本文採用異質偏誤相關係數及GJR-GARCH模型來檢測金融海嘯全球REITs包括美國、北美洲、歐洲、亞洲、大洋洲地區共移程度及波動外溢的相關性,並是否產生蔓延效應之影響,樣本期間為2007年9月14日至2009年3月14。 實證結果顯示:在金融海嘯發生後,美國對各國REITs報酬之間相關係數的共移程度明顯增加,且另外對部分國家的REITs造成明顯的波動外溢效果,並將共移程度與波動外溢彙整後可發現加拿大、德國、日本、澳洲有短期的蔓延效應,而台灣、香港有長期的蔓延效應。由此可知,隨著金融海嘯發生,被蔓延的國家大部分與美國有經濟貿易較密切往來或鄰近之國家,所受的損失也相對較嚴重。
The main object of research for the dynamic correlations among test contagion effect of the crisis on America, North America, Europe, Asia and Oceania REITs market under financial tsunami by using correlation coefficients and GJR-GARCH model. The sample period of this research is from September 14, 2007 to March 14, 2009. The empirical results show that the after financial tsunami the correlation coefficient between the American and worldwide REITs co-movement markedly increased. In addition, worldwide REITs were caused more obvious asymmetric volatility in some countries. The co-movement and volatility spillover collected show that the Canada, Germany, Japan and Australia have short-term contagion effects and Taiwan and Hong Kong have long-term contagion effects. The results show with the financial tsunami and crisis occurring the commercial trade between neighboring countries of contagion influence and partner countries more severe with American.
