摘要

本研究旨在探讨台湾股市投资人如何反应严重特殊传染性肺炎(COVID-19)及严重急性呼吸道症候群(SARS)的首例确诊宣告。相异于偏重调查单一传染病之股价效果的早期文献，本研究调查COVID-19及SARS首例确诊宣告对股票报酬率、交易量及报酬波动性的影响。我们的实证结果显示COVID-19及SARS对于股东财富及股票交易频率产生明显的冲击；此外，COVID-19首例确诊宣告也导致投资人持股风险出现显著的增加。总结而言，COVID-19对股市投资人决策的影响力是高于SARS。 This study aims to examine how investors in the Taiwanese stock market respond to the announcement of the first confirmed case of COVID-19 and SARS. Unlike earlier studies focusing on the share price effect of an infection, this study explores the influences of the first confirmed case of COVID-19 and SARS on the stock returns, trading volume and return volatility. Empirical results reveal that both COVID-19 and SARS have an important impact on the shareholder’s wealth and stock trading frequencies. Additionally, the announcement of the first confirmed case of COVID-19 increases significantly the risk of investing in shares. Overall, the influences of COVID-19 on the investor’s decision-making is greater than those of SARS.
