摘要

本研究對金控子銀行與獨立銀行進行盈餘管理相關之研究。其中採用McNichols & Wilson(1988)提出之壞帳估計模型及Beatty et al.(2002)在探討美國公開發行銀行與非公開發行銀行盈餘管理之差異時,曾提出證券買賣損益之估計式,在計算出可裁決性數額,進行t檢定以及複迴歸分析,得到以下結論：
一、金融控股公司法實施前後,金控子銀行在利用可裁決性壞帳與證券買賣損益有顯著之差異,獨立銀行僅在證券買賣損益有顯著之差異。
二、金融控股公司法實施後,金控子銀行與獨立銀行之壞帳費用及證券買賣損益皆呈顯著關係,金控子銀行之平均數皆大於獨立銀行,由此可知金控子銀行壞帳費用及證券買賣損益調控盈餘程度大於獨立銀行。
三、獨立銀行為了要維持投資人及存款人的信心,利用壞帳費用以使盈餘極大化,金控子銀行為了要證明本身的團隊經營實力或母公司的經營目標,以達到二次金改市占率達10%以上之目標,壞帳費用及證券買賣損益來使盈餘極大化。
四、金控子銀行與獨立銀行,皆會利用增加放款,提升利息收入來平穩其盈餘,並會企圖修飾逾放比,使盈餘極大化。

This study analyzes the difference in earnings management of the subsidiary banks of the financial holding companies and independent banks. The McNichols & Wilson (1988)’s estimating bad debts model and Beatty et al. (2000)’s estimating benefits of the disposal of securities model are used. After the discretionary amount being calculated, this work uses t-test and regression analysis. The results are summarized as follows:
1. This study finds that there is a significant difference in discretionary bad debts and the gains and the losses of the disposal of securities for financial holding companies before and after the implement of the Financial Holding Company Act. However, there is a significant difference exists in gains and losses of the disposal of securities for the independent banks.
2. After the implement of Financial Holding Company Act, the average bad debts and the gains and losses of the disposal of securities of the subsidiary banks of the financial holding companies are greater than independent banks, suggesting that the financial holding company’s subsidiary banks manipulate their earnings level greater than the independent banks do.
3. The independent banks attempt to maintain or improve the confidence of the investors and depositors by utilizing bad debt to maximize their earnings. However, the subsidiary banks of the financial holding companies attempted to demonstrate their team spirits to achieve the objectives of the parent company, whose market share will reach 10% of the market. They employed their bad debts and the gains and losses of the disposal of securities to maximize their earnings.
4. The findings indicate that both the subsidiary banks of the financial holding companies and the independent banks would increase loans to raise interest revenue and stabilize their earnings. Moreover, these two kinds of banks also maximize their earnings by decorating their overdue loan ratios.
