China is the largest carbon emitter in the world, with agricultural carbon emissions accounting for 17% of China's total carbon emissions. Agricultural carbon emission reduction has become the key to achieving the "Double Carbon" goal. At the same time, the role of the digital economy in achieving the "dual carbon" goal cannot be ignored as an important engine to boost the high-quality development of China's economy. Therefore, this paper uses the panel data of 30 provinces in mainland China from 2011 to 2019 to construct a spatial Durbin model and a mediation effect model to explore the impact of the digital economy on agricultural carbon intensity and the mediating role of agricultural technological progress. The research results show that: (1) China's agricultural carbon intensity fluctuated and declined during the study period, but the current agricultural carbon intensity is still at a high level; (2) The inhibitory effect of the digital economy on agricultural carbon intensity is achieved by promoting agricultural technological progress, and the intermediary role of agricultural technological progress has been verified; (3) The digital economy can significantly reduce the carbon intensity of agriculture, and this inhibition has a positive spatial spillover effect. According to the research conclusions, the government should speed up the development of internet technology and digital inclusive finance, support agricultural technology research and improve farmers' human capital, and strengthen regional cooperation to release the contribution of digital economy space.
中国是世界上最大的碳排放国,农业碳排放占中国碳排放总量的 17%。农业碳减排已成为实现“双碳”目标的关键。同时,数字经济在实现“双碳”目标中的作用不可忽视,是推动中国经济高质量发展的重要引擎。因此,本文利用 2011-2019 年中国大陆 30 个省份的面板数据,构建空间杜宾模型和中介效应模型,探讨数字经济对农业碳强度的影响以及农业技术进步的中介作用。研究结果表明:(1)研究期间中国农业碳强度呈波动下降趋势,但目前农业碳强度仍处于较高水平;(2)数字经济通过促进农业技术进步来实现对农业碳强度的抑制作用,验证了农业技术进步的中介作用;(3)数字经济可以显著降低农业碳强度,这种抑制作用具有积极的空间溢出效应。根据研究结论,政府应加快互联网技术和数字包容性金融的发展,支持农业技术研究,提高农民人力资本,加强区域合作,释放数字经济空间的贡献。
