본 연구에서는 우리나라 266개 상장기업을 대상으로 기업다각화의 동기를 밝히고, 대리권문제와 기업다각화가 기업가치에 미치는 영향을 분석하였다. 기업다각화수준의 결정에 있어 대리권문제의 영향을 분석한 실증결과에 의하면, 첫째, 내부 지분율이 낮을수록 다각화가 많이 이루어지고, 내부지분율이 높을수록 다각화수준이 낮아지는 것으로 나타나, 우리나라 기업의 다각화 동기를 대리권문제 관점에서 찾을 수 있음을 알 수 있었다. 둘째, 외부대주주지분율과 다각화수준간에는 유의적인 관계를 발견하지 못하여, 외부대주주들이 경영자를 감시 통제함으로써 대리권문제를 축소시키고, 기업의 다각화를 억제할 것이라는 가설은 기각되는 것으로 나타났다. 다각화가 기업가치에 미치는 영향에 대한 분석결과에서는, 첫째, 다각화가 기업가치의 감소를 유발시켜 다각화수준이 높을수록 기업가치가 낮을 것이라는 가설은 기각되는 것으로 나타났다. 오히려 우리나라 기업에 없어 다각화는 기업가치에 긍정적인 영향을 미치는 것으로 분석되었다. 둘째, 관련다각화 기업과 비관련다각화 기업의 가치를 비교해본 결과 비관련다각화 기업의 가치가 관련다각화 기업의 가치보다 높은 것으로 나타났다.

This study purposes to analyze how the level of diversification affects cost stickiness behavior. Specifically, we document that cost stickiness behavior is bigger in case of firm with a high level of related diversification. The purpose mentioned above are empirically tested using 1,508 firm-year data listed on Korea Stock Exchange from 2000 to 2009 and regression analysis methods were used for the analysis of the research hypotheses. The following are the results of this study : First, the increase in SG&A(selling, general and administrative costs) as sales increases is greater than the decrease in SG&A in respect to the equivalent decrease in sales. Second, cost stickiness behavior is bigger in case of firm with a high level of diversification. Also, cost stickiness behavior is bigger as the level of related diversification increase. These results imply that the level of diversification effects on the cost stickiness behavior.

우리나라 재벌기업은 소유집중에 의한 소유경영과 비관련사업다각화를 경영의 특징으로 하고 있으며 정부는 경제력집중의 완화와 재벌기업의 경쟁력 제고를 위하여 공정거래법 등을 통하여 소유분산과 업종전문화를 지속적으로 추진해 왔다. 본 연구는 이러한 정부의 재벌정책에 방향을 제시코자 재벌기업의 기업지배형태를 고찰하고 30대 재벌기업의 1997년 자료를 이용하여 그룹차원과 개별기업차원으로 나누어 재벌기업의 소유구조 결정요인을 실증적으로 분석하였다. 분석 결과 그룹차원에서 소유구조결정요인은 상장비중을 제외하고는 뚜렷한 요인이 식별되지 않아 그룹차원에서는 대주주가 지분관리를 하지 않는 것으로 나타났다. 개별 기업차원에서는, 먼저 대주주의 총지분은 개별기업의 특성과는 거의 무관하게 결정되는 것으로 나타났으나, 개인의 지분은 상장후 경과년수 및 기업규모와 부의 유의적인 관계를 나타내었으며 법인지분은 기업규모와는 무관하나 상장후 경과년수와는 오히려 정의 유의적인 관계를 보였다. 또한 주력기업에 대하여는 대주주가 개인지분을 높게 유지하려는 경향이 있음도 드러났다. 또한 총지분을 종속변수로 사용한 경우의 모형의 설명력이 개인지분이나 법인지분을 종속변수로 사용한 경우에 비해 현저히 낮게 나타나 향후의 소유구조 결정요인에 대한 연구에 있어서 종속변수로서 총지분을 사용하고자 하려면 면밀한 사전분석이 필요함이 시사되었다.

This study analyses the business performance according to the business diversification of Korean mass media enterprises from year 2003 to 2006. The conclusions drawn which could be divided into five main parts are the followings: First, newspaper companies pursue unrelated diversification in various industrial areas, in order to gain maximum profit while broadcasting companies exert themselves to provide better service by diversifying the major contents. Second, overall the interviewed companies display a constant decline in profit gained from their major business area thus establishing strategies to broaden their focus on diversification of any sort. Third, the researcher completed group analysis in regard of diversification measure resulting in division of three groups. The group which had the most immense diversification range gained the highest ROE, the lowest ROE volatility, and lesser probability of risk taking. The analysis adresses the companies broadening their business areas by researching and focusing on diversification are relatively stable in terms of the profit they gain. Fourth, the middle level group in terms of sales scale, debts, enterprise history, major share rate and high ROE group carry out diversification progressively. The sales scale affects positively to diversification, while the major share rate affects negatively to diversification. Fifth, in accordance to the research, diversification overall contributes to obtainance of successful outcome. Since there was not an immense amount of studies to be referred in the media area, the researcher interviewed and did panel discussion with numerous strategists and managers who are in charge of diversification of media companies. However, collection of only 4 years of data limits the research to be considered to be a generalized study, and does not reflect time gap between business diversification and business performance. Development is required in future studies to be established regarding the media companies' specificity different to other industries, classified the media companies into media types, and consider the time gap in the diversification activities and business performance.

The miraculous growth of Korean economy and its business corporations during 1960' s and 1970's are mainly due to the government leadership and its market intervention. We can find the reasons why the government initiated economic growth plan was so successful in Korea in its efficient bureaucratic government system and fair discipline to the corporations based on its contribution to the economy. During 1960's, the primary factors for the growth of business entities and the formation of business groups were the financial special favor, the preferential treatment in the new industry entrance and the merge & acquisition, lavish export incentives from the government, and the export explosion to Vietnam. During 1970's, the substantial deduction of corporations' private debt, enormous support in heavy industry investment, special benefits to general trading companies by the government, and the construction export to the Middle-East were the main causes of the business growth and the business groups formation. Also, the economic rent for the big companies had still been effective since 1960's. However, the preferential benefit to the big companies made them to diversify into the unrelated business ares and to be in very vulnerable financial position. The governmental support brought about the monopoly as well.

The purpose of this study is to analyze the effects of the collective characteristics of SMEs on M&A activity on the disclosure effect of mergers and long-term business performance after mergers. From 2000 to 2012, we examine 717 cases of small and medium-sized enterprises (SMEs) using multiple regression analysis and difference analysis. The results of this study are as follows. First, it is confirmed that the effect on the merger announcement effect is the same as the previous study on the Korean capital market listed companies except for the effect of diversification, listing effect, and cross-border effect. In addition, we have found that firms with higher performance in the past have higher excess returns in the disclosure effect of mergers and acquisitions. Second, unlike the previous studies that non-related mergers have a positive effect on long-term operating performance, for the characteristics of SMEs with lower market competitiveness than that of average listed companies, SMEs merging with same industry group companies have a positive effect on long-term operating performance. This study provides a new perspective on the merger and acquisition of SMEs by examining the effects of M&A announcement and long-term performance.

Data Envelopment Analysis(DEA) is an operations research-based method for measuring the performance efficiency of decision units that are characterized by multiple inputs and outputs. DEA has been applied successfully as a performance evaluation tool in many fields. However, it has not been extensively applied in the shipbuilding industry. This paper applied the input-oriented DEA model, and Malmquist indices to the 7 shipbuilding firms to measure the efficiency and productivity changes during the period of 2004 to 2009. The Malmquist indices will be decomposed into three components such as pure efficiency change, scale efficiency change, and technical change. The empirical results show the following findings. First, the DEA findings indicate that main source of inefficiency is scale rather than pure technical. Second, the Malmquist indices show that an overall decrease in productivity.
