improve the total factor productivity of agricultural green and promote the green and high-quality development of agriculture.
