本文利用統計科學方法建構企業信用風險模型(Credit Risk Models)，考慮企業自有資金(Own Funds)情形，找出影響公司績效之顯著變數。期能提供投資人、利害關係人(Stakeholders)及金融機構授信審核，事前預測可能發生財務風險(Financial Risk)之機率，降低財務風險損失(Financial Risk Loss)，進而降低銀行授信之風險性資產(Risky Assets)，提高銀行資本適足率(BIS Capital Adequacy Ratio)，達到事前預警與風險管理之效。實證分析上，利用K-S test，M-U test，針對上市股公司自有資金比率＜50%，建立企業信用風險模型。
實證結果顯示，台灣上市股公司信用風險發生前一年、前二年與前三年之預測準確率，會計資訊變數模型一較複迴歸模型二高，值得投資決策參考。實證結果發現，會計資訊變數影響公司績效之主要指標有財務結構、償債能力、經營能力、獲利能力與現金流量指標；降低借款依存度、增加現金流量允當比率，可提高公司現金流量與經營能力，降低信用風險發生機率；降低負債比率、提高應收帳款週轉率，改善財務結構與公司經營能力。因此，本文之實證價值與管理涵義為，企業建立有效之信用風險模型，可降低信用風險發生的可能性，以為投資融資決策與財務預測之用，進一步可降低銀行授信之風險性資產，提高銀行資本適足率。

This paper primarily used statistical methods to establish logistic credit risk models, discussed the own funds and picked out the significant variables as key indicators of corporate performance. Provide investors, stakeholders and banking make loans, that made it be possible to predict in advance the probability of listings in Taiwan experiencing financial risk, reducing financial risk loss and risky assets in banking make loans, enhancing BIS capital adequacy ratio. In the empirical analysis, when corporate own funds ＜50%, we built up a logistic credit risk model using K-S test, M-U test. Finding, the forecast accuracy rate were the accounting data model I superior the multiple regression model II. The key performance indicators were the financial structure, the solvency, the operating performance, the profitability, and the cash flow. Empirical results suggested that reducing debt/equity ratio, increasing cash flow adequacy ratio could enhance corporate cash flow, operating performance and reduce credit risk. Reducing debt ratio and enhancing receivables turnover, could improve the financial structure and the operating performance. Implications, a major part of the business of financial institutions must follow to minimize credit risk and make successful loans could reduce risky asset and enhance BIS ratio.
