Considering the different roles of PAs and private players in ports, the concept 'Port focused Supply Chain' (PSC), including container terminals, inland transport companies and depots, is adopted for the current study. After a literature review and exploratory factor analysis, twelve specific variables, i.e. PAs' 'concessions', 'using IT', 'marketing', 'support for hinterland and FTZ', PSCs' 'vertical integration', 'relationship orientation', 'skills', 'physical 'resources', and PSCs' 'reliability', 'flexibility', 'costs', and 'service effectiveness' were chosen for the PLS (Partial Least Squares) analysis. The questionnaire survey was distributed to 1,208 surveyees, i.e. experts in headquarters, branches, agents of the shipping liner companies and freight forwarders using Korean and Chinese ports. From 12th March to 3rd May 2007,124 responses were collected. It is shown that PAs' 'using IT' strategy can positively affect PSCs' SCP through 'PSCs' relationship orientation', and 'skills'. Among the variables of PSCs' SCM, 'relationship orientation' makes a stronger impact on PSCs' resources than 'vertical integration'. 'Skills' is more powerful in determining PSCs' SCP than 'physical resources'. While 'physical resources' has a significant relationship with two variables (cost and service effectiveness), 'Skills' has positive influences on all the four variables of PSCs' SCP. Singapore's SCP exceeded the SCP scores of other rivals, i.e. Hong Kong, Busan, Shanghai, and Gwangyang port. Except Shanghai port, the container cargo volumes of the other four ports were consistent with their SCP. In conclusion, the implication for PAs can be that PSCs' performance can be improved by utilizing coherent SCM strategies. Further research investigating the impacts of PAs' SCM strategies is recommended. ACKNOWLEDGEMENTS I have always had a dream of the moment that I finished the acknowledgement during my whole Ph.D. period. And I am now approaching that moment. I should express my thanks to everyone who helped and supported me. They all made my Ph.D. time as a very precious experience that I cannot forget for the rest of my life. First of all, I would like to thank my supervisors, Dr. Anthony Beresford, Dr. Stephen Pettit and Professor Peter Marlow. Especially, I appreciate Dr. Beresford's invaluable advice which was always warm, and stimulating me. Also, I would like to thank South Korean government. Without their support, I could not imagine a chance to study for a Ph.D. I hope that they will be proud of their decision. I would like to thank Bo-Sun Kim, my wife, who has been assisted my decision to pursue a Ph.D. and gave me a great deal of encouragement whenever I was in trouble. My son, 'Woojae' and daughter, 'Hyunjae' have always been an inspiration to me. My thanks should go to Ms. Daisy Wang for her neat and clear translation for the Chinese version of the questionnaire, and Mr. Sang- jin Shin for his great effort in building the website for the questionnaire. Finally, I must say that I owe a lot to my parents, Duk-wha Hong and Young-ja Cho. Without their love and trust, I can not imagine that I could accomplish any of my achievement such as completing this Ph.D. thesis.
