数字经济赋能“双碳”战略研究——影响机理及实现路径

Digital economy empowers“Dual Carbon”goals:influence mechanism and implementation path

数字经济已成为支撑当前和未来经济发展的重要动力,在“双碳”目标下,探讨数字经济发展能否助力减排对当前经济高质量发展以及生态文明建设都具有重要价值。为验证数字经济与碳排放之间复杂的影响路径,文中采用双向固定效应模型、中介效应模型、门槛效应模型及空间杜宾模型进行实证分析。结果发现:数字经济可以显著抑制碳排放强度和人均碳排放;数字经济可以帮助调整能源结构进而显著减少碳排放;随着能源效率的提高,数字经济与碳排放之间的关系呈现倒“U”型特征;在3种空间距离权重矩阵下,数字经济对碳排放的作用效果展现出空间溢出特征。研究结论为进一步推动数字经济发展、实现“双碳”目标提供了有价值的决策参考。

The impact of carbon emissions is global,posing a threat to global climate,ecological balance,human health and other aspects.Digital economy is being integrated into various fields of economic and social development,and its impact on carbon emissions deserves attention and exploration.In order to verify the complex internal influence path between digital economy and carbon emissions,this study successively adopts the two-way fixed effects model with time and individual effects,the mediation model,the threshold effect model and the spatial Durbin model.The empirical results show that:first,digital economy can significantly inhibit carbon emission intensity and per capita carbon emissions;Second,the digital economy can help adjust the energy structure,thus significantly reducing carbon emissions.Third,with the improvement of energy efficiency,digital economy and carbon emissions show an inverted U-shaped relationship.Fourthly,under three spatial weight matrices,the effects of digital economy on carbon emission show spatial spillover effect.The conclusions of this study provide reference for further promoting the development of digital economy and realizing China’s“Dual Carbon”goals.
