我国国内航空货运航线网络结构的实证分析

为了全面分析我国航空货运航线网络结构的现状,准确把握航空货运航线网络结构中存在的问题,本文运用统计分析和网络拓扑分析的方法,对我国国内航空货运样本航段的运量进行分析,计算结果显示:我国航空货运枢纽与客运枢纽具有高度叠加性,货运枢纽较客运枢纽更为显著;我国航空货运航线网络中的机场层次更加丰富;2007年航线网络的便利性较2002年有所提高;目前我国国内航空货运航线网络仍以城市对式航线网络结构为主,但也存在不均衡发展、多结构共存的现象。

In order to analyze the present situation of airline network structure of domestic air cargo and grasp the existing problems,the author studies the freight volume of the sample route segment by applying the methods of statistical analysis and topological analysis.The results has showed that the freight hubs are highly overlapped with the passenger transport hubs,and the freight hubs are more obvious;the airport types of freight hubs are diverse;the airline network in 2007 is more convenient than the airline network in 2002;at present the airline network of domestic air cargo is mainly the point-to-point structure among the cities.There are the phenomenon of unbalanced development and multiple structures co-existing and is characteristic of unbalance development and coexistence of different structure.
