数字经济赋能产业绿色低碳转型机制研究——以长江经济带中下游为例

The Driving Mechanism of the Digital Economy on Industrial Green and Low-Carbon Transformation—Evidence from the Middle-Lower Yangtze River Economic Belt

摘要: 数字经济作为我国发展新质生产力的主战场，已成为产业绿色低碳转型的重要动力。基于2014~2023年长江经济带中下游77个城市的面板数据，研究通过构建基准回归模型与中介效应模型，实证检验了数字经济对产业绿色低碳转型的驱动效应。结果表明，数字经济对产业绿色低碳转型具有显著的直接驱动效应，且该效应呈现异质性特征。在区域视角方面，下游地区的驱动效应显著优于中游地区；在城市类型视角方面，其对非资源型城市的促进效应明显强于资源型城市。数字经济通过提高绿色技术创新水平和要素配置效率正向促进产业绿色低碳转型。

Abstract: As the primary engine for developing China’s new quality productive forces, the digital economy has become a pivotal driver of industrial green and low-carbon transformation. Utilizing panel data from 77 cities in the middle-lower Yangtze River Economic Belt (2014~2023), this study employs baseline regression and mediation effect models to empirically examine the digital economy’s driving effects on this transformation. Key findings reveal that there is a significant direct driving effect, exhibiting notable heterogeneity. Regionally, downstream areas demonstrate significantly stronger effects than midstream regions. Non-resource-based cities show markedly greater transformation promotion than resource-based counterparts. Mechanism analysis confirms the digital economy facilitates transformation through dual pathways: enhancing green technology innovation and optimizing factor allocation efficiency.
