Abstract

The study investigates one of the long-standing, but still controversial issues in modern finance from the international and domestic perspectives. That is, financial components and differences on corporate profitability are identified and compared under the primary hypotheses. Empirical research settings include the sample data as KOSPI-listed chaebol firms, time reference covering the post-era of the global financial turmoil and two differently defined profitability indices measured by the market- and the book-value bases. A majority of total 7 explanatory variables except firm size and leverage ratio reveal their statistically significant power to explain profitability indices for the chaebol firms in the first hypothesis. The results are generally compatible with those obtained from their counterparts of non-chaebol firms. In the second hypothesis applying multinomial logistic model, the chaebol firms are classified into three groups according to the level of profitability. It is then confirmed that variables to represent the market-valued debt ratio, business risk and growth potential are financially discriminating factors among the three groups. The study may provide a new vision to identify financial factors of corporate profitability for Korean chaebol firms after the global financial crisis, which can enhance the benefits of interested parties at the government or corporate level in a virtuous cycle.

본 논문에서는 경영학 재무 분야에서 국내외적으로 지속적인 관심의 대상이지만, 학문적 의견 일치를 보이지 못하고 있는 주제가 연구되었다. 즉, 기업의 수익성에 대한 재무적 결정요인과 상호 차별성이 가설검정을 통하여 상호 비교되었다. 연구 분석 방법과 관련하여 본 연구에서는 국내 재벌 계열사들을 대상으로 표본기간은 국제금융위기 이후의 기간으로 설정되었으며 시장가치와 장부가치 기준의 두 분류의 수익성 지표들이 각각 분석되었다. 첫 번째 가설검정 결과 관련, 총 7개의 설명변수들 중, 기업 규모와 부채비율을 제외한 나머지 변수들이 재벌기업들의 수익성 결정에 유의성 있는 영향을 줄 수 있는 재무적 요인들이었으며, 동 결과는 비교그룹인 비재벌 소속 기업들에 대한 검정 결과와도 일반적으로 유사하였다. 또한, 다항로지스틱 모형을 활용한 두 번째 가설 검정에서는, 표본기업인 재벌기업들이 수익성 수준을 기준으로 3단계로 분류되었다. 이를 기준으로 부채비율, 부도위험성 그리고 잠재성장성을 나타내는 변수들이 재벌기업들 간의 차별성을 나타내는 변수들로서 판명되었다. 본 연구의 결과들은 국제금융위기라는 재무적 시점을 경험한 국내 재벌기업들의 수익성 결정요인들을 판명하는 측면에 새로운 방향을 제시할 수 있다고 판단하며, 또한 선순환적 관점에서 정부와 기업을 포함한 이해관계자들의 향후 이익 제고에도 기여할 수 있다고 판단된다.
