The consumption of the domestic pork in Korea has been steadily increasing, although the price of the domestic pork has been higher than the one of imported pork. This fact implies that there might exist a certain degree of competitiveness in Korean hog industry. The competitiveness of hog industries was compared by using Poter(1990)'s Diamond Model between Korea and six different countries that have been the big exporters of pork to Korea in Korean pork market. Korean hog industry was found to have strong competitiveness in 『Demand Condition』indicating consumers may make their consumption decision based on "bounded rationality". In the mean time, 『Factor condition』 and 『Firm strategy, Structure, and rivality』 represented by production costs and productivity, were found to be low competitiveness factors to the Korean hog industry.
