dc.description.abstract自2015年下半年起,台灣經濟重心的半導體產業中的封裝測試供應鏈,開始了一連串併購與投資的事件。以日月光併購矽品的事件為序幕,接續而來的中資紫光集團入股矽品精密、力成科技、南茂科技等封測大廠;中資首次入台投資核心高科技業的事件,在產業界引起極大的震撼。基於半導體產業為台灣主要核心競爭力產業,本研究為首度對於中國資金投資台灣半導體產業的事件進行分析,不僅對於封測業內的領先企業以及其他封測業者進行實證比較,同時也是首次對於進行投資的中國企業進行分析,可做為台灣半導體產業界制定因應策略及發展方向的重要參考。 本研究以事件研究法來對於中資紫光集團、被投資入股的封測公司以及其他封測業者的股價反應進行研究。發現主要被紫光投資的公司於事件日出現正向顯著的異常報酬,而資訊不對稱情況也影響著被紫光投資的公司。隨後的異常報酬依效率市場假說理論,充分反應公開資訊後隨即反轉向下。而對於其他業者而言,由於市場區隔以及併購事件效益不明等因素影響之下,股價並未出現如預期的負向異常報酬。而中國企業的股價,由於併購美國半導體大廠的進展並不順利,其效益未能反應於股票市場,所以未如預期的假說從這些併購投資事件得到顯著正向的異常報酬。本研究實證了投資與併購事件對於資本密集的半導體產業是正向的,在中國市場崛起的趨勢下,台灣業者須加速進行整合以提高其競爭力,並維持其領先的地位。對於核心產業因中資投入而威脅國家競爭力所產生的疑慮,使得政府角色在最後的審查中,扮演了投資事件是否能成功的決定性因素。zh_TW
dc.description.abstractSince August 2015, there was a series of merging and investing events occurred in semiconductor assembly and test industry which is the core industry in Taiwan. From the event of ASE merging SPIL began, following the China Tsinghua Unigroup to announce investing SPIL, Powertech and ChipMOS companies which are leading testing and assembly companies in the world. These events inspired great reaction in Taiwan semiconductor industry. By using the Event Study, our researching results revealed the invested companies’ stock prices showed positive abnormal stock return with significant level. These results showed the impact of information asymmetry on major invested company at the same period. Following descending trend on abnormal stock return also approved the Efficient-Market Hypothesis. For other companies in the assembly and test industry, there was no significant level to approve negative abnormal stock return. The evidence disclosed China Tsinghua Unigroup didn’t get the benefit from the stock market on these events.en_US
