本研究以台灣證券交易所民國87年至89年間上市電子資訊公司為研究對象。探討操作衍生性金融商品與操縱裁決性應計項目，在經理人員欲達到一定水準的損益平穩決策時，兩者是否具部分可替代性。並分析衍生性金融商品之避險操作，其可能原因是否來自於代理問題、財務危機成本、成長性機會、匯率風險暴露程度、企業規模、避險替代工具，亦或是其他原因所致。
實證結果發現經理人員確實會藉由操作衍生性金融商品或是操縱裁決性應計項目來管理盈餘，且兩者呈顯著負相關，也就是在維持損益平穩化的管理決策上，兩者具部分可替代性。另外，研發比率、外銷比率及公司規模與是否使用衍生性金融商品避險之決策，呈顯著正相關，與預期結果相符。而經理人員之酬勞、經理人員之持股比率、短期借款比率及淨營運循環等衡量變數與預期方向相反，其中經理人員之酬勞、經理人員之持股比率未達顯著水準。在衍生性金融商品使用程度上，經理人員之酬勞、負債比率及股利發放等衡量變數有顯著正相關效果，與預期結果相符。而短期借款比率則顯著與預期方向相反。

This research is targeting on the public trading electronic companies listed on the Taiwan Stock Exchange Corporation for the period between 1998 and 2000. It tries to discuss the managers using derivatives and discretionary accruals as partial substitutes for smoothing earnings, and analyze the reasons behind financial instruments hedging whether these hedging activities are resulted from the behaviors of the managements, financial debt, growth option, risk exposure, firm size, dividend policy, liquidity, or the other reasons.
The results find a significant negative association between derivatives’ notion amounts and proxies for magnitude of discretionary accruals. In addition, the R&D ratio, the exporting ratio and the firm size positively correlated with using of the derivative hedging, which is consistent with our prediction. And the bonus of CEO, the stock of CEO, short debt ratio and cash cycle are negatively association with the using hedging activities, which is not consistent with our expectations. However, the proxy for the bonus of CEO and the stock of CEO did not meet the standard of significant negative association. The bonus of CEO, debt-equity ratio and dividend yield positively corre-lated with derivative hedging scale, which is consistent with our prediction. The short debt ratio is significant negative with our prediction.
