In the globalizing world, what are the determinants of fisheries income in South Korea? What should be considered and investigated before formulating, designing and implementing fisheries policies? Hwang’s research starts with a concise history of fisheries management before and after colonialism based on a literature review and proceeds with the analysis part using an econometric model and quantitative analysis. This study essentially focuses on finding the relationships and degree of influence of four important factors – resource depletion, operation costs, wages, and fish prices – on fisheries income.
