| Summary: | 碩士 === 國立政治大學 === 會計研究所 === 99 === This study investigates the relation among earnings quality, risk factors and cost of equity, especially, the existence of the effect of earnings quality on cost of equity while risk factors are considered, and the impact order of determinants of cost of equity.
Fur measures of earnings quality are examined in the study of determinants of cost equity. We investigate how three individual measures of earnings quality and risk factors affect cost of equity. Then, we use the common factor score of these three individual measures of earnings quality as a composite of earnings quality to examine the impact of earnings quality and risk factors on cost of equity. Furthermore, we standardize variables to order the effects of determinants of cost of equity.
The empirical result shows that both the absolute value of abnormal accruals and the composite factor score of earnings quality have positive effect on cost of equity. With three individual measures of earnings quality and risk factors as determinants of cost of equity, the effects in order the ratio of book value of equity to market value of equity, are the ratio of debt to market value of equity, unsystematic risk, firm size, shares turnover, momentum effect, systematic risk, absolute value of abnormal accruals and the ratio of debt to book value of equity. While with the composite common factor score and risk factors as determinants of cost of equity, the effect in order are the ratio of debt to market value of equity, unsystematic risk, firm size, shares turnover, momentum effect, the ratio of book value of equity to market value of equity, systematic risk, the ratio of debt to book value of equity and common factor. As a conclusion, the earnings quality is statistically a significant determinant of cost of equity after considering a variety of risk factors.
