The empirical results show that Shanghai Stock Exchange-listed China enterprises which engage in domestic M&As, whether the acquiring firm and the target firm are in the same industry or among different industries, have significantly positive cumulative abnormal returns near the announcement date. While the Shenzhen Stock Exchange-listed Chinese enterprises which engage in domestic M&As, have no significant cumulative abnormal returns. esides, considering the cumulative abnormal returns after the announcement date, the Shanghai Stock Exchange-listed Chinese enterprises which engage in domestic M&As, whether the acquiring firm and the target firm are in the same industry or among different industries, have significantly positive cumulative abnormal returns in the event window (0,1). While the Shenzhen Stock Exchange-listed Chinese enterprises which engage in domestic M&As, have negative cumulative abnormal returns in the event window (0,1). Especially, if the acquiring firm and the target firm are in the same industry, in the event window (0,14), there are significantly negative cumulative abnormal returns -1.9155%. Considering the cross-border M&As, the insignificantly cumulative abnormal returns of the Shanghai Stock Exchange-listed China enterprises are higher than those of the Shenzhen Stock Exchange-listed China enterprises. Due to the insufficient samples, we are unable to use strictly statistical tests to analyze the datas. But our conclusions provide further studies a trend to follow.目 錄一章 緒論 1.1 研究背景及動機 1.2 研究目的 2.3 研究設計與方法 4.4 研究範圍與限制 4.5 研究流程 5.6 研究架構 6二章 文獻回顧與探討 7.1 國內併購相關文獻 9.2 跨國併購相關文獻 16.3 上海證交所與深圳證交所上市公司的差異 24.4 總結 25三章 研究設計 26.1 樣本與資料蒐集 26.2 事件研究法 27.3 平均異常報酬率之檢定 30.4 累積異常報酬率之檢定 32四章 實證分析 33.1 標準化平均異常報酬率 34.2 標準化平均累積異常報酬率 41五章 結論與建議 46.1 結論 46.2 建議 48考文獻 49錄-圖 55錄-表 61application/pdf632471 bytesapplication/pdfen-US國內併購跨國併購併購宣告效果平均異常報酬累積異常報酬Domestic M&AsCross-border M&AsAnnouncement Effects併購宣告效果實證研究:以中國併購企業為例Announcement Effect: An Empirical Study of omestic and Cross-Border M&As by China firmsthesishttp://ntur.lib.ntu.edu.tw/bitstream/246246/182589/1/ntu-97-R95724036-1.pdf
