中国数字经济发展对农业碳排放的效应影响

The Influence of China's Digital Economy Development on Agricultural Carbon Emissions

科学评价数字经济对农业碳排放的影响效应,有助于依托数字经济赋能农业碳减排,为我国农业高质量发展和顺利实现“双碳”目标提供有力支持。综合测度2015—2020年中国30个省、市的农业碳排放水平与数字经济发展水平,并在此基础上运用双向固定效应模型和空间杜宾模型检验数字经济发展对农业碳排放的影响及其空间溢出效应。研究结果表明:数字经济发展对我国农业碳排放具有倒U型的非线性影响,这一影响也具有空间溢出特点;异质性分析发现,数字经济对农业优化发展区的碳排放具有显著倒U型影响。

Scientific evaluation of the impact of the digital economy on agricultural carbon emissions is helpful to enable agricultural carbon emission reduction relying on the digital economy,and provides strong support for the high-quality development of China's agriculture and the smooth realization of the"double carbon"goal.This paper comprehensively measures the level of agricultural carbon emissions and the development level of digital economy in 30 provinces and municipalities in China from 2015 to 2020,and then tested the impact of digital economy development on agricultural carbon emissions and its spatial spillover effect by using two-way fixed effect model and spatial Durbin model.The results show that the development of digital economy has an inverted U-shaped nonlinear effect on China's agricultural carbon emissions,which also has the characteristics of spatial spillover.Heterogeneity analysis shows that digital economy has a significant inverted U-shaped effect on carbon emissions in agricultural optimized development areas.
