本研究為瞭解新台幣及人民幣匯率對東亞六國股價報酬的資訊傳遞效果,研究期間以2012年1月1日至2017年3月1日為主,研究方法係採用GJR-GARCH-ST模型以及Clayton Copula、Gumbel Copula模型建構。AR(1)-GARCH(1,1)均數方程式估計結果顯示,新加坡、印尼、越南股價報酬P-Value不顯著皆,因此,不受台灣或中國前一天影響;泰國與馬來西亞均受台灣或中國前一天負向影響;菲律賓受台灣前一天P-Value有顯著效果,受中國前一天P-Value不顯著,因此,菲律賓受台灣前一天負向影響但不受中國前一天影響,在Clayton Copula模型及Gumbel Copula模型皆為顯著效果。期望透過本研究,了解新台幣匯率及人民幣匯率對東亞六國股票市場間是否存在市場報酬率具波動性,以提供投資者進行國際投資決策時之最適建議。
The analysis based on three models, GJR-GARCH-ST model, Clayton Copula model and Gumbel Copula model, to understand whether the transmission effect of a change in the exchange rate for TWD and CNY have an impact on stock returns of six countries in East Asia. Daily data from 1 January 2012 to 1 March 2012 are used. The estimated result of AR (1) – GARCH (1, 1) show the stock return P-Value of Singapore, Indonesia and Vietnam are not obvious.
