我国民航货运网络的统计特性分析

Statistical Characteristics of Air Cargo-transport Network of China

以我国民航机场所在的城市作为节点,城市间民航航班所提供的货运运力作为边的权重,对该民航货运网络的结构及统计性质开展分析,这有助于明确民航货运网络上的运力配置情况、为优化民航货运网络资源配置提供决策参考。我国民航货运网络兼具无标度与小世界的特性;节点度较大的城市节点之间所配置的货运运力规模也较大;大型城市节点在整个民航货运网络中的地位显著,区域性枢纽城市节点在整个网络上也具备不可或缺的重要性。此外,我国民航货运网络存在区域性枢纽网络范围内的点点直达运力偏弱等问题。

Taking cities with domestic civil airports as nodes and air cargo-transport capacity between two cities the edge weight, this paper analyzes the topology and statistical characteristics of air cargotransport network of China （ACNC）. The study intends to reveal the distribution of air cargo-transport capacity on the ACNC, and hence optimize the use of aircraft capacity on the ACNC. The ACNC is both a scale-free network and a small-world network. The air cargo-transport capacity between two large city nodes is usually large. Large city nodes on the ACNC play a significant role, and the regional hub cities are also important. The point-to-point cargo-transport capacity on regional suhnets of the ACNC is relatively weak.
