Spatial-temporal Evolution of Multi-airports’ Homogenization in China Yangtze River Delta

摘要

The continuous increase of civil aviation demand acts as a spur not only for the government to enlarge inves tment on infrastructure construction, but also for the airport and airlines to improve service to compete for the market share. As a result, the development of airports in the region has experienced a trend of homogenization. This paper aimed to analyze th e homogenization degree of airports in Yangtze River Delta. With the data of airports’ scale, the similarity coefficient and integrated endow proportion method are employed to calculate the homogenization degree, and then the trends and characteristics of airports are analyzed systematically. Further, the homogenization of each airport is taken as the variable to implement the cluster analysis, and the development classes of airports are gained.
