数字经济与能源消费结构:内在机制与实证检验

Digital Economy and Energy Consumption Structure:Intrinsic Mechanism and Empirical Test

基于中国2011—2022年30个省(自治区、直辖市)的面板数据,考察数字经济对能源消费结构的影响效应和作用机制。研究发现,数字经济能够显著优化能源消费结构,且该优化作用具有边际递减趋势和空间溢出效应。产业结构升级与绿色技术创新是数字经济发挥作用的主要传导机制。在产业结构升级机制中,产业结构高度化比产业结构合理化起的作用更大;在绿色技术创新机制中,实质性绿色技术创新起主要作用。数字经济的优化作用在不同的政府干预程度和环境规制强度下存在差异。为加快推动能源消费结构低碳转型,政府应持续推动数字经济体系建设、产业结构升级和绿色技术创新,同时加强环境规制力度和跨省跨区能源合作机制。

Based on the panel data of 30 provinces(autonomous regions and municipalities directly under the central government)in China from 2011 to 2022,this study examines the impact effect and mechanism of digital economy on energy consumption structure.The research finds that the digital economy can significantly optimize the energy consumption structure,and this optimization effect has a marginal diminishing trend and spatial spillover effect.Industrial structure upgrading and green technology innovation are the main transmission mechanisms for the digital economy to play a role.In the industrial structure upgrading mechanism,the degree of industrial structure sophistication plays a greater role than the rationalization of industrial structure.In the green technology innovation mechanism,substantive green technology innovation plays a major role.The optimization effect of the digital economy varies under different degrees of government intervention and environmental regulation intensity.To accelerate the lowcarbon transformation of the energy consumption structure,the government should continuously promote the construction of the digital economy system,industrial structure upgrading and green technology innovation,and at the same time strengthen environmental regulation and the inter-provincial and crossregional energy cooperation mechanism.
