為因應全球化時代之來臨，直接採用國際會計準則 (IFRS)已成為國際資本市場之趨勢，我國財務會計準則委員會自1999年開始進行修改及新訂會計準則，採「趨同方式」與IFRS接軌，至2008年金管會決議改以「直接採用」方式與IFRS接軌。本文將以這兩年作為分水嶺，以長期觀點探討逐步採用IFRS後，三段期間 (1990-1998、1999-2007、2008-2010)內財務報表穩健類型(條件、非條件)及價值攸關性之變化趨勢，接著再進一步探討公司穩健原則之採用是否會影響價值攸關性。

本文研究成果共有四項：(1) 在逐步採用IFRS之情況下，我國上市櫃公司財務報表之條件穩健程度依舊持續上升；(2) 在逐步採用IFRS之情況下，我國上市櫃公司財務報表之非條件穩健程度會由下降轉為上升；(3)在逐步採用IFRS之情況下，我國上市櫃公司財務報表之價值攸關性會有所提升；(4)在逐步採用IFRS之情況下，我國上市櫃公司條件及非條件穩健程度之變化皆不會影響價值攸關性之趨勢。

因此本文實證結果可從三大面向提出整合性實證意涵：(1)報表在逐漸轉換的過程中，顯示並未因為會計準則的轉換，造成穩健程度之下降，因此對於報表使用者而言，並不用擔心與管理者之間產生代理問題。(2)進一步驗證了IFRS對於公允價值觀念之運用，確實提升了報表之價值攸關性，更能表達企業之真實價值，對於報表使用者而言，更有利於其進行投資決策。(3) 在報表轉換期間，公司穩健原則政策之採用並不會降低財務報表之價值攸關性，對於公司及報表使用者而言，既可以維持報表之穩健性亦不會降低價值攸關性，於未來資本市場上，IFRS對於我國之影響將更為有利。

In response to the advent of the era of globalization, adopting the International Accounting Reporting Standards (IFRS) has become the trend in the international capital markets. In 1999, Financial Accounting Standards Board (FASB) had modified the new accounting standards to “converge” the IFRS. In 2008, the Financial Supervisory Commission claimed the new accounting standards change, which “adopt” the IFRS. This study will employ the long-term observation to explore the gradual adoption of IFRS. Moreover, this study intends to discuss whether the adoption of IFRS will affect the trend of accounting conservatism and value relevance in the three periods (1990-1998, 1999-2007, and 2008-2010). Finally, this study will further explore the impact of accounting conservatism on value relevance.

There are four empirical results indicated as follow: (1) Over the three periods, conditional conservatism in Taiwan still remains increasing. (2) Over the three periods, unconditional conservatism in Taiwan changes from dropping to rising. (3) Over the three periods, the value relevance of financial statement has enhanced. (4) Over the three periods, the value relevance of financial statement is not affected by conditional and unconditional conservatism.

The results have three proposed integrated empirical implications: (1) Accounting conservatism is not declined in the past three periods, so investors don’t have to worry about the agency problems between investors and managers. (2) The employment of IFRS enhances the value relevance of the financial statements, and thus expressing the real value of the enterprise and assisting financial statements users to make investment decisions. (3) During the conversion periods, conservative policies of companies did not reduce the value relevance of financial statements. All in all, the impact of IFRS will be more favorable in our future capital market.
