Abstract:

One important role of high speed transportation network is to promote the spatial agglomeration of traffic flow, which leads to changes of spatial interaction. Air transportation in China grew rapidly in the past two decades and is playing more and more important roles in state transportation system. Due to the improvement of aviation service and the expansion of air transport network, the inter city linkages among domestic cities are getting enhanced, and hierarchical network is taking shape. In this paper, air passenger network in China is analyzed. The results of dominant flow analysis indicate that the air passenger flow between cities increased quickly in the past two decades, and “Hub and Spoke” network has been formed basically. Beijing, Guangzhou and Shanghai are the most important hubs in China's domestic air passenger network, and Urumqi and Kunming are important local hubs. According to the statistical analysis, the passenger flow between cities is closely related to the distance, urban scale, and urban function. In China, about 90% of domestic air passenger traffic takes place between cities where the inter city transport distance is less than 2 400 km. In order to raise the efficiency of air transportation system, it is very important to organize the passenger network between hub and local airports.
