Homogenization Analysis of Airports in China Yangtze River Delta Region
用改进的相似系数衡量长三角机场同质化程度，发现区域枢纽机场同质化最严重，邻近机场因经济结构相似也难免同质化，最后提出整合与差异化策略。
With integrate endow proportion method,this paper build the improved similarity coefficient to measure the homogenization degree of airports in Yangtze River Delta Region.In addition,a network was built with the comprehensive similarity coefficient,the indexes of complex network theory was employed to analyze the construct characteristic of airport homogenization network.Key results show that the airport homogenization of Yangtze River Delta Region is outstanding;the homogenization degree of regional hub airports are the most serious because of their strong radiant intensity and concentrated location;due to the similar urban economic structure,the homogenization of other neighboring airports are inevitable.Finally,the policy recommendations like Integration and differentiation strategy were proposed.
