摘要
“双碳”背景下,学者愈发关注数字经济对农业碳排放的抑制效用。本文采用2013—2019年我国31个省份的面板数据,通过运用双向固定效应模型和动态两步系统广义矩估计,构建调节效应模型以探究我国数字经济、农业产业集聚对农业碳排放强度的抑制机理及其效应。研究结果表明:数字经济的发展对农业碳排放强度具有显著抑制作用;构建的数字经济发展指数与农业产业集聚水平交互项为负,证明提高农业产业集聚水平有助于强化数字经济发展对农业碳排放强度的抑制作用;以表示农业产业集聚的区位熵是否大于1为标准进行异质性分析,结果显示:在区位熵大于1的地区,数字经济对农业碳排放强度的抑制作用更为显著。厘清数字经济对农业碳排放强度的影响机理,可为我国农业低碳可持续发展提供路径参考,对我国农业现代化转型具有重要意义。
Under the background of“dual carbon”,scholars are paying more and more attention to the inhibition effect of digital economy on agricultural carbon emissions.The results show that the development of digital economy has a significant inhibitory effect on agricultural carbon emission intensity.The interaction term between the constructed digital economy development index and the agricultural industry agglomeration level is negative,which proves that improving the agricultural industry agglomeration level is conducive to strengthening the inhibition effect of digital economy development on agricultural carbon emission intensity.According to the heterogeneity analysis based on whether the locational entropy representing agricultural industrial agglomeration is greater than 1,the results show that the digital economy has a more significant inhibitory effect on agricultural carbon emission intensity in regions with locational entropy greater than 1.Clarifying the impact mechanism of digital economy on agricultural carbon emission intensity can provide a path reference for the low-carbon sustainable development of China’s agriculture,and is of great significance for China’s agricultural modernization transformation.
