摘要
基于中国国内65个民航机场、333条航线构建国内航空货运航线网络。通过搜集2016年上述航线国内航空货运运量,采用Pajek软件对该货运航线网络结构进行分析,并对航线载运率进行研究。结果显示:我国货运航线网络具有小世界特征,边缘节点优先与大型枢纽城市节点建立连接;网络发展不均衡,拥有更多航线的城市节点运力也更高,导致大型城市枢纽节点负担过重;我国货运航线网络的载运率整体偏低,特别是连接枢纽城市和东南沿海地区的航线。最后,提出调整航线网络结构与提高航空货载运运率的建议。研究有助于分析我国当前货运航线网络存在的问题,为货运网络结构优化与货邮资源配置提供依据。
This paper builds a domestic air cargo network based on 65 domestic civil airports and 333 domestic airlines. By collecting the domestic air cargo transport volume of the airlines in 2016,the authors analyze the air cargo network by applying the Pajek software,and study the delivery efficiency of the airline. The results showthat the air cargo network of China has the characteristics of small world,the edge nodes have the priority to connect with large hub city nodes,the development of the network is out-off-balance,and the city nodes with more routes also have higher capacity,which leads to the heavy burden of large city nodes,the delivery efficiency of the air cargo network in our country is lowas a whole,in particular the airlines connecting the hub nodes and those of the southeast coastal areas. The authors put forward the proposal to adjust the structure of air cargo network and increase the delivery efficiency of air cargo transportation finally. It is argued that these conclusions can help to analyze the problems existing in current air cargo network,and provide the basis for optimizing the structure of air cargo network and allocation of cargo resources.
