Nodes Importance Research on the Airway Network of the Silk Road Economic Belt

We construct the aviation network of SREB(domestic part of the Silk Road Economic Belt), which based on Complex Network and Graph Theory. We analyzed the evaluation algorithms for nodes importance, proposed a method for nodes importance of SREB aviation network, which combines the business volume of passenger and freight traffic and the complex network characteristics of ANSREB, and determined the TOP20 vital nodes of the network on two different conditions respectively(without and within international airways). Then we analyzed the reasons that influence the ranking of those nodes.
