Abstract: With the continuous improvement of the economic and social value of air transport,as the carrier of air transport,the research and analysis of air transport network structure is of great significance.Based on the flight data of major airlines in China,this paper used complex network theory to analyze the network characteristics of China’s aviation network,and proved that China’s aviation network is a small-world network with scale-free characteristics.By analyzing the basic statistical characteristics of China Aviation Complex Network in 2015,we found that the average path length decreases,the average degree of nodes increases,and the clustering coefficient tends to be stable.After that,the paper analyzed the interaction of node index,edge index and weighted index of China Aviation Complex Network,and studied the influence of different index changes on network structure and its practical significance.In addition,the paper found that the degree-degree correlation,degree-weight correlation and betweenness-betweenness correlation,which reflect the connection preference and structural characteristics of China Airline Network,are negative.Finally,the application analysis and prospect of the research results were carried out.
