区域机场同质化发展特征分析——以长三角地区机场群为例

Homogenization Analysis of Airports in China Yangtze River Delta Region

通过构建测量区域机场同质化发展的改进相似系数,运用综合赋权评价法,对长三角地区机场发展的同质化水平进行测算,并以综合相似系数构建机场同质化网络,采用复杂网络结构方法对机场同质化网络进行分析。结果表明:长三角经济核心圈机场存在明显的同质化水平;枢纽型机场由于机场辐射能力强且分布密集而同质化水平最为明显;核心边缘的地区型机场由于城市经济规模小且距离较近,机场为了进一步发展而产生趋同化;其他地区型机场则由于长三角地区内城市经济结构的相似,邻近机场间的服务呈现趋同化。最后,针对长三角地区机场同质化发展特征提出区域机场一体化和差异化发展的政策建议。

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.
