Since founding in the 17th century, Kaohsiung has grown from a small trading village into the political and economic centre of southern Taiwan, with key industries such as manufacturing, steel-making, oil refining, freight transport and shipbuilding. It is classified as a “Gamma -” level global city by the Globalization and World Cities Research Network, with some of the most prominent infrastructures in Taiwan.

The Port of Kaohsiung is the largest and busiest harbor in Taiwan while Kaohsiung International Airport is the second busiest airport in number of passengers. The city is well-connected to other major cities by high speed and conventional rail, as well as several national freeways. It also hosts the Republic of China Navy fleet headquarters and its naval academy. More recent public works such as Pier-2 Art Center, National Kaohsiung Center for the Arts and Kaohsiung Music Center have been aimed at growing the tourism and cultural industries of the city.
