Abstract

This study investigated one of the contemporary issues in the Korean capital market and two hypotheses of concern were tested on the financial determinants of profitability for the firms belonging to the Korean chaebols during the era of the post-global financial turmoil. The first hypothesis applying conditional quantile regression (CQR) estimation provided the evidence that leverage ratio, fixed asset utilization, and foreign ownership among the nine quantitative explanatory variables, had overall statistical significance relative to the book-valued profitability measure, while additional variables such as a firm's size, fixed and a proxy for the type of exchange market showed their strong impacts on the market-valued profitability indicator. Concerning the formulated 'extended' DuPont system, only two components of EBITDAEBIT and EMULTIPLIER revealed their prominent influence on ROE (Return on Equity) over the two tested periods (the years 2008 and 2012).

본 연구는 국내 자본시장에서의 최근 주요 관심이슈 중 하나인 국제금융위기 이후 재벌그룹 소속 계열사들의 수익성 분포 편향가능성과 관련된, 동 지표에 대한 재무적 결정요인의 분석이다. 연구대상으로 공정거래위원회에서 규정한 대규모기업집단과 유사한 의미인 국내 재벌그룹 중심의 소속 계열사들이며 특히, 시장가치 산정을 위하여 유가증권시장과 코스닥시장에 상장된 기업들로만 구성된다. 또한, 동 연구기간은 국제금융위기 이후의 기간인 2009년부터 2012년 사이로 선정되었다. 관련 분석을 위하여 2가지 가설들이 설정되었으며, 전자는 분위회귀모형을 이용한 각 해당 비율 구간별 재벌 계열사들의 수익성 결정요인들을 각각 판명하여 비교분석하는 것이며, 후자는 5가지의 요인들로 구성된 '확장적' 듀퐁공식을 기준으로, 프로빗 모형분석을 이용한 표본기업들의 재무적 차별요인들을 분석하는 것이다. 도출된 결과와 관련하여, 수익성에 대한 재무적 결정요인으로서 부채비율, 비유동자산회전율, 외국인지분율, 그리고 주식거래시장의 구분 등이 통계적인 유의성을 나타냈으며, 두번째 가설검정 결과는 자기자본수익률에 영향을 미치는 요인들로서, 자기자본(시장가치 기준) 대비 매출액 비율과 부채비율 등이 재벌소속 기업들의 금융위기 시점과 최근까지의 변화되는 재무적 특성으로 판명되었다. 또한, 현재 정책적인 측면에서 기업들의 사내유보금에 축소에 대한 논리와 관련하여 본 연구에서는 기업의 유보금과 수익성 증대의 상관관계에서 통계적 비유의성을 보였다.
