Port cities will be classified into three categories, load center, maritime city and world city, depending on their service level. This article focuses on maritime cities, where management functions in maritime sector agglomerate, and explores the factors behind their agglomeration in 2012 by statistical correlation analysis to international container throughputs, the number of advanced maritime producer services (AMPS) firms and city rank based on the number of advanced producer services (APS) firms. The results reveal that the location of management Junctions in maritime sector in Asia is strongly co-related to the agglomeration of AMPS firms, rather than to the port container throughputs. This finding suggests that a port city government should consider port policies attracting AMPS firms in order to become a "maritime city".

Asia now stands as the largest aviation market on the globe, which is underpinned by an intensive network of connections within the region. Fifteen out of the top world’s twenty busiest international routes by frequency operate in this region in 2018, showing that the intra-regional flight numbers are much larger than the inter-continental ones. The current paper develops the insight on this perspective by running the model separately for intra-regional and inter-continental air traffic movements. The results sort out the strengths of cities with a higher level set being more active in the global links, confirming that there is a hierarchy of regionally-linked cities and also a hierarchy of globally-linked cities, which underlines the city role in an Asian context.
