本研究主要探討資訊透明度與台灣銀行業特殊盈餘管理行為之關係，樣本期間為2001年至2004年，探討資訊揭露程度越高情況下，投資人與經理人間資訊不對稱程度降低後，是否會降低銀行經理人操縱盈餘的可能性。
相較於一般產業，銀行業盈餘管理之行為有其特殊性，為了衡量銀行業盈餘管理之行為，本研究採用呆帳費用估計式，計算各期之裁決性呆帳費用(DLLP)，盈餘管理程度的估計，樣本期間涵蓋1996年至2007年，本研究發現銀行經理人有透過銀行業特有之裁決性科目─呆帳費用的提列進行盈餘管理行為的傾向。因此，本研究以複迴歸分析探討資訊透明度與盈餘管理行為之關係，由於銀行可能因資本管制、盈餘平穩化以及規模影響其從事盈餘管理行為之情形，故於迴歸模型中加入期初資本適足率、資產報酬率波動度以及總資產取對數值作為控制變數進行檢測。
根據實證結果發現，資訊揭露的程度與盈餘管理行為呈顯著負相關，代表銀行所揭露之資訊，若屬於能幫助投資人瞭解公司內部組織、風險管理施行狀況以及財務資訊之透明度，則能降低管理階層透過裁決性應計項目從事盈餘操縱之機會。

A number of recent policy initiatives have called for enhanced transparency of banking industry, such as Pillar 3 of New Basel Accord requiring the bank’s more disclosure of financial information in year of 2001. Concurrently, all listed financial institutions in Taiwan were required to disclosure the important financial information quarterly in the network, including asset quality, management information, profitability, and market risk sensitivity except for the financial statements. In this paper, we try to investigate the relationship between financial reporting transparency and earnings management in Taiwan’s banking industry for the period 2001 through 2004. This study will examine whether and to what extent banks in Taiwan use loan loss provisions (LLPs) for earnings management. We hypothesize that the extent of earnings management is negatively related to information transparency. Following Poshakwale and Courtis (2005), we develop a disclosure index to measure the extent of each sample bank’s information transparency. Our results indicate that banks in Taiwan use LLPs to manage earnings. Furthermore, our findings are consistent with the prediction that the highly degree of bank disclosure will reduce the extent of earnings management.
