本文以2013年台灣上市櫃公司強制導入國際會計準則(International Financial Reporting Standards, IFRS)為研究事件，分別從信評面、風險面與市場面分析此一系統性變化對企業之影響。以期對會計準則影響企業風險提供實證上的證據。
信評面實證結果顯示，強制導入IFRS確實可以顯著增加企業之信用評等分數。惟其解釋力過低，而加入財務與非財務控制變數後又導致主變數有變號之問題，顯示信評面模型相當不穩定。無法斷定其是否支持本文假說。
破產風險面實證結果顯示，強制導入IFRS將顯著地減少企業之破產風險。此實證結果可以表現出，縱使台灣證券市場以自然人居多之投資人結構與西方法人為主之結構不同，但面對因會計準則改變而帶來之財報環境變遷，皆抱持正向看法。
市場面實證結果顯示，強制導入IFRS可以顯著增加企業之Tobin Q分數。代表台灣市場的投資人在評價公司價值時，除了公司本身資產外，亦會考量財報報導環境變動對公司之影響，例如會計原則之變動。

The financial reporting environment changed significantly in 2013 for thousands of public companies when Taiwan mandated the adoption of International Financial Reporting Standards (IFRS). This event provides a natural setting for testing whether changes in the financial reporting environment affect firm-level crash risk. We separate crash risk to credit risk, Tobin Q score and extreme negative stock returns in order to capture the influences completely.
In the empirical result of credit risk, we find a decrease in credit risk and increase credit rating scores among nonfinancial firms after IFRS adoption. Because the model is not stable, we can’t conclude that the result supports our hypothesis 1. In the empirical result of crash risk, we find a decrease in crash risk associated with mandatory IFRS adoption among nonfinancial firms. The result is consistent with prior IFRS studies and supports our hypothesis 2. In the empirical result of Tobin Q score, we find an increase in Tobin Q scores among nonfinancial firms after IFRS adoption. The result supports our hypothesis 3.
