This paper selects energy consumption data of 11 provinces in YRB and 19 provinces and cities in non-YRB from 2014 to 2016 and constructs a shared border Metafrontier non-radial directional short model, adding CO and AQI indicators as undesirable factors, in order to evaluate the total efficiency and the input and output efficiencies of these two regions. The results are as follows. (1) From the changes in the score and ranking of the two regions' total environmental efficiency, only two provinces in YRB show a slight decrease, while most of them show a stable or rising trend; seven provinces in non-YRB have a low rising rate. This means during the study period that YRB made more progress at energy conservation, emission reduction, and pollution control than other provinces and cities in non-YRB. (2) The efficiency scores of energy consumption, GDP, CO, and AQI emissions are different in each province. Overall, the situation of YRB is better than that of non-YRB. Not only is the efficiency score of each index higher, but the efficiency difference between provinces and cities within the region is small, which is conducive to the linkage effect of the region and the realization of green coordinated development.
本文选取了 2014-2016 年中国 11 个沿黄省份和 19 个非沿黄省份和城市的能源消费数据，构建了共享边界 Metafrontier 非径向定向短距离模型，加入 CO 和 AQI 指标作为非期望产出，以评价两个区域的全要素效率以及投入和产出效率。结果表明：（1）从两个区域全要素环境效率的得分和排名变化来看，沿黄省份仅有两个省份呈现出微弱的下降趋势，其他大部分省份则呈现出稳定或上升的趋势；而非沿黄省份七个省份的上升率较低。这说明在研究期间，沿黄省份在节能减排和污染控制方面比非沿黄省份的其他省份和城市取得了更大的进展。（2）能源消费、GDP、CO 和 AQI 排放的效率得分在各省之间存在差异。总体而言，沿黄省份的情况要好于非沿黄省份。不仅每个指数的效率得分更高，而且区域内各城市之间的效率差异较小，这有利于区域的联动效应和绿色协调发展的实现。
