为探究数字经济对碳排放效率的影响,基于我国30个省份2011-2020年的面板数据,采用熵值法测度数字经济发展水平、超效率SBM模型测算碳排放效率,构建双向固定效应模型和动态空间杜宾模型实证分析数字经济发展对碳排放效率的影响及其空间溢出效应.研究发现:我国数字经济发展存在较大的地区和省际差距,东部地区数字经济发展远高于中西部地区;数字经济对碳排放效率的影响呈"倒U型"趋势,并且存在显著的空间溢出效应;数字经济与碳排放效率之间的非线性关系存在区域异质性、资源禀赋异质性及数字经济维度异质性.为实现"双碳"战略目标,应因地制宜制定数字经济发展战略,加强区域协作,实现数字经济与低碳经济融合发展,充分发挥数字经济的碳减排效应.
The Carbon Reduction Effect of Digital Economy Development under the"Dual Carbon"Background
This paper explores the impact of the digital economy on carbon emission efficiency by ana-lyzing panel data from 30 provinces in China between 2011 and 2020.The entropy method is employed to measure the level of digital economy development,while the super-efficiency SBM model is used to calculate carbon emission efficiency.A two-way fixed-effects model and a dynamic spatial Durbin mod-el are constructed to empirically assess the influence of digital economy development on carbon emission efficiency and its spatial spillover effects.The findings reveal significant regional disparities in China's digital economy development,with the eastern region significantly outpacing the central and western re-gions.The relationship between the digital economy and carbon emission efficiency exhibits an inverted U-shaped trend and demonstrates notable spatial spillover effects.The non-linear relationship presents regional heterogeneity,resource endowment heterogeneity,and digital economy dimension heterogene-ity.To achieve the"Dual Carbon"strategic goals,it is recommended to formulate digital economy strate-gies tailored to local conditions,enhance regional collaboration,promote the integrated development of digital and low-carbon economies,and fully leverage the carbon emission reduction effects of the digital economy.
