Abstract:

As an important traffic infrastructure, the airport is of great significance for local business and residents. The connectivity level of the air network represents the level of air transport services. This paper analyzes the air network of China based on social network analysis, by calculating the density, centrality, cut off point and the total loss of every deleted airport. It makes a conclusion that the connectivity level of domestic air network of China as a whole is relatively lower and the eastwest differences in the connectivity level is obvious. There is also a characteristic network structure exit in some particular regions of the west. Meanwhile, the whole network greatly relies on the Beijing Capital International airport.
