This study has collected the historical data from vessel traffic database of major container terminals in the port of Kaohsiung, including the three geographical regions the vessel served (i.e. main trunk services, intra-regional services, and the across-Taiwan Strait/Hong Kong services), the terminals of calls in Kaohsiung and the size of the container vessels visit the terminals, to analyze the operational efficiency and competitive situation among these dedicated container terminals. In addition, current container terminals-sharing situation is reviewed and the impact of the prevalence of shipping alliances on current terminals lessees is also analyzed. The results reveal that some ocean carriers-operated dedicated terminals operators have not performed efficiently as it is evidenced by the low amount of their own ships called at their own container terminals in Kaohsiung. It should be cautiously monitor whether or not these terminal operators will reduce their transshipments traffics in Taiwan and exclude the Kaohsiung port from their voyage routings. Further, only ocean container carriers engage in main trunk services have used the dedicated terminals owned by their alliances members, but the terminal sharing between alliance members is not popular when ocean container carriers are engaged in intra-regional services. The prevalence of shipping alliance would possibly reduce the ocean container carriers, intention to rent the container terminals at the Port of Kaohsiung. However, it is suggested that the Taiwan International Ports Corporation, Ltd. should provide incentives for the non-allianced ocean container carriers to attract them to lease and operate their dedicated container terminal in Kaohsiung.
