Abstract

Existing studies have shown consistent results that a diversification discount phenomenon occurs, which means that the value of the company decreases as the degree of diversification of a company increases. Nevertheless, it is explained by the agency theory as a factor that continues to promote diversification by companies. And in order to solve the agency problem, it is important to form an effective governance structure. In order to solve these problems, this study aims to study how the directors' concurrent information affects the monitoring effect of the board of directors through this affects diversification.To this end, research was conducted on KOSPI companies for 6 years from 2011 to 2016.As a result of the analysis, in the case of the concurrent appointment of the CEO and the inside director, there was a positive (+) effect, but the significance could not be confirmed. In the case of adjunct appointments as outside directors, positive results were confirmed that were significant for diversification.

기존의 연구에서 기업의 다각화 정도가 클수록 기업가치가 하락한다는 다각화 할인 현상이 발생한다는 일관된 결과를 제시하고 있다. 그런데도 기업들이 지속해서 다각화를 추진하는 요소로 대리인 이론으로 설명된다. 그리고 대리인 문제를 해소하기 위해서는 효율적인 지배구조를 형성하는 것이 중요하다. 하지만 기존의 연구들은 주로 경영지분율 등을 중심으로 이루어져 왔고 이사회를 구성하는 개인에 대한 고려가 부족하다. 본 연구에서는 이러한 문제점들을 해결하기 위하여 이사들의 겸임 정보를 통하여 이들의 겸임이 이사회의 모니터링 효과에 어떠한 영향을 이를 통해 다각화에 어떠한 영향을 끼치는지 연구하고자 한다. 이를 위하여 2011년부터 2016년까지 6년간 유가증권시장에 기업을 대상으로 연구를 진행하였다. 분석 결과, 경영자와 사내이사 겸임의 경우 양(+)의 영향을 미치기는 하였으나 유의성은 확인할 수 없었다. 사외이사 겸임의 경우 다각화에 유의한 양(+)의 결과를 확인하였다.
