【摘要】 采用聚类分析与社会网络分析相结合的方法,构建港口竞合关系分析模型,通过对社会网络分析(SNA)中心势、中心度、中间性的分析,对竞合港口进行合理分层,识别出港口竞合关系关联强度、不同层次的核心港口及中介型港口,并以此作为制定港口竞合关系发展战略的依据.对珠三角港口群的分析验证了该模型的有效性.更多还原

【Abstract】 The method combining cluster analysis with social network analysis(SNA) was used to establish the model of ports co-competition relationships.The centrality and betweenness methodology in SNA were studied,and the center of different levels of ports and the intermediary type port were recognized,which could be the basis for decision-making.The ports group of Pearl River Delta is taken as an example for the verification,and result shows the effectness of the proposed method.更多还原
