    Abstract: 本研究主要在於檢測目前國內台股指數期貨漲跌幅制度下,對於市場效率性的影響。有別於過去的研究,本研究進一步探討不同漲跌幅設限之摩根台指期貨市場,與台股指數期貨是否具有顯著性的不同,並觀察各重大事件街擊下,兩市場效率性的差異,實證模型採用傳統變異數比率與無母數變異數比平進行檢測。實證結果顯示台股指數期貨價格乃服從隨機漫步之假設,但摩根台指期貨則無,且在各事件衝擊方面,台股指數期貨普遍具有資訊的效率性,但新加坡市場則呈現拒絕隨機漫步的現象。據此,本研究建議市場設置較嚴刻之漲跌幅制度,將有助於提高資訊的傳遞反降低交易人之資訊不對稱性,同時也隱含價格限制較寬鬆的新加坡市場,投資人反應不足或過度反應的現象,也許普遍存在於期貨的價格。
