Aerotropolis

An aerotropolis is a metropolitan subregion where the layout, infrastructure, and economy are centered on an airport which serves as a multimodal "airport city" commercial core. It is similar in form to a traditional metropolis, which contains a central city commercial core and commuter-linked suburbs. The term was first used by New York commercial artist Nicholas DeSantis, whose drawing of a skyscraper rooftop airport in the city was presented in the November 1939 issue of Popular Science. The term was repurposed by air commerce researcher John D. Kasarda in 2000 based on his prior research on airport-driven economic development.

According to Kasarda, airports have evolved as drivers of business location and urban development in the 21st century in the same way as highways did in the 20th century, railroads in the 19th century, and seaports in the 18th century. The engine of the aerotropolis is the airport and its air routes which offer firms speedy connectivity to their distant suppliers, customers, and enterprise partners worldwide. Some aerotropolis businesses are more dependent on distant suppliers or customers halfway around the world than those located nearby. As economies become increasingly globalized and reliant on air commerce for trade in goods and services, the speed and agility aviation provides to long-distance movement of people and goods generate competitive advantages for firms and places. In the aerotropolis model, time and cost of connectivity replace space and distance as the primary metrics shaping development, with "economies of speed" becoming as salient for competitiveness as economies of scale and economies of scope. In this model, it is not how far, but how fast distant firms and places can connect.
