摘　　要：数字经济在蓬勃发展的同时表现出碳减排效应。理论上,数字经济可以通过提升农业全要素生产率,从而赋能农业碳减排。实际操作中,利用熵值法测度了2014—2020年中国30个省份农业农村数字经济发展指标,利用中介模型分析农业全要素生产率在数字经济影响农业碳排放的过程中的中介效应。在此基础上进行计量分析结果表明:中国农业数字经济蓬勃发展的同时呈现出区域发展不均衡态势,东部的农村数字经济发展水平高于中西部。数字经济能够显著降低农业碳排放强度,但是这种减排效应具有明显的区域差异,西部地区减排效果明显优于东部和中部地区。数字经济在降低农业碳排放强度的过程中,农业全要素生产率发挥了部分中介效应,中介效应占比为31.1%。这一结论在进行一系列的稳健性检验后仍然成立。The digital economy is booming while showing carbon reduction effects.In theory,the digital economy can empower agriculture to reduce carbon emissions by improving agricultural total factor productivity.In practice,this paper uses the entropy method to measure the agricultural and rural digital economy development indicators of 30 provinces in China from 2014 to 2020,and uses the mediation model to analyze the mediation effect of agricultural total factor productivity in the process of digital economy affecting agricultural carbon emissions.On this basis,the econometric analysis results show that while China’s agricultural and rural digital economy is booming,but it shows an uneven regional development,and the development level of rural digital economy in the east is higher than that in the central and western regions.The digital economy can significantly reduce the intensity of agricultural carbon emissions,but this emission reduction effect has obvious regional differences,and the emission reduction effect in the western region is significantly better than that in the eastern and central regions.In the process of reducing the carbon emission intensity of agriculture in the digital economy,the total factor productivity of agriculture has played a partial intermediary effect,and the intermediary effect accounted for 31.1%.This conclusion still holds after a series of robustness tests.
