Evaluation of Port Position for Intra-Asia Maritime Network

抄録

This paper aims to evaluate port position in the Intra-Asian maritime container network based on centrality measures. From the results, main hub ports such as Singapore, Hong Kong, Busan, and Shanghai are identified as occupying pivotal positions in Intra-Asia in terms of centrality measures. Busan port is an important linkage for the pairs of other ports, especially for Japanese local ports. However, the closeness of Busan port is somehow lower, since its geographical advantage is relatively small in the Intra-Asia maritime network. Chinese and Taiwanese ports have more closeness due to their geographical centrality in the Intra-Asian network. Moreover, Surabaya port has high betweenness in Indonesia, which acts as an important bridge for Indonesian local ports in the Intra-Asia network.
