指導教授 : 蔡政言

摘要


由於各國的國際金融的自由化、國際化、資訊科技日益改善與日趨進步,再加上日趨複雜性的金融商品創新之下,國際資金得以在國際市場之間快速的流竄,同時也使得各國的匯率以及不確定性的波動也是與日倍增。 中央銀行在進行外匯市場干預,主要也是為了影響本國貨幣匯率,並防止匯率在短期內的過度波動而導致在中長期的失調而影響國內經濟,特別是因為特殊狀況的發生將引發市場恐慌。伴隨著總體經濟規則的潛在規則之下,倘若市場恐慌訊息的釋出參雜著各參與者的猜疑與不確定,高逐利性的國際投機性資本也可能因為市場恐慌訊息而迅速抽離市場並造成外匯動盪。 本文採用競合策略PARTS分析,在總體經濟環境規則的限制之下,定位出各個市場參與者以及其附加價值。並以各個市場參與者的角度各別分析,在面對外匯市場動盪之下利用其各自的戰術得以因應時勢而能夠創造對己有利的優勢策略。 透由本文研究結果可以發現,附加價值的絕對優勢,決定了整個賽局關鍵。例如市場參與者中,中央銀行握有直接介入外匯市場的權利、金融機構利用資訊不對稱的優勢等等,將決定其在賽局當中的關鍵影響力。此外,各市場參與者在做戰略考量的同時,又必須跟隨著總體經濟環境的規則而應變,其所決定的策略必須相當謹慎,因為這不單單只牽動國內市場參與者,更有可能影響到其他國家市場參與者的利害關係。 最後,根據本文研究結論得知原先競合策略的價值網隨著市場與賽局規模的逐漸擴增,由單純的價值網,延伸成為多連結性的價值網。為此由原先價值網而提出修正成「連續型價值網」以更符合實際的市場狀況。
