The shipbuilding industry is one of the most important manufacturing and pillar industries in South Korea, and also a major exporter of foreign trade, bringing huge trade surpluses to South Korea every year. In recent years, the export value and foreign trade surplus of South Korea's shipbuilding industry have consistently ranked first among the seven major export industries in South Korea. In 2010 and 2011, the export value of ships was $46.7 billion and $54.1 billion, respectively. In 2012, the export value of ships dropped to below $40 billion. Therefore, the trend of the shipbuilding market affects the sensitive "economic nerves" of South Korea. At the end and beginning of each year, the "ups and downs" of the shipbuilding market have become hot topics for analysis and prediction in the South Korean industry.
