Purpose - The object of this paper is to ascertain how Japan has become a powerful trader in the international grain market. A case in point is the world's third largest U.S. major grain trader, Gavilon, merged with general trading company Marubeni in 2012. What are Japan's strategies and their implications? Research design, data, and methodology - The study analyzed Japanese Ministry of Agriculture, Forestry, and Fisheries data, and data from daily and weekly papers. The paper employed various data and research methodologies. Results - The Lee Myeong-Bak government tried for three years to create a company similar to Cargill, but the project eventually failed. On the other hand, Japan has emerged as a leader in the international grain distribution market for the past 50 years, with the cooperation of government and private companies. Conclusion - The findings of this study show that Korea, China, India, and other countries' international major grain companies now compete to be powerful, major grain traders. South Korea could be the leader of the international grain market through the development of a more careful and long-term strategy.

본 연구는 최근 들어 시장의 불완전 경쟁 구조에 따른 시장 불안정 상태에 대한 우려가 가장 크게 제기되었던 시장인 곡물 교역시장에서의 연도별 불완전 경쟁의 수준과 함께 그 동태적 변화추이를 분석하였다. 기존의 시장구조 접근법에서 많이 사용되어왔던 상위 k개 국가 중심의 집중률 (Concentration Ratio: CRk)지수의 곡물 교역시장 분석상의 한계점을 명시하고, 이에 대한 대안으로 로렌츠 곡선 개념을 도입함으로써 전체 국가들의 분포적 특징을 분석하였다. 이를 바탕으로 지니 불균등 지수 (Gini Inequality Index)와 엣킨슨 불균등 지수 (Atkinson Inequality Index)를 활용한 통계적 분석을 수행하였다. 실증적 분석결과, 연도별 수출과 수입간 불균등도 차이는 분석기간 내내 통계적으로 유의수준의 양의 추정치를 나타내었다. 또한 2002-14년 기간 동안 이러한 불완전한 경쟁 상태는 2001년에 비해서 전반적으로 심화되었다. 수출 집중도가 일반적인 인식과 달리 소폭이나마 하향세를 나타내고 있음에도 불구하고 곡물 교역시장의 불완전 경쟁상태가 심화되고 있는 것은 수입의 국가별 분포가 수출의 경우 보다 현저하게 균등화되고 있기 때문으로 보인다.

The paper analyzes GMO legal system and the problems of its management in China and their suggestions to Korea. GMO has been arising as a principal alternative of grain while grain prices continue to climb. Although there has been concerns about GMO imported from China, it is true that we have not studied on China's legal system and the problems of its management in China. The paper believes that when Chinese government does not manage GMO primarily, we have a high possibility that China's GMO food will access to Korean market at any time, and threaten our health and safety. Hence, it is highly time to analyze how legally China treats GMO and what the problems of its management are. The paper found out problems of China's GMO management in three ways. Firstly, GMO legal system of China is confused and it has limitation of effectiveness. China has no regulations like "a law" to regulate GMO and regulations which exists now are not easy to apply in substance. Secondly, China has no administrative strictness to manage GMO. For example, the regulation which ministry of agriculture in China promulgated in March of 2002 started to use partially since 2003, 7. Thirdly, China, as a nation that administration superiors to, market does not do its roll to control GMO. It relates to the low concerns and care of Chines people about GMO. The paper shows suggestions and countermeasures according to problems of China's GMO management.

In this study, the relationship between Baltic Dry Index(BDI) and maritime trade volume in the dry cargo market was verified using the vector autoregressive (VAR) model. Data was analyzed from 1992 to 2018 for iron ore, steam coal, coking coal, grain, and minor bulks of maritime trade volume and BDI. Granger causality analysis showed that the BDI affects the trade volume of coking coal and minor bulks but the trade volume of iron ore, steam coal and grain do not correlate with the BDI freight index. Impulse response analysis showed that the shock of BDI had the greatest impact on coking coal at the two years lag and the impact was negligible at the ten years lag. In addition, the shock of BDI on minor cargoes was strongest at the three years lag, and were negligible at the ten years lag. This study examined the relationship between maritime trade volume and BDI in the dry bulk shipping market in which uncertainty is high. As a result of this study, there is an economic aspect of sustainability that has helped the risk management of shipping companies. In addition, it is significant from an academic point of view that the long-term relationship between the two time series was analyzed through the causality test between variables. However, it is necessary to develop a forecasting model that will help decision makers in maritime markets using more sophisticated methods such as the Bayesian VAR model.

Our self-sufficiency of food has become less than $30{\%}$ and our nation is highly dependant on world's grain market for food. which is unstable in long term due to the world population growth faster than food production. Therefore, it is a great possibility that food might become a political weapon by way of its global shortage. its purchasing difficulty in international free trade market. and the resultant price rising. Our maximal capability of food production has become the most outstanding problem in the dimension of future food security. It would be the utmost scheme for maximal production of food to realize the maximal utilization of arable land through the enlargement of sufficient farming land and the conversion of rotation system for the more grain production. Extensional enlargement of arable land can be positively executed through the development of farming land in domestic and abroad countries. The readjustment of arable land and the installation or irrigation and drainage system can enforce the farming basement for maximal utilization of arable land through the improved rotation between paddy and upland. The prevention policy against farming land encroachment should be strictly executed through grain production encouragement on resting or marginal lands and regulation of utilization conversion for the other than food production on high grade farming lands. It is also required urgently to develope high yielding and high quality varieties through advanced genetic technology for the improvement of unit area yield, especially of wheat, corn. and soybean we import in large quantity The maximal utilization of arable land for the highest production of food can be realized through rational rotation system, the most adaptable crop cultivation on the suitable land, and the most optimal fertilization through the GIS analysis of agricultural environment information on the basis of the computerized soil resource data on super detailed soil maps(1:5000) surveyed plot by plot of whole nation.

Purpose - The purpose of this paper is to analyze the relationship between the real exchange rate and the output, which is based on the macroeconomic equilibrium theory in China. Its aim will be to verify whether the change in the real exchange rate has a significant effect on the output or not. Research design, data, and methodology - This study endeavors tries to investigate the correlation among economic variables under the macroeconomic market (the commodity market and the money market) equilibrium. So, time-series data from 1990 to 2016 is applied to establish a vector auto-regression (VAR) model so as to perform an empirical analysis. Results - The empirical results reveal that an increase in the real exchange rate will result in an increase in the output in the short run. However, the empirical results also indicate that this kind of mechanism cannot work in the long run. Conclusions - The effect of a decrease of real exchange rate on output is significant in the short run. Also, this paper suggests that the total supply and the total demand can promote economic growth. The fiscal and money policy play a significant role in economic growth in China as well.

Many reclaimed tideland projects in Korea have been conducted to secure the food self-sufficiency. In fact, the domestic food self-sufficiency has been greatly improved and reclaimed tideland projects contribute to Korea's economic and social development directly or indirectly replacing agricultural lands from urbanization, industrialization. As result, current self-sufficiency of rice reach the demand(104.6%) while rate of upland crops has less than 30% of self-sufficiency rate and corn, wheat, soybeans, etc. are virtually dependent on imports. Domestic price of crop is expected to be unstable by trend of international grain prices. Therefore, developing reclaimed tidelands as upland which is originally constructed for paddy fields could be a good option to become steady in domestic crop market and dedicate to ensure a stable food security. The study to prepare measures for dealing with disasters in reclaimed tidelands of west coast district is required in order to utilize those sites for infra construction of multi-utilization in those sites and The result of flooding analysis in this study can suggest policy direction for practical utilization of reclaimed tidelands in yellow sea area.

이 논문은 연변지역의 농업 변화과정을 일제시기, 사회주의시기, 개혁개방시기 등 3개시기로 나누고 각 시기 연변지역의 농업이 외부환경의 변화에 따라 어떻게 시계열적으로 변화 발전되어 왔는지에 대해 살펴보았다. 그 결과를 요약하면 다음과 같다. 첫째, 일제시기 연변의 농경지는 이민정책, 자작농창정, 집단부락건설 등의 형식으로 일제의 수중에 집중되면서 자신들의 전쟁 수요와 국내 수요에 따라 농작물 재배를 통제할 수 있고 또한 농작물을 마음대로 약탈 할 수 있는 기반을 마련하여 전형적인 주변부 특징을 띠고 있었다. 둘째, 사회주의 시기 연변지역은 농촌의 인민공사화를 실현함에 따라 토지는 전부 국가소유로 되었다. 이와 같은 토지의 국가 소유는 농업생산에 있어 강력한 국가의 개입을 가능케 하였다. 그리하여 당시 계획경제체제 하에서 농업생산은 시장 논리에 의해 좌우된 것이 아니라 식량생산만을 중요시하는 '이양위강(以糧爲綱)'정책의 영향으로 농업 내부에 있어 경작업만 중요시하고 경작업 내부에서도 식량생산만을 중요시 하여 풍부한 자연자원을 효과적으로 이용할 수 없게 되었다. 셋째, 개혁개방 이후 농촌에서 호도거리책임제를 실시함에 따라 농민들이 토지를 장기간 임대할 수 있게 되어 농민들의 생산의지가 크게 고양되었다. 게다가 사회주의 상품경제에서 시장경제체제로 전이함에 따라 시장의 수요에 따라 농작물을 재배할 수 있게 되었다. 그리하여 연변지역의 농업은 전통적인 식량작물 생산 위주에서 점차 다각화 방향으로 발전하게 되었다.

This study investigates the impact of International Monetary Fund(IMF) Age on the household behavior of food consumption and analysis the related factors(demographic variables, family life style) to find out the reasonable consumer's consciousness and food market conditions. The results are as follows. 1. General life style and food life style, considered as family life style, were classified into 7 types and 9 types respectively as family life style by factor analysis. 2. The rationality of using and disposing stage on food life has increased, the rationality of the planning stage on food life has decreased since the IMF age began. But the rationality of overall food consumption has hardly changed. 3. The amount of purchasing was decreased, discount store was favorite place to buy food, and safety and freshness were major determinants in purchasing for most of food items. But this was different with food items. The various information sources were used impartially to buy food, cash was used mainly, and the degree of using the discount ticket/coupon was a little low. 4. Income level is an influential factor on the rationality of the planning and purchasing stage on food life, while environment-oriented food life style has influenced on the rationality of using and disposing stage. The purchasing amount of grain products, meats, milk products, bread and snacks, drinks, alcoholic drinks, water and convenience goods has influenced by demographic variables, eating out had been influenced by general life styles, and fruits, healthy foods, processed foodstuffs, favorite foods, vegetables seaweeds, import foods and seafood had been mainly influenced by food life style since IMF age began.
