In 2023, the Seoul Metropolitan Area's gross regional domestic product was US$ 1.0 trillion, generating around half of the country's total GDP. It is the fourth-largest urban economy in the world after Tokyo, New York and Los Angeles but ahead of Paris and London. The region hosts headquarters of 59 Forbes Global 2000 companies. As the economy of Seoul Metropolitan Area transformed to knowledge economy from the manufacturing-based economy of the 20th century, there are a number of high-tech business parks in Seoul Metropolitan Area, such as Digital Media City and Pangyo Techno Valley.

The Seoul Metropolitan Area is home to the most affluent and livable cities and apartments in Korea but there are significant discrepancies between cities and districts, particularly between those built in the older and newer generations. Newer areas with more modern and luxurious apartments and infrastructure are more expensive, along with proximity to Gangnam District, the commercial center of the region.
Government
Various agencies have been set up to deal with the intergovernmental problems of the region. Proposals for consolidating some or all of the cities of the capital area into a handful of metropolitan cities have thus far not been implemented.
Development in the area is currently governed by the Capital Region Readjustment Planning Act (), first passed in 1982 and last revised in 1996.
Subdivisions


The Seoul Metropolitan Area is divided among the special city of Seoul, the metropolitan city of Incheon, and province of Gyeonggi. Seoul has 25 gu (local government wards), Incheon has 8 gu and 2 counties, and Gyeonggi Province has 28 cities and 3 counties as the subdivisions.

Transportation
The cities of the capital area are tightly interconnected by road and rail. Many of the country's railroad lines, most notably the Gyeongbu Line, terminate in the region. In addition, rapid transit is provided by the Seoul Metropolitan Subway, which has lines that serve all districts of Seoul, as well as the city of Incheon and other surrounding cities within Gyeonggi Province.
The region is a nexus for travel by air and water. The country's two largest airports, Incheon International Airport and Gimpo International Airport, are in the metropolitan area. International and domestic ferries depart from Incheon's ferry terminals several times a day.
Seoul Ring Expressway (Expressway No. 100) connects satellite cities around Seoul.
