摘要
根据世界航空客运的海量样本数据,以153个国家(地区)为节点,以国家(地区)间客运航线为边,建立了世界航空客运网络,并对其复杂性进行了分析。分别考察了世界航空客运网络复杂性的指标——路径长度、网络集聚系数和幂律分布系数。特别对客运网络度的分布特征进行详细考察,从无向、有向和点强度等三个方面探讨了该网络的度分布特征,证明它们均服从幂律分布,说明世界航空客运网络的度分布存在着较高的不均匀性,是一个无标度网络。
According to the huge data from International Air Passenger Transport Database, we construct an International Air Transport Network （IATN）, which concludes 153 vertices denoting different countries （regions）, and many edges denoting international routes between countries. We analyze the complexity of this network through several standard indices： Average Distance, Clustering Coefficient, and Power Law Distribution. Specially, we illustrate the distribution property of the network degree, under undirected edges,directed edges, and different node strength. We prove that all the results have Power Law Distribution, which means that the distribution of degree in IATN is inhomogeneous. Thus, IANT is a scale-free network
