본 연구에서는 국내 주식시장에서 경제적 불확실성이 주식가격 결정에 어떠한 역할을 하는지 살펴보았다. 이를 위해 2000년 1월부터 2017년까지 우리나라의 비금융기업을 대상으로 국내외(미국, 중국)의 경제적 불확실성 지표와 주식수익률의 관련성을 분석하였다. 분석모형은 Fama and French(1992)의 3요인 모형과 모멘텀, 유동성을 포함한 5요인모형을 이용하였다. 분석결과 경제적 불확실성의 베타가 낮은 포트폴리오보다 높은 포트폴리오의 주식수익률이 높게 나타났다. 이는 미국의 분석 결과와도 동일하였다. 또한 한국의 경제적 불확실성 지수를 통한 분석 회귀분석 결과보다 미국의 불확실성 지수를 이용한 분석 결과가 더욱 유의하게 나타났다.

The paper aims to investigate relationships between technology and innovation management, total factor productivity and economic growth in China. By comparing the trends in total factor productivity growth of industrialized economies (i.e. OECD), this study intends to showcase the importance of total factor productivity progress in the Chinese economy. The study employs time series data of an annual basis for the period from 1977 to 2016 retrieved from the World Development Indicator. The study employs unit root test, cointegration test, fully modified least squares estimation method, canonical cointegrating regression and dynamic least squares estimation method to test the hypotheses. The results of the cointegrating regression analysis show that manufacturing growth leads to an increase of total factor productivity in the short-run in China. The findings of the study suggest that manufacturing (i.e. technology and product innovation) is positively related to the increase of total factor productivity in the short-run and total output growth in the long-run. The findings suggest that promoting technology and innovation management and supporting R&D subsidies may reduce the marginal cost of conducting R&D and increase the rate of technology and innovation management and R&D activity and therefore, the total factor productivity growth rate.

Various statistical models to Estimate GDP (measured as a nation's economic situation) have been developed. In this paper an autoregressive distributed lag model, factor model, and a Bayesian VAR model estimate quarterly GDP as a single model; the combined estimates were evaluated to compare a single model. Subsequently, we suggest that some combined models are better than a single model to estimate quarterly GDP.

The purpose of this study is to prove that interchange is the a key factor in costume style changes through case analysis in costume culture interchange, and further, to assist in gaining understanding of costume style changes of the present and the future. Study findings show that the pattern of acceptance of costume interchange was mostly integration, though it was influenced by the method of transmission. The integration is a process in which a foreign costume culture is constructively mixed into the existing one, and a factor that changes the existing costume culture.

본 연구는 서울시민의 삶의 만족도에 관한 연구로서, 삶의 만족도에 대한 고용 형태(창업자/임금근로자)와 사회적(사회자본) 및 심리적 요인(자기효능감)의 상대적인 영향력을 살펴본 연구이다. 서울시복지패널 데이터를 이용한 실증 연구 결과, 심리적 요인의 영향력이 가장 컸으며, 경제적 요인(가계소득 수준), 사회적 요인 순으로 나타났다. 고용 형태 역시 삶의 만족도에 유의한 요인이었는데, 임금근로자가 창업자에 비해 삶의 만족도가 높았고, 임금 근로자의 경우 경제적 요인이외에 자기효능감과 규범, 비공식네트워크 참여도, 비영리기관 신뢰도가 삶의 만족도에 유의한 영향을 미쳤다. 창업자는 경제적 및 심리적 요인과 사회적 요인 중에서 규범만이 유의하였다. 끝으로 연구 결과를 토대로 일자리 창출과 시민들의 삶의 만족도 향상을 지향하는 정책 실무자들을 위한 실천적 시사점을 제시하였다.

The purpose of this study is to examine the effects of residents' perceptions of tourism impact and conflicts on residents' participation in rural tourism village. Method of analysis involves factor analysis and regression analysis in this study. In order to measure the level of perception, three factors(economic benefits, social benefits, social and environmental cost) are derived from the factor analysis. And also in order to measure the level of conflict, two factor(openness of information, leading of operation) are derive from the factor analysis. The result of regression analysis indicate that perceived economic benefits and social benefits are rather greater impacts on residents' participation than social and environmental cost, and also openness of information is rather greater impacts on residents' participation than leading of operation.

In this paper, I analyze the GHG (greenhouse gas) emission factor of the domestic railway transportation sector using the LMDI (Log Mean Divisia Index) methodology. These GHG factors are the emission factor effect, energy intensity effect, transportation intensity effect, and economic activity effect. The analysis period was from 2011 to 2016, and the analysis objects were an intercity railway, wide area railway, and urban railway. The results show that the GHG emission of railway transportation sector decreased during these 6 years. The factors decreasing the GHG emission are the emission factor effect, energy intensity effect, and transportation intensity effect, while the factor increasing the GHG emission is the economic activity effect.

This paper presents the policies Korea adopted to educate and train scientists/researchers and technicians/skilled workers. The Korean policies for the increase of human resources in science and technology that stimulated an upgrading of skills in industry and adapted to technical advancements are identified. An important factor is that the supply and demand mechanism created a virtuous circle so that the science and technology education and training policies were responsive to economic demands. In addition, policies to foster a human resource capacity have enhanced the contribution of human resources in science and technology for innovation and economic growth.

In the case of existence of second-hand market, some methods for economic depreciation measurement have been developed. Among them, we consider two method. Those are Box -Cox model by Halten and Wykoff and Ratio method of T-factor by Iowa State University. Here, we suggest a new measurement method of economic depreciation based on the above two methods. According to the new method, we can get the failure rate of a equipment under the appropriate assumption. Then we can measure the economic depreciation more simply.

This study aims to identify the decision-making factors of people who have returned to rural areas for farming and residence according to personal characteristics and regions. The survey was conducted on 420 return farmers of six cities and counties in Gyeongsangbuk-Do from September 1st to October 11th 2013. For data analysis, researchers used 280 answered sheets and utilized two-way ANOVA and multinomial logistic regression analysis. Research results indicate three factors of returning to farm which are pull to rural area, push from city, and policy factor. The highest scores of factor is pull to rural area (2.93), the second one is push from city (2.31), and the lowest score is politic factor (2.18). In addition, these three factors of returning to farm are elucidated by environmental variable, economic variable, and information and opportunity provided by government. In other words, the factor of pull to rural area is related environmental variable and the factor of push from city is affected by economic variable. Lastly, politic factor pertains to information and opportunity provided by government.
