Until now, research on inter-Korean economic cooperation and economic integration has been limited to the areas of the two Koreas. However, Korea is connected with many countries in Asia through the global value chain. Thus, if inter-Korean trade deepens, it may affect the trade structure of neighboring countries. In order to establish a specific inter-Korean economic integration policy when North Korea becomes a normal state in the future, an analysis that reflects the trade structure including Northeast Asia must be preceded. Therefore, in this paper, the impact of inter-Korean trade on Korea, China and Japan was analyzed using the international input and output table containing actual trade data. The scope of analysis was limited to agriculture, reflecting North Korea's demand for economic cooperation. The results show that trade in the agricultural sector between the two Koreas did not have a significant effect of production and value added. but when China and Japan participate in trade with North Korea, the production effect was calculated to be as high as 4 million dollars in Korea and up to 10 million dollars in Japan. And China showed up to 520 million dollars. In addition, the value-added effect was calculated up to $1 million in Korea, up to $4 million in Japan, and up to $250 million in China.

The purpose of this study is to verify the economic effects of the on going Korea-EU FTA negotiations upon the regional economy and to present some strategic economic countermeasures to deal with the forthcoming changes on the economic environments. In comparing with the industrial structure between Korea and EU, due to the different specific part of their industrial competitiveness both parts would have complementary cooperative transactions and trade as well. And also Korea and EU would have the similar understanding of the importance of the field of agriculture and service in accordance with the economic standpoint respectively. The level of degree and magnitude of the effect of Korea-EU FTA upon the regional economy would be decided in accordance with the industrial structure and the level of income of the regional economy. We are not to confirm and specify the economic influences of Korea-EU FTA negotiations on the economic conditions of Gangwon province but to prepare rational economic countermeasures fit to its structural character. One of the political strategies that might be feasible is the inflow of foreign direct investment from the developed European countries to the regional economy. This developing model would mean a new experiment to activate any regional economy and a new formation of the policy of economic growth.

This study deals sith some problems of foreign direct investment and seeks for the ways of activating foreign direct investment (hereafter F.D.I.) by analyzing the Korean economic structure that is faced with the neo-protectivism and nationalism of the advanced or foreign countries currently. During a transformational process in the transitional period of world trade environment, it is necessary for Korea not only to learn the higher technology for advanced countries, but also to apply techonology to their economic structure in order to enter into competition with the advanced countries. Based on the experiences and accomplishments from their investments, Korean enterprises should turn their business into F.D.I. and act appropriately in order to keep the balance between indoor and outdoor investment. Looking through the ways to activate F.D.I., we may make conclusions as follows: 1. Government policy transparency 2. Prudential Macro Economic policy 3. International policy coorperation system 4. Solidification of Foreign Commercial intercourse to Developing countries 5. Globalixation base of domestic coorperation 6. High efficiency- low cost of business coorperation enterprise 7. Attacktive investiestment strategies on conclusive competive advantage 8. Multilateral investment Area 9. New recognixation on marketing investment etc. F.D.I. strategies

This study is to analyze the economic effects of tariff reduction using computable general equilibrium(CGE) model. We set up the social accounting matrix for five-base equilibrium year. Our main findings are as follows. First, the impact of tariff reduction on GDP was different from time to time. It meas that the differentiated economics structure was affected by tariff reduction. As our economic grew up, the impact of tariff reduction was measured much higher. Second, until 1995 the impact of tariff reduction on total export and import was increased, then while 1995 the increase was dropped. This is because we reduced the tariff by the WTO negotiations. Third, the tariff reduction affected the price of imported goods, so it contributed to substitute effects between domestic and imported goods. According to these results, we found out the importance of the linkage between the tariff reduction and economic structure.

The Korea Offshore Wind Power (KWOP) cooperation is planning to construct offshore wind energy farms with an overall rated power of 2.5 GW along the southwestern coast by 2019. Hitherto, various structural types of support structures for offshore wind turbines have been being proposed, but these structures have lacked economic analysis studies. Therefore, their economical superiority to existing types has been difficult to guarantee. An offshore structure with economic efficiency will have a minimum amount of mobilizing equipment and short offshore construction period because of the application of rapid installation methods. Thus, the development of a new support structure with economic efficiency is generally considered to be necessary. Accordingly, this paper proposes a newly developed and more economical jacket type for the offshore support structure. This study confirmed its structural safety and performance by conducting a structural analysis and eigenvalue analysis. The manufacturing and installation costs were then estimated. As a result, the new jacket type of offshore support structure proposed in this study significantly reduced the manufacturing and installation costs. Therefore, it is expected that the proposed jacket will contribute to reducing construction expenses for new wind power farms and invigorating wind power farm businesses.
