資本市場對盈餘品質的影響：來自臺灣的證據

How the Capital Market Affects Earnings Quality: Evidence from Taiwan

資本市場的存在究竟是正面提高盈餘品質的助力還是負面降低盈餘品質的壓力，近年來已經成為重要的會計研究議題。我們發現，在經過控制公司規模後，臺灣的上市/櫃公司在盈餘穩健性、避免負盈餘以及損益平穩化等方面的盈餘品質均顯著優於一般公開發行公司的盈餘品質。具體而言，我們的研究發現支持財務報表的需求對盈餘品質有具體影響的觀點。 Responding to the recent debates on how the functioning of capital markets affects earnings quality, this study compares the earnings quality of Taiwan listed firms to that of unlisted public firms. We investigate earnings quality in the following aspects: earnings conservatism, the likelihood of avoiding negative earrings, and income smoothness. The results show that, after controlling for firm size, the earnings quality of listed firms is consistently better than that of unlisted public firms. These findings are consistent with the proposition that the capital market plays a constructive role in enhancing earning quality.
