Ocean transportation of bulk cargo is different from container cargo, in that loading/unloading ports are mostly selected by cargo owners rather than the shipping companies. But most studies of port choice in the literature focused on liner shipping, very little effort has been devoted to the issue on port choice behavior for bulk cargoes. The purpose of this study is thus to explore the characteristics of port choice behavior of bulk cargo owners for three selected bulk cargo types, namely chemical product, oil and coal. A questionnaire survey based on the stated preference method is conducted, and disaggregate choice models for each of the three bulk cargo owners are developed on the basis of the surveyed data. Major factors influencing choice behavior and their degree of influence are then discussed based on the elasticity analysis. The result of the study reveals that port cost, inland transportation cost, inland transportation time, port handling efficiency, and cargo damage rate are the major influencing factors, whereas socio-economic attributes of the cargo owners are not significant in general. Strategies such as reducing port cost, increasing handling efficiency, encouraging cargo owners to invest in port areas etc. can be helpful for a port to expand its market share.
