数字技术发展对我国资源型城市能源效率的空间溢出效应OACHSSCD

Resource-based cities in China,which have long relied on traditional resource consumption and spatially expansive develop-ment models,face multiple challenges such as monolithic industrial structures and worsening environmental pollution.Therefore enhan-cing energy efficiency is a critical measure for these cities to achieve their ̍dual carbon̍ goals.As an emerging productive force,digital technology is becoming the core driver for improving energy efficiency in resource-based cities.Taking 113 resource-based cities in China over the period of 2011 to 2022 as the research subjects,the study measures their energy efficiency from a dynamic perspective,constructs a regression model,and explores the spatial spillover mechanism through which the development of digital technology devel-opment enhances energy efficiency in China̍s resource-based cities.The findings reveal that:during the study period,energy efficien-cy in China̍s resource-based cities fluctuates slightly,showing an overall gradual decline with significant regional disparities;digital technology development significantly improves energy efficiency within regions,though substantial regional heterogeneity persists,and it exerts a significant positive spatial spillover effect on energy efficiency;further analysis indicates that digital technology development ex-erts relatively pronounced direct effects on energy efficiency in resource-based cities of Northeast and Western regions,while their spa-tial spillover effects are notably pronounced in resource-based cities of Northeast and Eastern regions.
