Abstract:	本研究係針對MSCI正式於2018年05月15日將中國A股納入其指數編製為事件，檢視該事件的宣告於短期內是否具有資訊內涵而產生異常報酬。實證結果顯示： 1.在平均異常報酬率方面，所有實際選樣股與新增成分股於宣告日平均異常報酬率顯著為正，訊息之宣告對投資人產生正面宣告效果；剔除股於宣告日平均異常報酬率為負值，訊息之宣告對投資人產生負面宣告效果，惟並不顯著。 2.在平均累積異常報酬率方面，所有實際選樣股與新增成分股於宣告日當日皆具有顯著正的平均累積異常報酬率，並於宣告日後1日達到最高點；剔除股於宣告日當日出現顯著負的平均累積異常報酬率，並於宣告日後1日達到最低點。;This research is aimed at MSCI officially on May 15, 2018, the inclusion of China A shares in its index as an event, to examine whether the announcement of the event has information connotation and abnormal returns.
