有顯著降低外匯曝險的能力,因此我們得到以下結論:大部分的外匯曝險雖然不 易被察覺,但公司管理階層是否有動機去降低不利的外匯曝險對公司評價所帶來 的傷害仍有機可循,總的來說,公司會研判貨幣走勢,利用可得的衍生性金融商 品進行外匯避險,並且,依公司體質不同或管理者所考慮的重點不同而實行不同 的盈餘管理政策,以期進一步降低外匯曝險、降低投資人對未來公司可能遭遇外 匯風險變動的不安,進而領導股價的走勢。

第二節 研究建議

本研究欲探討外匯波動對跨國企業之公司價值的影響,而選取的標的雖為暴 露於較高的外匯風險的半導體產業,但仍不足以全面性地解釋各種跨國產業面臨 外匯波動的曝險,甚者,本研究因基於各家公司財報揭露程度的差異,無法取得 銷售地區及營收款項的計價貨幣等細部資訊,因此僅能大致將銷售地點區分成四 大洲、營收幣別區分為四大貨幣,在未來衍伸的研究上,建議應尋找一些更普遍 能衡量不同產業外匯曝險的指標,以期能夠更準確地評估出各公司或產業所承受 的匯率曝險。

而在衡量公司所承受之外匯曝險的大小時,本研究僅考慮出口地區、幣別等 因素,但卻未將材料、機器設備等的進口國家、應付帳款的幣別列入考慮,因此 事實上,本研究僅考慮了純粹從出口商的角度來看的外匯曝險,而在實務上,跨 國公司的進出口貿易牽涉的問題往往複雜許多,在未來的研究上,或許可以朝這 方面進行。

最後在實證模型中,盈餘管理因子對公司外匯曝險影響的程度方面,回歸顯 示的反應係數結果雖為負號符合預期,但顯著程度仍不明顯,或許是本研究所依 據的 Leuz et al.(2003)之三種盈餘管理模式在樣本公司檢驗上並不適當,又或 者是盈餘管理並沒有一定的衡量標準,換句話說,公司依標準合法的程序進行財

報的干預時,其背後的目的並不單單僅是為了使公司的外匯曝險下降,在會計科 目的遞延以及公告財會數字的背後,或許是為了別種目的而進行的盈餘管理,針 對此一部分,或許需要向公司進行質化的訪問並配合長期的觀察,才有辦法真正 了解公司進行盈餘管理的真實目的。
