This study predicts the economic activity level of the elderly in Korea using various machine learning methods. While the previous studies mainly focused on testing the relationship between the economic activity level and the life satisfaction or the social security system, this study aims at the accurate prediction on the economic activity level of the elderly using various machine learning methods and the forecast combination. Dependent variables such as the activity rate, employment rate, etc and independent variables such as the income, average wage, etc compose the dataset in this study. Five different machine learning methods and two forecast combinations are applied to the given dataset. The prediction performances of the machine learning method and the forecast combination varied across the dependent variables and prediction intervals, but it was found that the forecast combination was relatively superior to other methods in terms of the stability of prediction. This study has significance in that it accurately predicted the economic activity level of the elderly and achieved the stability of the prediction, raising practicality from a policy perspective.

The purpose of this study is to check effects on the awareness of parents supporting in their self retirement preparation of the baby boomer generations who have faced relatively bad situation in this era considering the reality of great changes brought in the parents supporting spirit which was regarded as family and individual responsibility due to the rapid industrialization and urbanization. In the result of this study, some points such as religious, living status and monthly average earning show meaningful result and also all of the colligation in the retirement preparation standard concerning economic living life, health life, leisure time, family life, dwelling life and leisure life shows most significance probability of .001(*p<0.05) and retirement preparation standard relative to economic life indicates significance probability of .005(*p<0.05). Eventually this result shows that the higher people have retirement standard, the higher parents supporting sprit they have. So I would like to suggest some policy advices on the basis of this study. First stable supporting policy on their dwelling life should be assisted by differential methods, secondly social programs aid for leisure life through social activities like volunteer work are required, further more national based policy supports for youngsters are considered in order to reduce economic daily life on their economic activities.

Innovation is not only one of the factors determining the competitiveness of national regions, but also an engine for economic development, and plays an important role in breaking out of the trap of middle-income countries. This paper constructs a regional innovation index from the perspectives of innovation input, innovation output, and innovation environment, and measures the regional innovation index of 31 provinces, municipalities, and autonomous regions in China from 2006 to 2019 by using principal component analysis and cluster analysis. The results concluded that there are large provincial and municipal differences in China's regional innovation capacities, and the provinces with higher comprehensive levels are mainly concentrated in the southeastern coastal region. Cluster analysis divides the 31 provinces, municipalities, and autonomous regions into five types, and the results find that the respectively developed coastal regions are in the high-level and the high-level regions relying on the advantages of location and national policies.

Recent migration is led by skilled labor, This paper performes a cross-country analysis to find the determinants of skilled migration using recently released Doquier and Marfouk(2005) data as dependent variable and economic indicators of nations as independent variables. Regression results show that the skilled migration to OECD countries are driven not only by income motive but also by structural factors, such as industrial structure and life expectancy, which have broader meanings in development. It is noteworthy that structural factors of a nation become more important as its income level rises. English seems to have positive effect on skilled migration. Some region-specific factors, proximity to USA of Caribbean countries and political instability of Gold Coast countreis, for example, are found. Middle-income countries seem to be the most vulnerable to the possible risk of brain drain.

복잡한 시스템의 악순환 고리를 끊는다는 것은 많은 어려움과 또 다른 구조적인 문제를 초래할 수도 있다. 우리나라의 수도권과 비 수도권간의 격차 문제는 복잡한 시스템의 악순환 구조를 보여주는 대표적인 사례일 것이다. 수도권으로의 정치, 경제, 사회적 집중과 상대적으로 비 수도권 지역의 과소·소외 상황은 어세, 오늘의 문제가 아니라 지난 40여년 이상 누적되어 온 과제라고 할 수 있다. 수도권의 집중이 가속화되는 동안 정부는 이를 완화시키기 위하여 각종 조치를 취하여 왔다. 그러나 수도권으로의 기능 집중은 지금도 진행되어 오고 있으며, 정부의 관련 정책들의 효과는 상대적으로 미약한 수준이다.(중략)

2010년 GDP는 전년 상반기 부진의 기저효과로 4.8% 성장이 전망된다. 2010년 민간소비는 경기부양 효과의 감소, 고용 부진, 교역조건 악화로 4.2% 내외의 증가가 예상된다. 2010년 제조업 내수는 상대적으로 높은 증가세를 나타내는 IT산업군이 주도할 전망이다. 생산은 전년대비 기저효과와 수출 및 내수의 회복세에 힘입어 대부분의 업종이 증가세로 돌아서는 가운데, IT산업군이 제조업 생산을 견인할 전망이다. 수출은 원화절상 기조가 제약요인이나, 성장세가 지속되고 있는 중국과 개도국에 대한 수출 호조로 10.8%증가하여 2008년과 비슷한 수준이 될 것으로 전망된다. 2010년 10대 주력업종의 수입은 2009년의 24.0% 감소에 대한 기저효과로 12.4%의 높은 증가율이 전망되나, 규모는 2008년에 못 미치는 수준일 것으로 예상된다. 본 고는 산업연구원에서 발표한 '2010년 경제 산업 전망' 보고서를 요약한 것이다.

본 논문에서는 경유가격에 의한 시장왜곡의 한 측면으로서 우리나라 기업의 물류 투자가 상대적으로 낮게 이루어지고 있음을 지적하고자 한다. 낮은 경유가격으로 상품의 원가는 당분간 낮게 유지될 수 있었을지 모르나 결국 물류투자의 수준을 낮추어 물류설비 수준을 적정이하로 만든 요인이 되며, 이는 다시 물류비용을 증가시키고 결국 원가상승(原價上昇) 요인으로 작용하여 국제경쟁력에 미치는 종합적 효과는 불분명하다고 할 수 있는 것이다. 이러한 문제점은 비단 경유가격에만 한정되는 것이 아니라 산업용 전력요금 등 여타의 경우에도 적용된다. 산업의 경쟁력과 물가안정을 위해서 특정재화의 가격을 낮게 유지하는 것은 결국 가격구조를 왜곡하게 되고 다른 부수적인 문제점을 수반하게 되어 적정수준이 아닌 자원배분(資源配分)을 일으키게 된다. 따라서 산업정책(産業政策)의 일환으로 추진되어온 경유에 대한 가격규제는 보다 합리적인 자원배분(資源配分)을 위하고 장기적인 산업경쟁력(産業競爭力)을 고려하여 신중히 재검토되어야 할 것이다.

This paper is the first part of a research which looks into the regional development process and the quality of life of Youngnam area, and which suggests a prospect and tasks for the future development of the region. Youngnam region has grown rapidly on the basis of labor-intensive light industries and standardized Fordist lage-scale heavy industries through the industrialization and urbanization of South Korea from the 1960s; but recently it has shown a relatively downward trend. The recent economic stagnation of Youngnam region can be seen as a result of uneven regional development in the national scale, which has brought out the increasing subcontracting relation within the region, the geographically excessive concentration of firms, the lack of growth potentiality of high-tech industries, the weakness of producer service, and the shortage of financial activities for capital flows. In addition, construction of physical and social infrastructures and management of urban central functions could not meet properly the rapid economic and urban growth of the region. Because of these problematics inherent in the economy of Yougnam region, the occupational status of regional dwellers is more or less unstable, and the wage level of employee as a whole in Youngnam region is lower than those of Seoul, although the wage level of labourers in manufacturing is relatively high. Moreover, the quality of life of dwellers in the region has some difficulties in the use of resources and ecological environment as well as the unequal provision of means of living and welfare facilities, even though it has been improved materially.

This paper explores micro-contexts of transnational migration and decision-making process of foreign migrants in Korea with four types, that is, married immigrants, immigrant workers, professional immigrants, and foreign students, analyzing dates of questionaries and interviews. Some findings can be summarized as follows. First, married immigrants and immigrant workers show relative lower level of micro-environments than professional immigrants and foreign students. Secondly, immigrants workers fill closest in geographical contiguity among immigrants' types, while married immigrants recognize more different in cultural comparison than the former. Both immigrants workers and foreign students think living environments of Korea better than other types, but immigrants workers consider relatively higher the level of technology, while foreign students evaluate lower that of education in Korea than other types. Thirdly, married immigrants give a relatively low score to the easiness of immigration, while both immigrant workers and professional immigrants give a high score to the job environment of Korea. Finally, all types of immigrants show a high portion in a self-decision making for international migration, while professional immigrants have much more experiences on visiting other countries than other types, and both married immigrants and foreign students seem to have utilized their networks with family members who live abroad.
