Network Spatial Structure and Change of Spring Airlines

摘要: 基于2015年和2019年全国航班时刻表的国内航班数据及飞常准大数据平台，分析春秋航空的通航城市、航线的网络及其空间结构。结果表明，春秋航空通航机场主要聚集于东部地带、华东机场群，五年来，通航城市“东多西少、南多北少”的整体格局变化不大，航线航班的空间布局以上海为中心的集聚程度降低；通航机场数量、航线数量呈现增长态势，并以上海为中心向全国辐射，在石家庄、沈阳、扬州等地向周围散射的格局；航距明显变长，但平均通航航距有所减少。

Abstract: Based on the domestic flights from national flight schedules and VariFlight’s big data platform of 2015 and 2019, this paper analyzes the navigable city, route network and spatial structure of Spring Airlines. It concludes that the navigable airports of Spring Airlines are mainly concentrated in the eastern region and the eastern China airfield complex. In the past five years, there is little changes in the overall pattern that is much more in the east and less in the west, much more in the south and less in the north. The spatial distribution of air routes and flights with Shanghai as the center is less concentrated. The number of navigable airports and air routes shows an increasing trend, and radiates to the whole country with Shanghai as the center, scattering around Shijiazhuang, Shenyang, Yangzhou and other places; the cruising distance is obviously longer, but the average cruising distance is reduced.
