This document discusses the concept of an "aerotropolis", where airports become the center of large-scale commercial and economic development, rather than just transportation hubs. It notes that global air travel and cargo are projected to greatly increase in coming decades, leading airports to develop extensive commercial areas that function as regional economic centers. The document examines examples of major airports that have catalyzed nearby office, hotel, manufacturing and mixed-use developments. It argues that Asia is well-positioned to implement the aerotropolis model due to many new airports and high economic growth rates. Planning principles are outlined for holistically developing airport cities that maximize regional competitiveness.
