        The purpose of this study is to develop promotion strategies for revitalizing mountain eco-villages through social economic support. In order to fulfill this purpose, this study analyzed operation conditions, income creation structures of 240 mountain eco-villages formed by Korea Forest Service, and reviewed systems for social economic support. As summarized in research outputs, this study confirmed that the activities of organizations for joint projects had not been properly implemented due to the absence of supporting systems following the construction of mountain eco-villages. In addition, 159 villages formed as experience villages could not be qualified for enterprise systems due to aging population and absence of network systems. As for income creation, as indicated by comparing net incomes for joint projects calculated based on the classification of village management evaluation, the average net income of 51 highly-rated villages was 22 million Won and that of 128 moderately-rated villages was 3.5 million Won. Experience-based projects and the sales of processed forestry products made by young adult associations or women's societies were major sources of income, and the absence of inner economic bases or villages' jobs caused young adults and returned farmers to focus on working for outside economic activities. Finally, this study developed strategies for mountain eco-village's social economic promotion and suggested four stages of social economic revitalization provisions.

        This study aimed to categorize mountain villages according to business expense investments and investigate residents' supplementation demands and differences between expected effects by the categories. For the study, 35 villages where are completely developed on and after 2007 were selected to consider fairness among local governments. Each village leader(the head of the village or the chairperson of the management committee) was conducted a survey from 2012 May to August and one copy of survey was eliminated from the study. The study is summarized into four results. First, the types of mountain villages were categorized as a type of mountain village practice(18), a type of life environment improvement(8) and a type of forestry income(8) according by the itemized reports of the business expense investments. Second, the result of F-test(One Way ANOVA) for the average analysis by types showed that 3 out of 6 demands for the operation were significant differences and a supplementation necessity of the program was identified significant differences in p<0.01 level. The necessity of forestry resources use and sprawling development prevention are also showed significant differences among types in p<0.05 level. Third, F-test results from 7 questions of desired effects through mountain village creation project revealed that promotion and market security of forestry products and local patriotism instillation through a personal exchange are significant differences between types in p<0.05 level. Forth, the results of duplication benefits(the mountain village development projects and the village support programs with other departments) on the residents' development expectation found that when a village received a large number of projects, residents' expected effects were higher than other village residents where received relatively a small number of projects. However, the expected effects from the increasing quantities of projects were decreased.
