What Are The Biggest Industries In South Korea? - WorldAtlas

ShipbuildingAutomobilesMiningTourismThe Four Asian TigersIn the early 1970s and 1980s, Korea emerged to be one of the worldleaders in shipbuilding, oil supertankers, and other oil drilling platform. The largest shipbuilder in the country was Hyundai which in the mid-1970s build a one-million-ton capacity drydock at Ulsam. Another major player in the shipbuilding industry is Daewoo, which in the 1980s managed to produce a 1.2 million ton facility at Okpo. However, in the early 1980s, the industry experienced a decline because of the global recession and oil glut, but in the late 1980s, there was a sharp increase, and in 1988 total orders of ships from Korea were valued at $1.9 billion. By the 1990s, shipyards in South Korea tripled their shipbuilding capacities and by 1999, the country had achieved global market leadership in shipbuilding. By 2008 the country was the world’s leader in shipbuilding, accounting for 50.6% of the Global market share.
