摘要


企業併購宣告,往往會造成股價的波動,並成為企業與投資大眾所關注的議題之一。為了達成規模經濟,企業擴大規模而進行併購,如此使他們能降低成本與提升競爭力。 本研究主要探討台灣企業併購後的股價異常報酬是否大於企業併購前股價異常報酬,與在股權交換、現金收購與混合支付這三種支付方式下對於股價異常報酬是否有顯著的差異。 研究樣本期間為2003年8月至2013年8月之上市上櫃主併公司與被併公司,共10年期間,並以事件研究法進行分析,經本文實證後所得的結論歸納如下:比較併購宣告日前後15日中,發現併購後的平均股價變動率則大於併購前的平均股價變動率,表示併購宣告會造成公司價值正向的影響,另觀察在股權交換、現金收購及混合支付三種支付方式間的差異對公司價值有何影響,在觀察三種支付方式的平均股價變動率中,結果顯示現金收購的變動率是高於其他支付方式的變動率,因此現金收購的股價異常報酬比上其他支付方式是有較高的報酬率,並觀察三種支付方式間之差異性檢定,結果顯示在股權交換與現金收購中在前一季為基期下宣告日當日及後15日有顯著差異,在現金收購與混合支付中則呈現都不顯著,在股權交換與混合支付中在前一個月為基期下宣告前15日有顯著差異。
