The Chinese City Function Network Based on Aviation Passenger Flow
利用航空客流数据，通过主导流、枢纽度和引力模型将中国城市分为主节点和次节点，分析城市功能网络，发现上海、北京为全球节点，GDP和人口对客货运影响显著。
Aviation flows as an important transportation mode has already been widely used in European and American city network system research. Based on city function network research review, using dominant flow, hubness and gravitation mode to classify Chinese cities into main nodes and secondary nodes to analyze Chinese city network system is a new research view. The research comes to these conclusions: ① Shanghai and Beijing as global urban nodes have important roles; ②Guangzhou and Shenzhen as important cities in PRD have relatively high hubness; ③Western urban function shows divisions as no dominant city exist, Chengdu, Chongqin, Xi'an and Wulumuqi form regional hub; ④ Influenced by other transportation means, Wuhan shows relatively low aviation hubness; ⑤ Nanjing, Hangzhou and Fuzhou are influenced by regional dominant cities; GDP and population sizes have significant influences on guest and cargo aviation flows while aviation distance shows relatively low influence.
