We designed this study for verifying the differences of causes and individual results of job stress between Koreans in Korea and Chinese in China of a same company. The results in the study are as follow. Significant differences between two groups were identified in job stressors: Koreans showed higher levels than Chinese for factors like inter-group conflicts, supervision/evaluation, job overload, task characteristics, socio-demographic factors, and Chinese showed higher levels than Koreans for factors like job conflicts, job ambiguity, family-related factors. We also identified that levels of stress perceived by individuals as anxiety, depression, and physical symptoms of Koreans are higher than those of Chinese. As to the influence of job stressors on stress level, Koreans show significant results for supervision/evaluation, decision making/responsibility, family-related factors, and Chinese show significant results for family-related factors, social support, socio-demographic factors. Based on the results of this study, implications, limitations, and future research topics were discussed.

The purpose of this research can be said as follows. The close examination of competitive advantages of Korean enterprises who have been participating and dominating the management activities directly in India. And the Analysing of the correlation between the competitive advantages and the management performances of Korean firms there. That is, the factors which exercise their influence over the local management positively can be activated and developed reasonably and systematically while the others which exercise their influence over it negatively have to be eliminated, at least. The factors of competitive advantages on this paper are from ones which could generally be recognized on the basis of the preceding studies, and the management performances are divided by three sub-variables like sales, profits and management satisfaction. As empirically statistical method, Regression coefficient analysis as inferential statistics as well as Pearson's correlation as descriptive is implemented for this paper of testing some hypotheses.

Information security is an essential element not only to ensure the operation of the company and trust with customers but also to mitigate uncertain damage by preventing information data breach. Therefore, It is important to select appropriate information security countermeasures and determine the appropriate level of investment. This study presents a decision support model for the appropriate investment amount for each countermeasure as well as an optimal portfolio of information countermeasures within a limited budget. We analyze statistics on the types of information security breach by industry and derive an optimal portfolio of information security countermeasures by using genetic algorithms. The results of this study suggest guidelines for investing in information security countermeasures in various industries and help to support objective information security investment decisions.

The cognition for corporate social responsibility of Chinese companies is negative because it increases cost and causes reduction of profit. But interest and execution for corporate social responsibility of Chinese firms is increasing consistently. Purpose of this study is to find effect of corporate social responsibility on firm value to Chinese enterprises. To achieve this purpose, we performed multiple regression method to 647 firms listed on the Shanghai Stock Exchange of China in 2011. Dependent variable is firm value and independent variable is degree of execution of corporate social responsibility to stakeholders. Conclusions of this study are as follows. First, execution of corporate social responsibility for employees, bondholders, government appeared to have a significant positive effect to firm value at 1% significance level. Second, execution of corporate social responsibility for customers appeared to have a significant negative effect to firm value at 1% significance level. Third, execution of corporate social responsibility for stockholders, suppliers appeared to have a weak positive effect on firm value, however these variables showed statistical insignificant.

본 연구는 시장에 정보가 별로 알려져 있지 않은 증권이 많이 알려져 있는 증권보다 높은 추정위험 때문에 더 높은 수익률을 제공한다는 이론적 모형들이 시사하는 바에 기초하여, 수익률이 각 증권에 대해 시장에 알려져 있는 정보량과 역의 관계에 있다는 가설을 세우고 이를 실증분석하였다. 본 연구는 또한 기업규모가 정보량과 정의 상관관계가 있다는 점에서 기업규모보다 정확한 정보량 변수가 포함되면 기업규모효과는 사라질 것이라는 가설도 검증하였다. 미국의 상장주식들을 대상으로 횡단면 실증분석을 실행한 결과, 정보량이 평균수익률의 횡단면을 설명하는 것으로 나타난다. 정보량은 기업규모 변수가 동시에 포함될 경우에는 설명력이 떨어지지만 1월에는 기업규모효과와는 별도로 기대수익률을 설명하는 것으로 나타난다. 한편 기업규모의 변화 또는 기관투자자 지분율의 변화시 수익률이 변하는지에 대한 F-검정을 실시한 경우에도, 정보량은 1월중에는 기업규모 효과와는 달리 통계적으로 유의한 수익률 차이를 보이고 있다. 이와 같은 실증결과들은 정보량 효과가 어느 정도 존재함을 의미한다. 이와 같은 결론은 기존의 CAPM 관련 실증연구들이 주장하는 ${\beta}$의 무용성에 대한 논쟁은 아직 끝나지 않았음을 시사한다. 즉, 각 증권에 대한 모든 정보가 시장에 완전히 알려지지 않은 현실하에서는 추정위험을 감안한 ${\beta}$를 이용하여야만 CAPM을 검증할 수 있는 것이다.

This study explores the determinants of capital structure of the hospitality industry such as hotels, lodging industry and tourism industry using financial data from 2000 to 2019. Several explanatory variables suggested by related theories and past studies were regressed with the dependent variable, debt ratio for the entire sample period, pre-crisis period and post-crisis period and the regression coefficients of the sales expenses, profitability and firm size were found to be statistically significantly negative. Especially the sign of the coefficient of the firm size was opposite to that of the manufacturing industry, which implies the uniqueness of the hospitality industry.

외국인투자 유치를 통해 국내산업의 생산성을 향상시키는 것이 중요한데 외국인투자가 한국의 산업생산성에 어떤 영향을 미쳤는지에 대한 실증연구가 전무한 것이 현실이다. 본 연구는 기업데이터를 이용하여 외국인투자의 생산성효과를 추정하는 것을 목적으로 한다. 상기 분석을 통해 얻은 결과를 요약하면 다음과 같다. 첫째, 외국인소유기업의 노동생산성이 높다. 둘째, 외국인투자의 생산성 파급효과는 양(+)의 효과를 가지나 통계적으로 유의하지 않다. 즉, 생산성 파급효과가 미미하다고 볼 수 있다. 이상의 결론은 매우 중요한 시사점을 갖는다. 우선 외국인투자기업이 선진기술 및 경영노하우를 전수할 능력을 가졌을 가능성을 시사한다. 외국인투자를 유치하는 중요한 이유 중의 하나인 선진기술 및 경영노하우 전수의 전제조건인 외국인투자기업의 기술 및 노하우 소유가 실제로 성립할 가능성을 시사한다. 하지만 외국인투자가 국내산업 전반의 효율성 제고로 이어지는 데는 아직 장애요인이 존재함을 암시한다. 경쟁규율이 확립되지 않았거나 기술파급을 위한 제도적 여건이 미비한 것이 원인일 가능성이 있다. 따라서 정책적인 시사점은 어떻게 기술파급효과를 극대화할 것인가에 집중된다. 경쟁에서 낙오한 기업의 퇴출을 확실히 제도화함으로써 외국인투자의 경쟁압력이 기업의 효율성 증가로 이어지도록 해야 할 필요가 있으며 각종 반경쟁적 관행 또는 행위를 단속할 수 있는 경쟁정책의 확립이 요구된다. 또한 노동시장의 유연성 제고, 산업입지정책의 효율화 등을 통해 외국인투자의 기술이전 및 확산효과가 극대화되도록 해야 할 것이다.

This study analyzed the effect of CSR activities on SME's depending on the degree of risk perception of business environment. We first classify the analysis target SEM's into two groups according to the degree of risk perception, and to examine whether there is any difference in the effect of CSR activities through latent mean analysis. Findings revealed that at First, CSR activities has a significantly positive effect on the improvement of management performance. Also, risk perceptions motives affect positively on CSR activities, the high risk perceptions group was noted to be strongly the effect of CSR activities.
