中文摘要
本文利用向量自我迴歸模型研究台灣產業股價報酬率在疫情前後對台股大盤股價報酬率之影響差異,以及台灣公司股價報酬率在疫情前後對產業股價報酬率之影響差異,研究期間為2012年1月2日至2022年2月25日,並以2020年1月15日分為疫情前與疫情後,樣本資料取自TEJ台灣經濟新報資料庫,並且利用衝擊反映函數與變異數分解以探討在疫情前後的台灣股票市場,其大盤報酬率、產業報酬率與公司報酬率之間的關係及其影響差異。
本文實證結果發現,在疫情前後,台股大盤報酬率對產業報酬率及產業報酬率對公司報酬率的解釋程度之結果有明顯差異,並且大部分的產業報酬率對台股大盤報酬率及公司報酬率對產業報酬率皆沒有顯著的正向或負向反應,然而在疫情後卻有顯著的正向或負向反應。
Abstract
This thesis investigates whether the relationship between industry’s stock return and the stock market rate of return change before and after the epidemic and the relationship between the company’s stock return and industry’s stock return change before and after the epidemic by using the impulse response functions and variance-decomposition approaches. The sample period starts from January 2, 2012 to February 25, 2022 and January 15, 2020 as the cut-off point of the pre-pandemic era. The sample data were taken from the Taiwan Economic Journal (TEJ).
The empirical result of this thesis shows that there is a significant difference in the relationship between industry’s stock return and the stock market rate of return. Furthermore, there are no significant positive or negative responses from the industry’s rate of return to the stock market rate of return and from company’s rate of return to industry’s rate of return before the pandemic hits. However, there are notable positive or negative responses after the outbreak.
