Under the WTO system, the farm size expansion or the existing korean agricultural structure should be improved to cope with farm income decrease and to continue rice cultivation for food security in the future. This study is aimed at identifying optimum farm size under trade liberalization and import and export parity price system of inputs and outputs. The optimum farm size expressed the minimum point of long run average cost is determined as 15.1ha. The farm size to be equalized as urban laborer's income of 37,361 thousand won per year was revealed 30ha. Therefore the G't recommended farm size of 6ha should be changed to 30ha and the concerned policies for agricultural structure improvement also should be changed to more flexibilitiy.

The present study aims to provide an analytical framework for achieving aid and development effectiveness of agricultural cooperation with a demand-oriented perspective. This paper pays particular attention to categorize the stages of agricultural development of African recipients to identify demands for agricultural aid of the categorized groups. To do so, first of all, it establishes theoretical background to apply the demand-oriented concept and utilize the phase of agricultural development as an alternative for aid and development effectiveness. On the basis of the theoretical robustness, it conducts a series of analyses to categorize the African recipients by the development stages, incorporating factor analysis, cluster analysis and comparison between the present-future agricultural development levels. The findings propose analysis indicators for phase of agricultural development and clustered results including 18 countries of KAFACI members and priority countries in Africa. In addition to the practical application of the results, the methodological flow can be used as steps for sketching a future roadmap to construct the demand-oriented ODA(Official Development Assistance) plan. This paper also offers implications regarding ODA strategy of Korea in response to the phase of agricultural development and the aid demands.

본고는 에너지부문을 세분화 한 한국경제의 KELM DB를 구축하고, 다양한 중첩(nesting) 구조 하에서의 CES 생산함수를 추정하여 투입요소 간 대체탄력성을 구한다. KLEM DB는 투입요소가 자본, 노동, 에너지, 중간투입재로 구성되는 산업별 수량지수 및 가격지수로서, 이 중 에너지투입은 전력, 가스, 석유, 석탄으로 세분화하여 에너지 투입의 변화를 나타낼 수 있도록 하였다. 구축된 KLEM DB를 바탕으로 CES 생산함수의 중첩구조별로 투입요소 간 대체탄력성을 추정하였고, 대체탄력성 추정치를 사용하는 CGE 모형의 관례대로 중간투입재와 여타 투입요소 간의 Leontief 결합을 가정하는 경우와 이 가정을 사용하지 않는 경우 모두에 있어 대체탄력성을 추정하였다. 본고가 제시하는 탄력성 추정치는 산업별 생산기술 구조와 생산성 분석뿐 아니라 기후정책의 효과분석, 일반균형모형의 구축 등 다양한 연구에 활용할 수 있을 것으로 기대한다.

The paper is to analyze multi-attributes for expanding new renewable energy in agricultural sectors which have environmental, technical, economic, and social factors consisting of 15 attributes which have both positive and negative impacts. We applied the analytic hierarchy process (AHP) to data from opinion polls. As a result of the AHP survey, the overall results indicate that the respondents more weight on economical factor than environmental, technical, and social factors for expanding new renewable energy. At the lowest level, a comparison of individual 15 attributes within three factors shows that fixed cost highest in multi-attributes, followed by operating cost, technical superiority. To achieve the public acceptance about expanding new renewable energy in agricultural sectors, the policy-makers should take all relevant factors into account through the decision-making process by the public opinions.

The objective of the this study is to find a way to increase fm household income through investigating their computer applications. We utilized the 2000 Korea Agricultural Survey data and applied a Heckman Selection Model to correct a selection bias. The present study found the following results. First, determinant of income among fm households by the level of computer applications has significant statistical differences based on their choices of computer applications. Accordingly, the application of general linear regression about fm income without adjusting these choices may cause statistical fallacy. Second, it has been reported that increasing the member of household is not directly related to increasing the fm income. In case of computer-own farm household, the effect of decrease in income according to increasing in age was predicted. However, in the fm household not possessing computer, it shows negative relationship. It shows that an agricultural career of farm owner and educational attainment of all farm household members have positive relationship regardless of computer possession. The income of the farm household those main field is not agriculture is also found to be lower than that of farm household whose major earnings come from agriculture.

The Ministry of Agriculture, Food, and Rural Affairs is currently pushing forward policies targeting the Rural Convergence Industry initiative to incubate the front-runners of the '6th industry', to increase off-farm income, to create rural jobs for elderly, and to create women-based farms. As a result, in 2017, a total of 11,604 Rural Convergence Industries were in business, and the goods produced from those industries were diverse. However, the quality and safety of those products are not being checked and managed thoroughly, which has caused consumers to not trust products made from the Rural Convergence Industries. Through a survey and the ordering logit model, this study analyzed consumer perception of the safety and quality of goods from the Rural Convergence Industries. The analysis revealed that we must first raise awareness of the importance of rural agriculture areas and the products of the Rural Convergence Industries to uplift consumer perceptions regarding the products produced by the industries. The analysis also revealed that diverse points of distribution (sellers), education on the importance of rural and urban areas, and marketing Rural Convergence Industry products within suburban consumer populations are necessary to increase the consumption of these products.

We devised a grape variety model to estimate the impact of lowering the Shine Muscat quality level on the grape market. Shine Muscat has become a popular grape variety in Korea. Accordingly, the area devoted to the harvesting of Shine Muscat has increased dramatically since 2016. Our study examines how a reduction in the quality of Shine Muscat affects other grapes such as Campbell Early, giant peak, and Muscat Bailey A (MBA). The Armington model was used to impose consumer preferences and product differentiation assumptions. We found that a decrease in the consumer preference for Shine Muscat realized by lowering the quality of Shine Muscat largely reduces the price of this variety. Also, the prices of other grape varieties fell via a substitute effect. Moreover, if grape varieties were more differentiated, the reduction in the price of Shine Muscat would be greater, while the decreases in the prices of other grape varieties would be smaller. These results imply that farmers of Shine Muscat must continue with quality management efforts to avoid the negative effect of changing consumer behavior with regard to Shine Muscat against a reduction in its quality. Our model introduces a product differentiation model for the fruit market and helps policymakers and farmers understand the impact of changing market conditions in the fruit market.

This study aims to examine the structural relationship between consumers' health-related lifestyle. purchasing attitude and purchase intention in the rice-based bakery products market. Data were collected from 397 consumers in their 20 years old and more. Results showed that purchasing attitude positively affected nutrition, trends and taste, and it was a key variable in explaining the intention to purchase rice-based bakery products. Therefore, it is necessary to develop and cultivate rice flour varieties containing various nutrients and develop products by capturing the food trends among consumers to induce them to purchase rice-based bakery products. Purchasing attitude fully mediated the relationship between taste and purchase intention, which suggests that it is necessary to hold tasting or sampling events and carry out promotional activities for consumers to perceive that rice-based bakery products taste good, which may lead to positive purchasing attitude.
