| 摘要: |
| 资源型城市由于长期依赖传统资源消耗和空间扩张型发展模式,面临着产业结构单一、环境污染加剧的多重挑战,提高能源效率是其实现“双碳”目标的关键举措。数字技术作为一种新兴生产力,正成为提升资源型城市能源效率的核心动力。以2011—2022年我国113个资源型城市为研究对象,在动态视角下对其能源效率进行测度,并构建回归模型,探究数字技术发展对我国资源型城市能源效率提升的空间溢出作用机理。研究发现:考察期内,我国资源型城市能源效率略有波动,整体呈缓慢下降趋势,区域间的能源效率差异较大；数字技术的发展显著提升了区域内的能源效率,但存在较大的区域异质性,同时 数字技术对能源效率的影响存在显著的正向空间溢出效应；进一步分析发现,数字技术对东北和西部地区资源型城市能源效率的直接影响相对显著,对东北和东部地区资源型城市的空间溢出效应较为显著。 |

| Abstract: |
| Resource-based cities in China, which have long relied on traditional resource consumption and spatially expansive development models, face multiple challenges such as monolithic industrial structures and worsening environmental pollution. Therefore enhancing energy efficiency is a critical measure for these cities to achieve their 'dual carbon ' 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 development enhances energy efficiency in China 's resource-based cities. The findings reveal that:during the study period, energy efficiency in China 's 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 exerts relatively pronounced direct effects on energy efficiency in resource-based cities of Northeast and Western regions, while their spatial spillover effects are notably pronounced in resource-based cities of Northeast and Eastern regions. |
