Abstract: Index evaluation is used to empirically analyze the route network configuration of different types of airlines in China based on the degree of network spatial-temporal concentration. Rosenblas Index, which is used to evaluate concentration in industrial economics, is firstly introduced into air transport network combining with improved Gini Index, Relative Entropy Index and HHI Index to evaluate spatial concentration in airline network.Meanwhile, flight frequency cohesion degree is employed to evaluate network time concentration. By synthetically analyzing the spatial and temporal concentration of different types of airlines, the difference between network configurations are obtained. Analyses show that low-cost airlines have higher spatial concentration and lower time concentration, who mainly develop PP to HS route network; Besides Air China, which has higher spatial concentration and lower time concentration and is typically PP route network, other big full-server airlines are gradually transiting from PP to HS route network; With the expansion of scale, the spatial concentration of small and medium-sized full-service airlines gradually increases, while the time concentration basically remains unchanged, PP route network is mainly developed.

Key words: airlines, time-space concentration, index assessment, network configuration
