Incheon forms the heart of Capital Industrial Region. During the industrialization of South Korea, several industrial complexes were built throughout the city, and as a result, the city was largely dependent on manufacturing industry. But with the designation of Incheon Free Economic Zone in 2003, the city is now making an effort to foster new growth industries. Major industrial parks include Bupyeong industrial complex, which hosts GM Incheon plant(formerly a GM Daewoo Incheon plant), Juan industrial complex, and Namdong Industrial complex.
In recent years, bio industry is emerging as a new growth industry of the city. Currently, with the total production capacity of 330k per year, the city ranks 2nd in the world by production capacity along with San Francisco, United States. The capacity is under expansion, and after completion in 2018, the city will rank 1st with the production capacity of 510k. Also, logistics industry is also experiencing a rapid growth, thanks to Incheon Airport, which was ranked fourth in the world by cargo traffic, and the expansion of Incheon Port.
Incheon's sea port is the second largest port in Korea after Busan's sea port.
The International Passenger Terminal located at the port offers ferries to five cities in China: Dalian, Qingdao, Tianjin, Dandong, and Weihai. There are also ferries to Incheon's outlying islands as well as Baengnyeong Island inside of the Northern Limit Line.
Incheon Bus Terminal, located at its eponymous subway stop, offers express bus transportation to all parts of Korea. Many city bus lines offer transportation within city limits as well as to the neighboring cities of Bucheon, Gimpo, Seoul, and Siheung.
Many BRT lines offer transportation between Seoul and Incheon.
Local service to Guro, Seoul, Cheongnyangni, Uijeongbu and Soyosan is offered by Seoul's subway Line 1. The line has 11 stations within Incheon and connects to the Incheon Subway at Bupyeong and Juan stations.
Rapid service on the same line to Yongsan Station in Seoul depart from Dongincheon station and stops at major stations.
The Airport Express (AREX) line runs from Incheon International Airport to Seoul Station via Gimpo International Airport. The Incheon-Gimpo section was opened in March 2007 and was extended to Seoul station in December 2010. Passengers can choose a high-speed service stopping only at Incheon airport and Seoul, which takes 43 minutes but departs only every half-hour; or the all-station service which takes 53 minutes but leaves every six minutes.
KTX service was introduced on the AREX line on 30 June 2014, with stops at Incheon International Airport Station and Geoman Station. There are additional plans to use the newly built Suin Line to bring KTX service to Incheon Station by 2021
