With rapid urbanization and industrialization in developing countries, cities have become the major sources of air pollution. Studying urban atmospheric environmental efficiency has an important reference value for the prevention and control of air pollution. This study used data from 267 cities in China between 2001 and 2016 to assess the urban atmospheric environmental efficiency using the super-efficiency slacks-based measure model, to test the spatial characteristics of urban atmospheric environmental efficiency using the spatial autocorrelation method, and to identify factors influencing it using the Geodetector. The results are as follows: (1) The atmospheric environmental efficiency of most cities in China is increasing. The average efficiency in the entire country exhibits an upward "wavy" trend. The average urban atmospheric environmental efficiency in Eastern China is the highest, and that in Western China is the lowest. (2) The urban atmospheric environmental efficiency exhibits the characteristic of global spatial autocorrelation, and high-high and low-low are the main types of efficiency in local spatial autocorrelation. (3) Population density, industrialization, and science and technology are the main factors influencing urban atmospheric environmental efficiency.
随着发展中国家快速的城市化和工业化进程，城市已成为空气污染的主要来源。研究城市大气环境效率对空气污染的防治具有重要的参考价值。本研究利用2001年至2016年间中国267个城市的数据，采用超效率松弛测度模型评估城市大气环境效率，运用空间自相关方法检验城市大气环境效率的空间特征，并使用地理探测器识别影响其的因素。结果如下：（1）中国大多数城市的大气环境效率在提高。全国平均效率呈向上的“波浪”趋势。中国东部地区城市大气环境平均效率最高，西部地区最低。（2）城市大气环境效率呈现全球空间自相关特征，高高和低低是局部空间自相关中的主要效率类型。（3）人口密度、工业化和科技是影响城市大气环境效率的主要因素。
