本研究主要之目的在於探討執行電腦審計對於審計品質之影響性,瞭解實施電腦審計是否可以遏止企業對於盈餘管理的動機。本研究以異常應計數作為衡量審計品質之代理變數,並將電腦審計依特性區分為下列四類,1.一般資訊環境控制、2.應用系統資料驗證測試、3.應用系統自動控制測試、4.日記簿風險分錄測試,探討執行各電腦審計項目對於審計品質之影響。 本研究實證結果發現,針對企業資訊系統實施一般資訊環境控制對於提升審計品質有正面影響;而執行應用系統自動控制測試、應用系統資料驗證測試及日記簿風險分錄測試對於提升審計品質則並無幫助。
The main purpose of this study is to investigate the relationship between computer auditing and audit quality, understanding whether the implementation of computer audit can reduce the enterprise motivation for earnings management. In this study, we use the absolute value of abnormal accruals as a proxy for audit quality, and computer audit is divided into the following four categories, 1. General Information Technology Control, 2. Application data validation test, 3. Application control, 4. Journal Entry Testing. This study aimed to investigate the relationships between computer auditing and audit quality. The empirical results of this study found that for the implementation of General Information Technology Control have a positive impact on audit quality, but the implementation of Application data validation test, Application control and Journal Entry Testing for enhancing audit quality is unhelpful.
