Examining the convergence characteristics of energy eco-efficiency in the Yellow River Basin (YRB) is of great significance for the sustainable development of China. It fulfills the international commitment to carbon peak and carbon neutrality. Based on the Super-EBM model and ML index, this paper measures the energy eco-efficiency of 60 cities in the YRB during 2006-2018, and then spatial and temporal patterns are both analyzed before the final investigation of the convergence in the YRB. The results show the following: (1) From 2006 to 2018, the energy eco-efficiency of the YRB showed a significant upward trend, but there was still a 25.61% improvement compared with the production frontier. (2) The spatial differentiation of the energy eco-efficiency in the YRB was significant, and the inter-regional differences were the main reason for this. (3) There was no -convergence in energy eco-efficiency in the YRB during 2006-2018, but absolute and conditional -convergence did occur. (4) Although the significant factors in the convergences were different, the levels of energy eco-efficiency in the different reaches all developed towards stable levels, and the catch-up effects in the less-developed regions were significant.
考察黄河流域（YRB）能源生态效率的收敛特征，对于中国的可持续发展具有重要意义。这符合中国在碳达峰和碳中和方面的国际承诺。基于超效率模型和 ML 指数，本文测算了 2006-2018 年黄河流域 60 个城市的能源生态效率，然后分析了时空格局，最后调查了黄河流域的收敛情况。结果表明：（1）2006-2018 年，黄河流域能源生态效率呈显著上升趋势，但与生产前沿相比仍有 25.61%的提升空间。（2）黄河流域能源生态效率的空间差异显著，区域间差异是主要原因。（3）2006-2018 年黄河流域能源生态效率不存在-收敛，但存在绝对和条件-收敛。（4）尽管收敛的显著因素不同，但不同河段的能源生态效率水平都朝着稳定水平发展，欠发达地区的追赶效应显著。
