ABSTRACT Keelung Port has been acted as an important role in Taiwan’s economic development in past decades. However, Keelung Port faces keen competition among neighboring ports and challenges arising from rapid economic growth of mainland China, including Taipei and Kaohsiung port, as well as mainland China’s port, such as Xiamen and Fuchow Ports. Especially, Taipei port’s container terminals start operation since March of 2009. It might cause decrease of container throughput and revenues of Keelung Port. Keelung Port needs to consider its challenges and the future strategies which can be adopted for overcome the above difficulties. In consideration that the ban of direct shipping links across Taiwan Strait has eventually lifted, it is necessary, for Keelung Port, to take this chance for future development. Keelung Port needs to figure out some strategies in coping with the challenges in the future. Based on the viewpoints of terminal operators, this study explores important issues relating to how to adopt port competition strategies in order to meet customerized demand in shipping markets. It also examines the formation of shipping lines connected with Keelung Port, and provides suggestions as to how to adopt marketing measures, including how to focus on short-sea shipping lines, and to be supported by some intercontinental shipping lines. This study suggests to enhance infrastructure of Keelng Port for inducing more intercontinental shipping lines calling at Keelung Port. It also also suggests certain measures to upgrade operational efficency in container whaves in order to meet the requirements of short-sea shipping lines, of which the vessels is required to stay in port shorter than other vessels, and reduce their operational costs, and save the costs in inland haulage. Keelung Port is also suggested to adopt flexible tariff rates in order to improve its competitiveness.
