摘要


本研究探討公司進行權益分割後,產生之宣告效果,並探討公司進行權益分割背後之誘因。本研究以2002年至2011年於公開資訊觀測站中,以重大訊息公告進行權益分割之公司共69筆公告為樣本,以事件研究法計算宣告之異常報酬。本研究擬定六項誘因,評估產生異常報酬之主要誘因為何。六項誘因包括產業特性、產業聚焦、稅制優惠、出售股權、初次上市、資本支出。此外本研究亦分析盈餘管理程度對異常報酬率之影響。 本研究之實證結果顯示,對短期的投資人而言,若公司進行權益分割之又因為產業特性、稅制優惠、及出售股權時,市場的多為負面反應。而對長期來說,分割誘因為出售股權、資本支出時,則給予正向的反應。但若誘因為初次上市及盈餘管理實,則給予負向之反應。另外本研究將電子業及非電子業分別進行長期異常報酬分析,發現非電子業對於稅制優惠、初次上市、及資本支出三種誘因有正向影響,但若分割誘因屬於產業聚焦則有負向影響。本研究並發現進行權益分割之電子業公司其盈餘管理程度較非電子業高。

The study investigates the association between announcement effects and incentives of equity carve-outs. The sample includes 69 equity carve-outs material information announcements published on Market Observation Post System from 2002 to 2011. The study analyzes the impacts of short-term and long-term abnormal returns on incentives and also evaluates the incentives attributed to abnormal returns. The study identifies six types of equity carve-outs incentives including industry characteristic, industrial focus, tax deduction, share sales, initial public offering, and capital expenditures. Moreover the study also analyzes the impacts of degree of earnings managements on abnormal returns. The study finds that industrial characteristic, tax deduction and share sales attribute to short-term abnormal returns. The aforementioned incentives have negative effects on short-term abnormal returns. On the other hand, share sales and capital expenditures have positive effects on the long-term abnormal returns. The rest incentives- initial public offering and earnings managements would have negative effects on the long-term abnormal returns to the companies. Lastly, the study discusses samples separately depending on industrial characteristic electronic and non-electronic industry. The study finds that tax deduction, initial public offering and capital expenditure have positive effect in non-electronic industry, and industrial focus with negative effect. The study also finds that the degree of earnings managements in electronic industry is higher than non-electronic industry.
