Release Information

The Industrial Production Index (IPI) measures on a monthly basis the change in output in South Korea's mining (B), manufacturing (C), electricity and gas (D), and publishing (58) industries. Output refers to the production of goods and generation of power for domestic sales in Korea and for exports. The index is helpful in illuminating structural developments in the economy.

For South Korea, monthly IPI is reported by both the NCB and NSI, on slightly different schedules.

Production, shipping and inventory performances per items are utilized as basic data for major material demand and supply and projection.

To prepare operation rate index indicating production capability index and equipment usage rate indicating supply capacity level by surveying production capability, etc. of major products in manufacturing industry area.

  • The data in the press release are preliminary and are subject to revision during the next two months. The data become final about three months after the end of the calendar year and are published in the Annual Report on Monthly Industrial Production Statistics.
