FTA 가맹국간 원산지 누적기준의 차별적 적용이 제품차별화 경쟁기업의 수출경쟁력에 미치는 경제적 효과에 관한 연구

초록

Purpose - This study examines the welfare effect of FTA member countries’ oligopolistic exporting firms which compete with product differentiation when the importing country’s government applies the bilateral or multilateral cumulation system. Design/Methodology/Approach - For this purpose, we introduced a two-stages game which described the importing country’s strategic behavior, and by using the backward induction approach, we attempted to solve the Subgame Perfect Nash Equilibrium(SPNE). Findings - Unlike the case of the exporting firms competing with homogeneous goods, in case a firm competes using product differentiation as its strategy, the importing country and high-cost firms’ welfare decreases, but the level of such loss is less than that of homogeneous ones. The deeper the level of product differentiation, the less the welfare loss in both bilatal and multilateral cumulation systems. Research Implications - To utilize the global value chain, it is best to accept multilateral cumulation systems. However, importing country and inefficient exporting firms of the FTA member countries suffer welfare losses, so they might oppose this. Thus, the results of this study would give important implications to logically persuade them in this case.
