近期永豐金弊案連續爆發，一連串弊案皆與關係人交易有關，同時在企業財務報表中之文字揭露內容亦因許多文獻皆說明文字是一項具資訊內涵之資訊，加之隨著科技技術的演進，文字探勘的技術亦日趨成熟且日漸備受重視，因此本研究以文字探勘之技術蒐集我國102年至106年銀行業財報中關係人交易性質之資料，並與同為舞弊紅旗之可能因素-盈餘管理做關聯性測試，實證結果發現我國銀行業較會在有進行高層指示關係人交易時，進行較向下且較大幅度之盈餘管理，另經將銀行業做類別區分後，研究結果也發現家族銀行亦較會在有進行高層指示關係人交易時，進行較向下且較大幅度之盈餘管理，其中較特別的是，在其餘銀行類別從事高層指示姻血親交易時幾乎與盈餘管理無顯著關聯，而家族銀行則是會在有從事高層指示姻血親交易時，較會進行大幅度的盈餘管理。;The recent Bank Sinopac fraud case occurred in succession.
