The Korean dairy industry is facing challenges such as population declines, environmental regulations, market opening, high milk production costs, and shifting dairy product preferences. The article explores the US dairy system, which is focused on a differential pricing system for crude oil and a pooling method to calculate bonds, aiming to address income disparities among farmers. In contrast, Korea has a quota system, which has been criticized for shrinking the production base and is now under discussion for reforms to reduce milk production costs and enhance industry sustainability. There is interest in adopting a system that allows for autonomous milk production and trade, with a focus on sustainable dairy farming and practical policies based on advanced dairy country models.
