Over recent decades the global economy has tilted from a trans-Atlantic Euro-American economy towards an Asia-Pacific one, a shift encapsulated by the term Pacific Century. Nine Group of Twenty (G20) nations – Australia, Canada China, Indonesia, Japan, Mexico, Russia, South Korea, and the USA – are contiguous with the Pacific Rim. Yet despite common use of the adjectives Pacific, trans-Pacific, and Asia-Pacific, the boundaries and structure of this notional economy are still vague. This chapter maps the articulation of a Pacific economy since 1945 through geologistics as a two-stage process, first reformation and densification of pre-war networks until the end of the 1960s, then transformation through the new technologies of container shipping, jet aircraft, and the Internet. It becomes apparent that this transformation had had much greater impact upon adjacent continental economies than upon the vast coastal and almost hollow archipelagic region that may be denoted as Pacifica.
