2017—2022年国内枢纽机场生产效率比较分析

布局完善的航空运输网络是民航业发展的关键。枢纽机场作为航空运输网络的重要节点,在机场网络中扮演着重要角色。运用超效率SBM(基于松弛值测算)模型和Malmquist模型,选取2017—2022年国内39个枢纽机场数据为样本进行静态与动态分析。结果表明,研究期间我国枢纽机场生产效率处于“无效”阶段,受新冠肺炎疫情影响国际航空枢纽机场生产效率下降幅度大于区域枢纽机场,所属华东机场群的枢纽机场受新冠肺炎疫情影响最大,西北机场群的枢纽机场虽然新冠肺炎疫情前效率最低但下降幅度最小。

Comparative Analysis of Productivity Efficiency at Domestic Hub Airports from 2017 to 2022

A well laid out air transport network is the key to the development of the civil aviation industry.Hub airports, as important nodes in the air transport network, play an important role in the airport network. Based on the super-efficient slacks-based measure (SBM)model and Malmquist model, a sample of 39 hub airports in China from 2017 to 2022 is selected for static and dynamic analysis. The results show that the productivity of China''s hub airports is in the "ineffective" stage during the study period, and that the productivity of international airports has decreased more than that of regional hub airports due to the COVID-19, with hub airports belonging to the East China Airport Cluster being the most affected by the COVID-19 and hub airports in the Northwest China Airport Cluster having the lowest efficiency before the COVID-19 but the least decrease.
