對於銀行管理當局績效的衡量，除了盈餘表現外，逾放比率與資本適足率高低也是兩項主要的觀察指標。在眾多的盈餘操弄項目中，壞帳提列是唯一可能同時影響銀行盈餘、逾放比率及資本適足率的會計科目。本研究主要目的在於探討銀行管理當局在提高盈餘、降低逾放比率及提升資本適足率的要求下，利用裁決性壞帳提列所為之盈餘管理與銀行壞帳提列前盈餘、逾放比率、資本適足率、資產規模、放款成長率及催收款項之間的關係。
本研究另外依銀行業務屬性，將樣本銀行區分為商業銀行及其他類別銀行兩組；依銀行設立時間為區分標準，分為新銀行與舊銀行兩組；並依銀行董事長是否由官股選派，分為官股掌控銀行及非官股掌控銀行兩組，以了解在不同分類標準下，不同組別的管理當局其利用裁決性壞帳提列所為之盈餘管理，是否有顯著的差異。最後，本研究以年度別為區分，以瞭解銀行管理當局利用裁決性壞帳提列所為之盈餘管理，是否有年度別上的差異。
根據台灣經濟新報社之資料庫，本研究實證結果發現：(1)壞帳提列前盈餘、資產規模、催收款項等三項變數與銀行管理當局利用裁決性壞帳提列所為之盈餘管理有關，且當壞帳提列前盈餘越高、資產規模越大、催收款項越高時，銀行管理當局利用裁決性壞帳提列所為之盈餘管理程度也會越大。(2)無法證實逾放比率、資本適足率、放款成長率與銀行管理當局利用裁決性壞帳提列所為之盈餘管理有關。(3)官股掌控與非官股掌控銀行之管理當局，其利用裁決性壞帳提列所為之盈餘管理，在統計檢定上，具有顯著的差異，其中又以官股掌控銀行，其盈餘管理的程度較大。(4)商業銀行與其他類別銀行之間及新銀行與舊銀行之間，其管理當局利用裁決性壞帳提列所為之盈餘管理，在統計檢定上，並無顯著差異；且年度別之差異對管理當局之裁決性壞帳提列也無顯著影響。

For the evaluation of banks’ performance, non-performing loans ratio and capital adequacy ratio are the two major indicators other than earnings performance. Among the various tools for earnings manipulation, loan loss provisions may be the only one that could affect bank’s earning numbers, non-performing loans ratio and capital adequacy ratio simultaneously. In order to satisfy the need to increase earnings and capital adequacy ratio and to decrease non-performing loans ratio, banks may have motivation to conduct earnings management. The purpose of the study is thus to investigate whether there is a relationship between the earnings management by using the discretionary loan loss provisions and the earnings before loan loss provisions, non-performing loans ratio, capital adequacy ratio, asset size, loan growth rate, and loans uncollected.
In addition, the study divides the sample banks into the following categories: (1) commercial banks versus others, (2) new banks versus old banks (based on the time the bank was founded), and (3) state-run versus non-state-run (based on whether the president of the bank is appointed by the government). The study also intends to examine whether earnings management conducted by the bank’s management is different between the various categories.
Based on the empirical results from the Taiwan Economics Journal (TEJ) database, the study found: (1) the three variables of earnings before loan loss provisions, asset size, and loans uncollected are significantly related to the earnings management by using discretionary loan loss provisions, and the higher the three variables, the higher the degree of earnings management; (2) non-performing loans ratio, capital adequacy ratio, and loan growth rate are not found to be significantly related to the earnings management by using discretionary loan loss provisions; (3) state-run banks have conducted more earnings management than non-state-run banks; and (4) there is no significant result found in other analyses for other categories.
