The study investigates the effect of trade openness on the economic growth of agricultural countries. The information of export, import, gross domestic product (GDP), Gross Fixed Capital Formation (GFCF), and population of 72 agrarian nations generated by the World Bank from 2011 until 2020 is used for data examination. Then, before panel data analysis, a preferred model is chosen from among common-effects, fixed-effects, and random effects. The best model turns out to be a fixed-effect model. The result reports that from 2011 to 2020; 16 out of 72 nations have succeeded in experiencing positive economic growth, the value of GFCF was US$ 2,859.04 billion, and later grew by 19 percent to US$ 3,393.73 billion, the population tends to increase continuously year by year, and 2 out of 72 countries experienced export plus import exceed their GDP. Moreover, trade openness is positively associated with economic growth, with a coefficient of 3.81. Besides that, an increase in GFCF may boost economic growth by approximately 3.32 percent. On the contrary, one percent additional population significantly delivers around 25.46 percent negative economic growth. To sum up, the higher intensity of products or services sold and bought abroad may enhance the economic performance.

This research challenges the general notion of one-person households of the elderly during widowhood as impoverished, isolated, and vulnerable. Recognizing a high potential vulnerability, however, this research attempts to describe the diverse composition of one-person households of the elderly. For this purpose, relying on 2% sample data from the 2000 census, it examines regional distribution, socio-economic characteristics, and determinants of one-person households of the elderly during widowhood. Socio-economic characteristics of one-person households of the elderly differ by region. Jeju island is distinct in terms of sex and age distribution, and residence area of children. In general, rates of economic activity and self-subsistence are higher in provinces than in cities. Compared to the elderly living with family, the elderly living alone show high rates of economic activity, self-subsistence, and capability of physical activity. Results of logistic regression analysis of determinants of living arrangement are consistent with those of descriptive statistics. Those who are economically active and able to move around without assistance tend to live alone after the death of a spouse. Number of sons and living in an urban area are negatively associated with living alone, whereas females are more likely than males to live alone. According to the separate analysis by age, the positive effect of economic activity is greater in the oldest of the old than in other age groups. Those who possess high educational attainment tend to live alone when they are 80 and older, unlike other age groups. Based on these findings, this paper finds that one-person households of the elderly nay not always be the most vulnerable group, and are diverse in terms of socioeconomic characteristics.

Korean fisheries industry is surrounding by domestic and international difficulties due to the effectuation of the UN Convention on the Law of the Sea and declaration by many coastal states of 200-mile Exclusive Economic Zone and acceleration of ocean pollution in global recognition increasing of the importance of the ocean Resource enhancement policy in Korea fisheries industry is very important strategy fer the fostering of the fisheries resource and proper conservation and management of the coastal and off-shore living marine. Among resource enhancement policy, artificial reefs project has been the most effective strategy. The objectives of this paper are to find the economic effects of artificial reefs. The sampling artificial reefs is constructed at Suiido with 6~7m height. In order to analyze the fishing effect of artificial reefs, a few research have been conducted since 1975. For these analysis focuses on the side of scientific effect of artificial reefs, we analyzed on the side of economic effect. The results of the economic effects of artificial reefs are as follows ; First, the fishing effect analysis by using the NPV method in artificial reefs of Suiido ground prove to be economic feasibility. Second, the major socio-economic effect from artificial reefs include the increasing of recreation fishing, maintenance of fishing community, protection illegal fishing, conservation of coastal environment, and enlargement of advanced fisheries supply. Based on the above results, we conclude that artificial reefs project not only contributes to the welfare of fishermen by increasing of economic income, but enlarges to socio-economic gains by protection of illegal fishing and conservation coastal environment and so on.

As ten years have passed since national parks were adjusted and released inceptively, it is the time for evaluating the effectiveness of the national park policy and improving it on the basis of the evaluation result. In this study, the method of appraising the environmental and socio-economical ripple effect on the implementation of national park regulation were provided, based on the institutional consideration, the environment analysis, the survey of residents consciousness, the statistical analysis and so on. It is applied to target sites where were released from national parks, and the policy direction was suggested for sustainable use and management of national parks. National parks, that exhibit various characteristics depending on geographical and local conditions, were categorized through the statistical approach. Released sites from Seoraksan National park, where was categorized as the core national park for sustainable use and management, were evaluated environmentally based on the time-series analysis of environmental thematic maps and socio-economically based on the survey on residents perceptions. As a result of this study, the environmental effect of released sites has been declined or threatened, and the residents' economic, social and living condition in these areas are still not improved(p<0.05) since the adjustment of national parks. Based on the policy approach reflecting regional characteristics, natural resources are kept and enhanced for the sustainable use and management of national parks. And a consensus on the national park policy of national park should be developed between local residents and voluntary participation and public awareness should be attracted from them, based on the construction and the supplement of the infrastructure.

This treatise deals with chronic state of famine and exploitation of famine relief food in the later half of Chosun Period and especially in relation with socio-economic changes. There with the impact of socio-economic factors on the chronic state of famine and exploitation of famine relief food is studied mainly with a literary approach. The influential factors which lead to the chronic state of famine were not only climatic restrictions such as flood and drought but socio-economic factors such as foreign invasion (Japanease invasion and Ching's invasion), frequent breaking out of revolt and technological development of agriculture (rice transplantation). And disorder of land system and cultivation of cash crops by the richer peasantry, lowering the economic status of the poorer peasantry who were a major constituents of the population, aggravated the famine state. Because the poorer peasantry were under the shortage of food, they had to seek something edible in the fields and mountains. In this process various kinds of famine relief foods were exploited by the poorer peasantry. The majority of famine relief foods were wild vegetables. Consequently the Chronic state of famine was a cause to introduce various edible wild vegetables into Korean food, which influenced modern vegetarian food habits and firmed the Korean's favorite taste to be hot and salty. These wild vegetables couldn't have a marvelous effect on the relief of starved people. Potatoes and sweet potatoes, which were newly introduced foreign crops, were encouraged to be cultivated for famine relief. But these tubers, unable to be staple food, didn't contribute to an increase in population.

Purpose - The objective of this study is to investigate what motivates global FDI inflows in the different economic development level and to clarify the FDI motivation type in the level of qualitative economic growth. Design/methodology/approach - Major macroscopic social·economic factors induced FDI inflows were analyzed using fixed-effect panel regression with 30-year panel data of 28 countries from 1985 to 2014. For analysis in the stage of economic growth, two category of developed and developing countries was used. And to analyze FDI motivation type in the level of qualitative economic growth, 4 shares of GDP; consumption·government·investment expenditure and export, was used as explanatory variable. Findings - In developed country, TFP(total factor productivity) and GDP have a great influence on FDI inflows, and consumption and labor compensation have a slight effect. This result indicates that the market seeking-driven, horizontal type investment is shown along with efficiency seeking investment. In developing country, human capital and TFP is shown to have greater impact on FDI inflows and labor compensation, exports, investment and government expenditures also have impacts. Thus it has confirmed that not only efficiency-seeking vertical investment for using low cost well educated laborer, but also government-driven economic growth and export policies could affect the FDI inflows. Research implications or Originality - The FDI investment decision making of multinational companies is decided by their own purpose. But, in the concept of as follows; 1) FDI is a long-term capital flowing for maximization of economic utility with limited global resource, 2) Thus FDI could be affected by macro socio·economic factors of host country. 3) Also such macro factors is different by each economic growth qualitative level. Therefore macro socio·economic factors of each country could be affected by the qualitative level of their own economic growth. To attract FDI inflows, it is desirable to implement differentiated incentive policies in the qualitative level of economic growth. Furthermore in developing countries it is recommended to implement government driven economic growth policies as follows; fostering well educated human resources, improving technology productivity in the relative lower cost labor market compared to developed countries and boosting international export volume.
