本研究以2002年至2013年台灣主併公司為上市公司的併購案件為樣本，探討專家意見評價結果和品質對主併公司短期股價影響。本研究結果有兩項發現：
1. 於意見書揭露日時，若專家意見書評估價格高於雙方約定交易價格愈多時，即評價溢酬愈大，主併公司會有負向的累積異常報酬率。
2. 於意見書揭露日時，若併購溢酬越大、或是併購溢酬大與評價品質高，主併公司會有負向的累積異常報酬率。
故本研究認為，台灣獨立專家制度相較歐美國家仍不成熟，相關配套措施及規範未規畫周詳，對於獨立專家的獨立性、專業性之確保，以及出具意見時評價方法的選擇標準、意見書應記載事項等規範過少，使得專家意見書於揭露時評價結果易受到市場及投資人懷疑。另外評價品質與主併公司異常報酬的關聯性在少數的樣本下無法表現出顯著性，市場及投資人較傾向以併購溢酬做為交易出價是否過高之依據。 / This study analyses the relation between target firm appraisal outcome and quality disclosed in the fairness opinions and acquiring firm performances by using the samples of Taiwanese listed company in M&A transaction between 2002 and 2013. We find that the stock price reactions to the public disclosure of fairness opinions are negatively related to the difference between target firms valuations contained in the fairness opinion and the merger offer price. In addition, the greater the acquisition premium for or acquisition or high acquisition premium with high appraisal quality would result in negative stock price reactions as well.
Under these conditions, this study suggests that Taiwan's independent expert system in Taiwan still appeared to be immature, including that related supplementary measures are not careful planned, the independence of the independent expert, the professionalism of independent expert, and the criteria of valuation methods are not carefully regulated by the government. Therefore, the outcome and the quality of the fairness opinion may not to be trusted by the market and investors. Also, the association between appraisal quality and abnormal unable to be significant could result from the lack of number of samples.
