This chapter reviews and analyses the contemporary development of liner shipping, port development and competition. It begins with a comprehensive review on the latest developmental trends of liner shipping and business strategies, as well as their impacts on port development and competition. Then, it discusses the responses of ports, past, present and (likely) future, in addressing these new demands and challenges. A very important point from this analysis indicates that, in the past decade, port development and competition have gradually evolved from being individual, technical efficiency-oriented to become more regional, economic efficiency-oriented. At the same time, ports have also moved out of their rather passive positions and undertaken positive steps to avert the traditionally strong bargaining power of shipping lines. This illustrates that port development and competition is a continuous morphological process which can change dramatically within a rather short period of time. This chapter provides a new perspective on port development and competition and a decent platform for further research.
