国航中转航班时空间分布特性及影响研究

Study on Characteristics and Impacts of Temp-spatial Distribution for Air China’s Indirect Flights

以中国国际航空公司(简称国航)在北京首都机场(PEK)的国内转国际中转航班为研究对象,从时空间维度研究其中转时间分布特性,提出可变最大中转时间、喂给能力和喂给利用指数3个表征指标,并构建回归模型分析其影响。结果表明国内经PEK中转西欧、东北亚、北美和东南亚的最大中转时间参考阈值均不同,同时,国航在PEK对喂给能力强的始发机场的直达航班利用程度不高。模型估计结果验证了表征中转时间时空间分布特性的指标对国航首都机场的中转航班量产生显著影响。结果将为全服务航空公司在其枢纽机场构建航班波系统结构提供理论参考。

This paper investigates the temporal and spatial distribution characteristics of connecting time for Air China’s connections at its hub airport–Beijing International Airport(PEK)for domestic to international connecting flights.Three indicators,i.e.,maximum connecting time,feeding ability and feeding utilization index,were proposed to characterize the indirect connections.A multivariate regression model was further established to study their impacts.The result shows that the threshold of maximum connecting time varies among different regions.Meanwhile Air China does not fully explore the nonstop flights of origin airports when creating indirect connections.The model shows that factors representing the characteristicsof connecting time have significant impacts on the number of indirect flights.The results will provide a theoretical basis for Chinese full-service carriers to build wave-system structureintheir hub airports.
