In the light of the tremendous impact of global financial crisis, an increasing number of companies will or have already faced financial challenges and hurdles at various levels. It is very likely that senior executives at these companies might conduct the related party transaction behavior under such circumstances. The samples of this research are collected from the Taiwan Economic Journal (TEJ) database for companies listed on TSEC (Taiwan Stock Exchange) or GTSM (Gre Tai Securities Market), dated from 2006 to 2008. The samples have 78 companies including 26 companies with severe financial crisis and 52 companies with healthy financial outlook. This research employs a logistic regression prediction model. In addition to using a traditional financial ratio as a variable to predict the accuracy of such financial crisis, this model also adds related party measures as independent variables. The research result concludes that the accuracy of the model increases by 6.4% after incorporating related party transaction measure into the model.
