针对国际环境变化下港口间盲目竞争的现状,提出港口间特别是港口群内港口间应该选择协同发展保持竞争力。为了更好地帮助港口进行功能定位和资源优化配置,在阐述港口耦合度与协同发展水平关系的基础上,构建了港口群系统耦合测度模型,依据耦合度大小描述了港口群内港口的不同耦合模式;并利用基于信息熵的粗糙集约简方法定量对系统序参量指标属性权重和属性重要性进行求解;最后通过对山东半岛港口群系统进行实证分析,测度了港口群内港口间耦合状态和协同发展水平,验证了耦合测度模型的有效性。
針對國際環境變化下港口間盲目競爭的現狀,提齣港口間特彆是港口群內港口間應該選擇協同髮展保持競爭力。為瞭更好地幫助港口進行功能定位和資源優化配置,在闡述港口耦閤度與協同髮展水平關繫的基礎上,構建瞭港口群繫統耦閤測度模型,依據耦閤度大小描述瞭港口群內港口的不同耦閤模式;併利用基于信息熵的粗糙集約簡方法定量對繫統序參量指標屬性權重和屬性重要性進行求解;最後通過對山東半島港口群繫統進行實證分析,測度瞭港口群內港口間耦閤狀態和協同髮展水平,驗證瞭耦閤測度模型的有效性。

The change of international environment leads to blind competition between ports.In order to keep a suatainable development and competitiveness,ports shoud develop in a synergetic way,which could better help ports with functional positioning and optimal distribution of resources.With introduction of the relationship between coupling level and synergetic development,this article constructs a coupling measurement model of the port cluster system.Then it describes the various patterns with different coupling level.With the method of rough sets reduction based on information entropy,index attribute weight and attribute significance are calculated.Finally the paper makes an empirical analysis of the Shandong Peninsula port cluster system to measure the coupling level and verify the validity of the model.
