经济视角下的航空货运网络结构分析

随着经济的快速发展和信息流通的加快，航空货运在经济发展中的作用日益凸显。航空货运的发展依赖于货运网络的完善，体现出构建中国航空货运网络的重要性。以中国城市经济发展形态为切入点，以中国各城市间航段货邮运输量为样本数据，绘制出2004--2009年中国航空货运网络结构图，建立航空货运网络核心一边缘结构模型．并对其平均路径长度、网络集聚系数、度分布、边权分布和点权分布进行分析。结果表明：中国航空货运网络具有聚集效应，对经济发展具有一定的推动作用，并在此基础上呈现中国航空货运网络的进一步完善发展方向．

Analysis on structure of air cargo network of China based on economy

With the development of economy and speeding up of the information flow,air cargo becomes increasingly important in the economic development. The development of air cargo depends on the completion of its network construction,which reflects the importance of building China＇s air cargo network. Taking domestic urban economic development as a starting point,using the cargo and mail transport volume of the city legs as sample data,the author establishes a domestic air eargo network structure chart and a mode of air cargo network structure network core-periphery model 2004--2009,analyzing irrespective path length,network clustering coefficient,degree distribution,edge power distribution and point power distribution. The results show that domestic air cargo network has gathered-effects and has been playing a role in promoting development,which directs the further improvement of Chinese air cargo network development.
