基于复杂网络的中国四大机场群多极航线网络结构特征分析

为了科学优化我国机场群航线网络发展布局，以京津冀、长三角、粤港澳大湾区、成渝双城经济圈四大世界级机场群作为研究对象，基于复杂网络分析方法构建了机场群航线客运网络模型，测度航线网络结构的基本特征指标、中心性指标以及机场群成员间相似系数。结果表明：四大机场群航线网络均具有小世界网络和无标度特征；网络中心化程度较高，具有紧密集中趋势，机场间航线分配不均匀，通达性差异大，枢纽机场控制作用突出；长三角机场群成员间航线同质化特征显著，明显高于其他三个机场群。

Analysis on the Characteristics of Airline network in China's Four Major Multiple-airport Systems Based on Complex Network

For scientific optimization in developing multiple-airport systems of the route network layout,in Beijing-Tianjin-Hebei,Yangtze River Delta,Greater?Bay?Area, Chengdu-Chongqing Economic Zone the China''s four major airport group as the research object, based on complex network analysis method to to build the multiple-airport systems of airline passenger transport network model, to measure the basic features of the airline network structure, centrality and isomorphism among the members of the four major multiple-airport systems. The results show that the airline networks of the four multiple-airport systems all have the characteristics of small-world network and scale-free. The network has a high degree of centralization, with a close centralized trend, uneven distribution of airline between airports, great differences in accessibility, and prominent control role of hub airports. The degree of airline homogeneity among the members of The Yangtze River Delta multiple-airport systems is significantly higher than the other three multiple-airport systems.
