標題: | 自結損益之規範:資訊揭露行為、市場效應與自結盈餘資訊品質 | 作者: | 林嬋娟 | 關鍵字: | 自結盈餘準確度;自結損益制度;盈餘資訊品質;Mandatory preliminary earnings announcement;earnings quality;accuracy of preliminary earnings | 公開日期: | 2003 | 出版社: | 臺北市:國立臺灣大學會計學系暨研究所 | 摘要: | 本研究旨在探討強制自結盈餘的資訊 品質。探討的問題主要有三個:首先,瞭解 強制自結盈餘是否存在樂觀高估的情況;其 次,探究強制自結盈餘準確度的影響因素; 最後,分析自結損益制度的實施效果。 本研究以公開民國90 、91 年度財務預 測,且依規定強制公告自結盈餘的公司為研 究對象。此外,分析自結損益制度的實施效 果時,乃根據選樣標準,並要求同一公司在 自結損益制度實施前(民國86-89 年)後都 至少要有一次自結盈餘揭露。本研究採單變 量t 檢定以及多變量迴歸分析進行實證測試。單變量t 檢定結果顯示,強制自結盈餘 誤差(查核損益-自結損益)顯著小於零, 表示存在系統性高估的現象。多變量迴歸分 析結果顯示,顯著影響強制自結盈餘準確度 的因素有好壞消息(負相關)、股權結構(負 相關)、產業因素(若為營建業,正相關), 此外,公司高估強制自結盈餘,也會使得強 制自結盈餘絕對誤差較大。而自結損益制度 實施後,公司的強制自結盈餘準確度,並未 比制度實施前的自願自結盈餘準確度提高。 The main purpose of this research is to investigate the information quality of preliminary (un-audited) earnings. The research questions are as follows: (1) Is the mandatory preliminary earnings announcement (hereafter MPEA ) optimistically reported? (2) What are the determinants of the accuracy of MPEA? (3) What is the effect of MPEA disclosure regulation on the accuracy of preliminary earnings estimates. Research sample for question (1) and (2) contains the companies required to disclosure MPEA for any year of 2001 or 2002. Research sample for question (3) contains the above companies and the voluntary un-audited earnings disclosure for any year from 1997 to 2000. Both univariate tests and multiple OLS regression analyses are used to examine the relationship between accuracy of MPEA and its determinants. The univariate results indicate that the companies, on average, tend to release optimistic MPEA. After controlling for other factors, we find that the MPEA is more accurate for firms with good news or more insider shareholdings. The accuracy of preliminary earnings estimate is not affected by MPEA disclosure regulation significantly. |
