Abstract: On the basis of defining the concept of airline operational efficiency， the research results of airline operational efficiency are summarized from three aspects， including research content， research methods and research indicators. The research found that: First， a large number of scholars have done a lot of research on transport airline operational efficiency， but there are few studies on the general airline operational efficiency and route operational efficiency. Secondly， there are various methods to measure the airline operational efficiency， but few qualitative studies. And the research ideas are similar. There are few research contents that combine operational efficiency with other aspects. Thirdly， from the calculation and evaluation of the overall airline operational efficiency， to the attention to various detailed input factors and the expansion of route operational efficiency， the research focus has been constantly changing.

摘要： 在界定航空公司运营效率概念的基础上，从内容、方法及指标三个方面梳理和总结归纳航空公司运营效率的研究成果。研究发现：运输航空公司运营效率已有大量研究，但通用航空公司和航线运营效率研究较少；航空公司运营效率测算方法多样，但研究思路趋同，定性研究及与其他方面结合研究的成果很少；从对航空公司整体运营效率的测算，到对投入因素的关注，再向航线运营效率拓展，研究重点不断发生转换。
