Jinhae has developed to the planned naval port city since Japanese naval ships anchored here after the Japanese invasion in 19th century. This is the first planned city of the radial road net constructed after the Japanese naval flag. Having the educational institutes of the army, the navy and the air forces and the navy headquarters after the independence and the Korean War, Jinhae continued to develop into the military city.

Although it is adjacent to Masan and Changwon, Jinhae was rather late in the development of the industries due to the feature of military city, except Jinhae Chemical fertilizer plant built in 1967. However, since 1987, when the navy headquarter law was loosened, Jinhae could build tall buildings. It also built the national industrial complex in Jinhae and Macheon and housed the shipbuilding-related industries. Jinhae is now expecting the development of factory land in Yongwon District following the construction of Noksan Industrial Complex in Busan. In December, 2005, the number of companies in Jinhae was 8,829 and the employees numbered 38,135. In 2006 alone, total trade amount in Jinhae recorded US$2,008 Million with US$1,443Million in exports and US$ 625 Million in imports.

Recently, Jinhae is vigorously facilitating the Jinhae New Port project and Free Economy Zone project to vitalize local economy and increase employment through balanced development of the nation.
