    Abstract: 本研究探討自亞洲金融風暴以來美元指數及黃金現貨價格二者之相關性。樣本期間為1997年7月1日至2009年7月31日之倫敦黃金定盤價午盤價及美元指數收盤價日資料。本文利用EGARCH模型分析兩種金融資產間之關連性,並探討黃金現貨與美元指數收盤價之領先落後關係,最後分析兩者間之波動外溢效果及黃金現貨市場與美元指數間之傳遞效果。實證結果整理於下:
    1.藉由共整合分析,黃金現貨價格與美元指數收盤價間存在有長期均衡關係。
    2.以黃金現貨為被解釋變數時,美元指數有領先現貨的現象,反之,若以美元指數為被解釋變數時,黃金現貨則是有領先美元指數的現象,顯示黃金現貨與美元指數具有雙向影響的關係。
    3.當黃金現貨與美元指數偏離持有成本理論的均衡關係時,美元指數收盤價要回到均衡時需要調整的幅度較黃金現貨價格為大,顯示對黃金現貨價格具有價格領先的地位。
    4.黃金現貨與美元指數都有波動群聚的現象。在波動外溢效果方面,黃金現貨價格對美元指數收盤價有較大的波動外溢效果。
    This paper examined the relationship between gold spot and USD index using exponential GARCH model. In rational, efficiently markets, the USD index and the gold spot price should be contemporaneously correlated. Nevertheless, several studies found this paradoxical, since the lead–lag relationship between gold spot price and USD index. The empirical results indicated that:(1)The gold spot price and USD index are highly cointegrated.(2)Gold spot price and USD index affect each other.(3)USD index seems to lead Gold spot price with more powerful way.(4)For the volatility spillovers, the gold spot price have stronger volatility spillovers to USD index.
