The Research On Cargo Airports Based On Complex Networks And EBM Model

Air transport is the fastest one in all kinds of transportation mode?The network built by cargo airports and airlines which are nodes and edges respectively in the network is air cargo transpotation network,and the network is the space carrier of air transport.Because there are differences in efficiency the development condition of cities and airport infrastructures,airports play different roles in networks.Now,many scholars analysis the efficiency of airports by letting airport infrastructures as inputs,passenger or freight traffic volume as outputs,ignoring the differences in cities'development condition and airport importance.So in this paper,with the two factors considered,a research is done on Chinese air cargo transpotation network.Through collecting datas from 195 airports across the country,the network is built.62 main airports are extracted to build weighted network.Through using the entropy and TOPSIS comprehensive evaluation model the importance of airports are gotten.By EBM model,we use indexes selecting from airport and city aspects as inputs,and the airport importance value as outputs to analysis airports' operation and weakness and get each node input redundancy and output deficiency at the airport by using the super efficiency EBM model,in addition efficient nodes are further analyzed.Through analyzing the input redundancy and output deficiency by super efficiency model,it is found that:Either in effective or ineffective aspect,the airports in south perform better than those in north,the airports in west perform better than those in east;Compared with trunk airports,more regional airports are in an inefficient status which is particularly serious in East and North China region;In the top twenty efficient airports,the trunk and branch airports perform better to the hub airports.
