摘要
为探究我国同东盟航空运输联系发展水平,采用修正的引力模型对联系强度进行测算,基于测算结果构建中国与东盟城市航空运输联系空间网络,运用复杂网络方法对网络总体特征和节点中心性进行分析,发现我国与东盟航空联系强度较弱,整体呈上升趋势,联系的不均衡性较为明显;整体网络结构较为松散,呈现出“核心—边缘”的分布特点;度分布表现出多级分化现象,网络由少数核心城市主导,接近中心性总体分布均衡。
In order to explore the development level of air transport links between China and ASEAN,a modified gravity model is used to measure the strength of the links,and a spatial network of air transport links between China and ASEAN cities is constructed based on the measurement results,and the overall characteristics and node centrality indicators are analyzed using the complex network method.The strength of China's air links with ASEAN is weak,the overall trend is upward,and the unevenness of the links is obvious.The overall network structure is loose,showing the distribution characteristics of"core-periphery".The degree distribution shows multi-level differentiation,the network is dominated by a few core cities,and the overall closeness centrality is balanced.
