我校经济管理学院易明老师在T1级别期刊——《Energy Policy》上发表题为“Effects of digital economy on carbon emission reduction: New evidence from China”。论文第一作者易明为经济管理学院教授,博士生导师。

文章利用2011-2019年中国省际面板数据,构建空间面板杜宾模型和中介效应模型,实证考察数字经济对碳减排的作用机制和影响效应。研究结果发现:①中国数字经济发展具有显著的碳减排效应,且该效应具有空间溢出性;②数字经济对碳减排存在直接和间接两种影响机制,数字经济可以通过改变能源结构而间接影响碳排放;③数字经济的碳减排效应具有区域异质性,表现为碳减排效应在中国东部地区较为明显,而在中部、西部及东北地区则并不显著。上述结论为政策制定者提供了推动数字经济发展,加大各地区数字基建协调力度,重点发展能源数字经济的新证据,能够为发展中国家以数字经济驱动碳达峰、碳中和提供经验借鉴。

Abstract / 摘要:

原文 Recently, the progress of reaching carbon emission peaks and achieving carbon neutrality has had significant impacts on the global economy. The overall societal efforts on carbon emission reduction from various industries will likely be strengthened, thanks to the advantages enterprises could gain in digital technologies through a structural upgrade in the energy systems. Based on China's provincial panel data from 2011 to 2019, this paper constructs a spatial panel Durbin model and a mediating effect model to investigate the mechanism and influence of the digital economy on carbon emission reduction. The results show that (1) the development of the digital economy has a significant spatial spillover effect on carbon emission reduction; (2) the digital economy influences carbon emission reduction both directly and indirectly. This means that the carbon emission reduction can be affected indirectly by the digital economy through the transformation of energy structure; (3) the carbon emission reduction effect of the digital economy exhibits regional heterogeneity, it is more prominent in eastern regions than in other areas. The above findings provide substantial empirical evidence to policymakers on how to best promote the development of the digital economy and intensify the coordination of China’s digital infrastructure in regional environmental governance.
