港口集群以产业集群理论为基础,它是研究港口竞争力问题的一种新的理论方法,而集群内部竞争对于提高一个港口的整体竞争力非常有利,它们是加强港口集群竞争力的一个重要因素。本文首先将产业集群的概念应用到港口中来界定港口集群和内部竞争,提出了实施路径来鼓励内部竞争,探讨了如何提高港口集群的效益。 Port cluster is based on industrial cluster theory, which is a new theoretical method to study port competitiveness. Intra-cluster internal competition is very beneficial to improve the overall competitiveness of a port, which is an important factor to enhance the competitiveness of port cluster . This paper first applies the concept of industrial cluster to the port to define the port cluster and internal competition, puts forward the implementation path to encourage internal competition and discusses how to improve the efficiency of the port cluster.
