摘要
基于港口城市功能的评价指标体系,采用主成分分析法,提取反映港口城市功能特征的4个主成分因子;运用分层聚类法对我国21个港口城市的主成分得分进行聚类分析;结合港口功能、城市功能、港口与城市关系等指标对我国港口城市功能模式进行总结,并分析不同功能模式港口城市的发展特征和存在问题;基于港口城市功能模式差异性分析,提出我国港口城市发展的几点建议。
Based on the evaluation index system of port-cities, principal component analysis is used to extract the four principal factors reflecting functional characteristics of port-cities; Then hierarchical clustering method is used to classify 21 port-cities into eight categories according to their principal component scores; Functional models of port-cities are further summarized with indexes such as port function, city function, and the relationship between ports and cities, which features and problems are analyzed; Finally, based on the above differences of functional models, some suggestions are proposed on the development of port-cities in China.
