運用決策樹建置企業繼續經營假設疑慮之危機預警模型與模型驗證

Development and Validation of a Distress Early Warning Model by Using Decision Tree Base on the Qualified Opinion

指導教授 : 廖咸興

摘要


本研究運用資料探勘決策樹方法,同時考量財務與非財務指標,以會計師已出具繼續經營假設疑慮之保留意見的公司作為研究標的,同時透過權重處理多期的指標變數,建立一套企業危機預警模型,以找出財務危機發生前,企業財務或非財務行為異常模式,真正達到及早預警之效果。 模型研究結果顯示影響企業繼續經營的財務因子包含有股東權益率、利息保障倍數、應收帳款及存貨週轉天數等,以及非財務因子則有董監事質押比、關係人交易等因子。依模型結果危機公司可分為四類,分別為:「高財務槓桿、低利息保障倍數且董監事無心於本業」、「產業衰退、董監事無心於本業之企業虧損高危機風險群」、「企業嚴重虧損且關係人交易異常群」、「高財務槓桿且關係人交易異常具償債危機群」,其中有五成以上的危機公司多屬第一類危機。 模型結果顯示其正確率及正確預測出危機公司的反查率(Recall Rate)均高達九成以上,同時時間內與時間外的資料驗證結果都顯示模型有很好的穩定度,以及沒有過度配適的狀況,因此無須進行模型調整程序。本研究同時以Altman(1968)發展的Z-SCORE模型當作標竿比較,結果顯示本研究模型在各評估指標均有很好的模型表現。

並列摘要


This study utilizes decision tree algorithm, coordinated with financial and non-financial factors, to investigate the companies bearing qualified opinions of going-concern basis issued by CPA. Besides, this study also establishes a corporate distress prediction model by weighting variables of multi-period in order to warn of abnormal patterns of corporate financial or non-financial activities before financial distress happens. Results from this model indicate that financial factors contain quity ratio, Interest coverage multiples, Account receivables and Days in sales of inventory and that non-financial factors contain Board pledge ratio and Related party transaction. According to the results, distress companies can be categorized into for types where more than fifty percent attributes to Type I. Results from this model indicate that the accuracy and recall rate that correctly predicts distress companies are higher than ninety percent. In addition, based on verified results from out-of-sample and out-of-time data, this model possesses great stability without over-fitting phenomenon, showing that model tuning is unnecessary. Moreover, since this study takes Z-SCORE model developed by Altman(1968) as benchmark, excellent performance is obtained for each evaluation indicator.
