- 摘要:
- 针对区域港口群竞合关系的复杂性、多重性问题，引入了可拓学中的基元理论，提出了一种新的复杂网络模型构建方法，这种方法使得多重关系的同时分析成为可能。在构建了基于基元的区域港口群竞合网络模型之后，运用Ward聚类、网络密度分析、网络中心性分析及结构洞分析等方法，研究了区域港口群竞合网络的结构特征及社会属性特征，帮助港口管理人员进行相关决策。最后，选取珠三角港口群进行实例分析以验证网络分析方法的有效性，主要结论包括：港口中心性与其港口层次保持一致；竞争网络中，若低层次港口具有过高中心性，则该港口有定位不明或过度竞争的可能；高中心度的枢纽港对其他港口进行喂给，会对被喂给港口形成较强的限制。
- Abstract:
- This paper focuses on the complexity and multiplicity problem of the co-competition relationship in the regional port group. Based on the basic-element theory in Extenics, a new method was proposed to construct complex network models. This new method makes it possible to analyze multiple relationships concurrently.After the regional port group co-competition network model was built, the structural characteristics and social attributes of the network were researched using the methods of Ward clustering, network density, network centrality analysis, and structure hole analysis, etc.The results are useful for the port administrators for their management decisions. Furthermore, the port group of Pearl River Delta was selected as an example to prove the validity of the above models. The major conclusions include three aspects. One, the centrality of one port is in accordance with its level in the group. Two, if some feed ports have high centrality in a competition network, in all probability, they have indistinct development orientation or excessive competition. Three, if one port is fed by another port with high centrality, then it will be strongly restricted by that port.
