| 煤炭资源型城市作为我国重要能源后备基地,准确识别该类城市能源转型水平与障碍因子,不仅有利于我国碳中和目标的实现,更有利于资源可持续利用. 基于熵值-综合指数法对47个煤炭资源型城市2010~2020年的能源转型水平进行评价并诊断障碍因子. 结果表明：①煤炭资源型城市能源转型水平稳步提升,整体趋于多极化发展且城市间差距不断增大；各准则层发展水平存在显著差异；在空间上呈现由以低水平城市为主的“分散式”布局向以较高水平城市为核心的“组团式”形态演变；②从城市类型看,成长型城市的转型水平高于其他类型城市,且城市间转型差距逐渐减小,衰退型城市能源转型水平最低；小型城市的转型水平明显低于中型城市和大型城市,且中型城市组间差异在不断缩小,大型城市组间差异不断增大；③影响城市能源转型水平的首要障碍层是能源供应层,其次是创新管理层；能源综合生产能力和R&D投入强度是大多数城市的主要障碍因子,不同类型城市的障碍因子不同. 研究结果丰富了对不同类型煤炭资源型城市能源转型路径的探索,对如何实现该类城市绿色低碳发展也具有一定参考. |

| As an important energy reserve base in China, accurate identification of the energy transition level and obstacle factors of coal resource cities of this type is conducive to achieving the carbon neutrality target proposed by China, as well as to the sustainable use of resources. The entropy-composite index method was used to evaluate the energy transition level and diagnose the obstacle factors of 47 coal resource-type cities from 2010 to 2020. The results showed that： ① The energy transition level of Chinese coal resource cities was steadily increasing and the overall transition level tended to be multi-polar, with the gap between cities increasing. Significant differences were observed in the development level of each criterion level and the spatial situation showed a shift from a “decentralized” layout with low level cities to a “clustered” layout with higher level cities as the core. ② From the perspective of different city types, the transformation level of growing cities was higher than that of other types of cities, the gap between the transformation levels of cities was gradually decreasing, and the energy transformation level of declining cities was the lowest. The transformation level of small cities was significantly lower than that of medium-sized and large cities and the differences between the groups of medium-sized cities were decreasing； while the differences between the groups of large cities were decreasing and the differences between the groups of large cities were decreasing. Small cities were significantly lower than medium-sized cities and large cities, the difference between groups of medium-sized cities was decreasing, and the difference between groups of large cities was increasing. ③ The primary barrier layer affecting the level of urban energy transition was the energy supply layer, followed by the innovation management layer. The comprehensive energy production capacity and the intensity of R&D inputs were the major barriers to most of the cities and the barriers to different types of cities were different. These findings enrich the exploration of the priorities and objectives of energy transition in different types of coal resource-based cities and also provide some practical insights into how to achieve low-carbon development in this type of cities. |
