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.
