摘要: 2003 年 12 月 25 日台灣公佈財務會計準則公報第 34 號「金融商品之會計處理準則」, 34 號公報主要是規範金融商品的衡量與認列,原則上採公平價值評價方式,並對避險會計的適用與處理做更嚴謹的規範,但公平價值之評價方式與嚴格的避險條件規範可能會對企業的避險活動與盈餘波動造成影響。 本研究選擇台灣產值最高的資訊電子業為主,以 2002 年至 2004 年上市上櫃之資訊電子業公司為研究對象,有效樣本911筆,利用獨立樣本 t 檢定、 Probit 迴歸及 Tobit 迴歸等統計方法,探討影響台灣資訊電子業公司其操作衍生性商品避險之顯著因素為何,其操作衍生性金融商品的程度與數量上,是否會受到 34 號公報公佈的影響,以及該產業上市上櫃公司的盈餘波動性或現金流量波動性,在 34 號公報公佈前後,是否有顯著的差異。 本研究所獲得之實證結果如下: 1.影響企業避險與否之重要因素有長期負債比率、外銷比率、公司規模以及內部管理者的持股比例,符合降低投資不足、產業特性以及降低代理問題之避險理論,且 34 號公報公佈後對於企業使用衍生性商品進行避險有顯著影響。 2.衡量 34 號公報之公佈對盈餘波動性的影響結果發現,有避險公司在 34 號公報公佈之後,其公司的盈餘波動性會顯著大於未避險公司之盈餘波動性。 3.2002 年至 2003 年影響台灣資訊電子業使用衍生性金融商品避險程度之顯著因素為公司盈餘之波動性,當公司盈餘波動性較大的公司,其使用衍生性金融商品避險的程度愈高; 2004 年的實證分析結果發現,具有外銷比例愈高、內部管理者的持股比例愈高、公司規模愈大之公司、其使用衍生性金融商品避險的程度就愈大。
