Research on Structural Characteristics of Homogeneity Development of Multi-Airport in Yangtze River Delta Region

摘要

The homogeneous development of airports in the multi-airport region hinders labor division and cooperation among airports. This study used similarity coefficient to evaluate degree of homogeneity. Three indexes were chosen to calculate similarity coefficient from three different aspects. The similarity coefficient of each couple of airports under the three indexes is calculated, respectively. A comprehensive weighting evaluation method is applied to evaluate the comprehensive similarity coefficient of each couple of airports based on the value of the three kinds of similarity coefficient, and the homogeneity network of multi-airport in the study region is constructed according to the evaluation results. Based on the complex network theory, the structural characteristics of homogeneity network are analyzed, which correspond to the structural characteristics of homogeneity development of airports in multi-airport region. Finally, based on the structural characteristics and balance on each airport's gains and losses, this study made three targeted planning adjustments.
