数字经济对低碳转型的影响机制与提升路径

The Impact Mechanism and Enhancement Pathways of the Digital Economy on Low-Carbon Transformation

摘要: 在“双碳”目标和数字经济大力发展的背景下，探究数字经济对低碳转型的影响机制与提升路径具有重要意义。利用2008~2023年中国31个省级行政单位的面板数据，探讨了数字经济与低碳转型的关系。研究发现：数字经济对低碳转型具有显著正向促进作用，该结论在稳健性检验后仍然成立；中介效应检验表明，绿色技术创新与产业结构升级在数字经济影响低碳转型的路径中发挥部分中介作用；异质性分析表明，无论是东部地区，还是中、西部地区，数字经济对低碳转型均具有显著促进效应；从战略区域维度看，在长江经济带数字经济对低碳转型的促进效应同样显著；政策效应分析表明，“宽带中国”政策实施后数字经济的低碳转型驱动效应显著增强。

Abstract: Against the backdrop of the “dual carbon” goals and the vigorous development of the digital economy, exploring the impact mechanisms and enhancement pathways of the digital economy on low-carbon transformation holds significant importance. Using panel data from China’s 31 provincial-level administrative units spanning 2008 to 2023, this study examines the relationship between the digital economy and low-carbon transition. The findings reveal that the digital economy exerts a significant positive effect on low-carbon transition, a conclusion that remains robust after stability tests. Mediating effect tests indicate that green technological innovation and industrial structure upgrading partially mediate the pathway through which the digital economy influences low-carbon transition. Heterogeneity analysis shows that the digital economy significantly promotes low-carbon transition in both eastern regions and central/western regions. From a strategic regional perspective, the digital economy also significantly promotes low-carbon transformation in the Yangtze River Economic Belt. Policy effect analysis indicates that the low-carbon transformation driving effect of the digital economy significantly strengthened after the implementation of the “Broadband China” policy.
