本研究探討IFRS 9實施後是否影響財務報表之價值攸關性。將研究期間區分為IFRS 9實施前 (2015年至2016年) 與實施後(2018年至2019年)兩段期間。參考Ohlson (1995)之模型設計，本研究也分別從綜合損益表及資產負債表觀點區分為受IFRS 9影響大、小組。實證結果發現，除了整體之價值攸關性顯著上升外，綜合損益表減損損失之價值攸關性也呈現上升之現象，亦即減損方法及FVOCI減損報導分類之改變，將影響相關項目之價值攸關性程度，且投資人能瞭解減損損失已不同於IAS 39之資訊內涵。整體而言，IFRS 9公報對減損報導分類之改變，提升綜合損益表金融工具相關科目之價值攸關性。

This study explores whether the implementation of IFRS 9 affects the value of financial statements.The study period is divided into two periods before IFRS 9 implementation (2015 to 2016) and after implementation (2018 to 2019).Referring to the model design of Ohlson (1995), this study is also divided into large groups and groups that are affected by IFRS 9 from the perspective of the consolidated income statement and balance sheet.The empirical results found that in addition to the significant increase in overall value relevance, the value relevance of the impairment loss of the comprehensive income statement also showed an increase. That is, changes in the impairment method and FVOCI impairment report classification will affect the value of related projects. Relevant degree, and investors can understand that the impairment loss is different from the information content of IAS 39.
Overall, the change in the classification of impairment reports in the IFRS 9 bulletin enhances the value of the relevant items of financial instruments in the consolidated income statement.
