Philippine regions have capital cities. So does each province. For instance, Koronadal, popularly known as Marbel, is the regional capital of Soccsksargen, and it is also the capital of South Cotabato.
However, the trading hub of the region is General Santos City, which hosts an international port and airport.
General Santos is a well-known case, and perhaps, a special one.
Other cities/towns are not well-known.
Here are other examples of trading hubs:
Solano, Nueva Vizcaya (population: 59,517 in 2015) is the main commercial and financial center of the province. It is home to the Nueva Vizcaya Agricultural Terminal, which trades vegetables. The capital, Bayombong (population: 61,512), is five kilometers (km) away.

Separated by less than 50 km, Santiago (population: 134,830) and Cauayan (population: 129,523) are the principal commercial centers. Cauayan hosts a city airport with connections to Manila.

Bayugan, Agusan del Sur (population: 103,202) is a key trade center and a major rice producer. It is also known for cutflowers. The capital, Prosperidad (population: 82,631), is 30 km to the south.
Trading hubs have emerged, independent of the capitals, in part due to their strategic location and resource endowments. Private sector dynamism is a major impetus.
