시장규율을 위한 수입 자유화와 관세율정책

This paper explores the role of tariff policy to nurture competitive market structure of the type in developed countries in time when our large indu- stries accomplished international competitiveness. The government has so far adopted developing countries' tariff policy for the sake of economic growth and as a result monopolistic market structures are prevalent in our economy and consumers endured high priced products for long time. Also, outside shocks are reflected in price without adjustment, aggrava- ting high cost structure. This study therefore examines theoretically import liberalization's impact on price level to find out the important characteristics of product pricing behavior and the relationship between domestic and import price. It also explores major countries' tariff system. The study shows that import and imperfect competition correlates with price level and especially product's characteristic exerts profound effect on pricing based on monopolistic competition. Ultimately, in order to break down imperfect competition and to promote competition, tariff needs to be lowered for consumption products of large firm such as food and drink or electronics. This means policy shift from equal tariff to differentiated tariff based on product in concern. This will not produces immediate price fall down but it will in the long run help our economy to accomplish price stabilization by inducing competition and encourage our industries in maintaining international competitiveness by lowering production cost.
