Recently, enterprises in Taiwan have taken sequential mergers and acquisitions more often as strategies to expand their business maps. Our results show that sequential acquisitions perform worse than one-time acquisition in terms of one-year abnormal operating performance. However, for three-year abnormal operating performance, there is no significant difference between one-time acquisitions and sequential acquisitions. In addition, we suggest that acquiring firms with abundant resources or low debt-to-equity ratio should avoid sequential acquisitions, while firms with less resources or limited debt could consider sequential acquisitions as strategies to enter into new markets or new business fields.Chapter 1 Introduction.....................................1 Chapter 2 Literature and Hypotheses Development............4 2.1 Abnormal Operating Performance Following Mergers and Acquisitions...............................................4 2.2 The Real Options Theory and Sequential Mergers and Acquisitions...............................................6 2.3 The Resource-Based Theory and One-time Mergers and Acquisitions...............................................9 2.4 Moderating Effect of Organizational Resources on Operating Performance.....................................11 Chapter 3 Data and Methodology............................12 3.1 Data..................................................12 3.2 Methodology...........................................13 3.2.1 Calculation of Abnormal Operating Performance.......14 3.2.2 Multivariate Regression.............................16 Chapter 4 Empirical Results...............................18 4.1 Descriptive Statistics................................18 4.2 Abnormal Operating Performance Following Mergers and Acquisitions..............................................19 4.2.1 Univariate Analysis.................................19 4.2.2 Multivariate Analysis...............................20 4.2.2.1 Direct Effect of One-time and Sequential Mergers and Acquisitions..............................................20 4.2.2.2 Moderating Effect of Organizational Slack.........20 Chapter 5 Conclusions and Suggestions.....................21 References................................................24858707 bytesapplication/pdf論文公開時間：2016/01/27論文使用權限：同意無償授權階段性併購異常營運績效實質選擇權資源寬裕thesishttp://ntur.lib.ntu.edu.tw/bitstream/246246/262497/1/ntu-102-R00723079-1.pdf
