本研究以關係人銷貨、關係人進貨、關係人融資、財報重編次數及財務主管異動次數等五項準則,運用VIKOR篩選出關係人交易比率較高且財報重編及財務主管異動次數較多的100家公開發行公司,再以班福法則分析銷貨狀況,結果發現企業營收淨額受人爲操縱之影響顯著。顯示台灣企業以關係人交易調整營收淨額作爲盈餘管理工具之情形日益增多,本文運用VIKOR方法篩選後,較相關文獻單純以班福法則,更容易檢驗出財務報表遭受人爲舞弊之情形。本研究之政策意涵在於提醒政府主管當局應正視台灣整體證券市場以關係人交易及營收淨額作爲盈餘管理工具之情形,以保護投資大眾及債權人之權益。
This study utilizes VIKOR (VIšekriterijumsko KOmpromisno Rangiranje) method and five important financial features to analyze 100 publicly issued companies. Benford's law is applied to examine the relationship between net sales and related party transactions. According to the study results, joint application of VIKOR and Benford's law appears to be more applicable to identify the manipulation of corporate monthly sales than the use of Benford's law alone. VIKOR method, as we suggested in this paper, can therefore be adopted by relevant government agencies and auditors as an effective tool in uncovering financial crises of Taiwan stock market so as to provide more thorough protection to investors and creditors.
