本研究探討上市櫃公司經營績效影響因素之探討，比較COVID-19疫情前後期之差異。經營績效包括財務績效ROA、ROE及市場績效Tobin’s Q；相關影響因素包括公司治理相關變數、財務特性、研發費用及公司背景因素。研究樣本期間包括2019年COVID-19疫情發生前及2020年疫情發生後之上市櫃公司。透過統計迴歸分析。
本研究實證結果，主要發現在2019年疫情發生前，本國法人機構持股比例、外資法人機構持股比例、銷貨收入成長率、負債比率、研發費用、公司規模，對經營績效指標ROA、ROE、Tobin’s Q有顯著相關聯；在2020年疫情發生後，大股東持股比例、本國法人機構持股比例、外資法人機構持股比例、銷貨收入成長率、負債比率、研發費用、公司規模，對經營績效指標ROA、ROE、Tobin’s Q有顯著相關聯。
在疫情前後期之變動差異方面，2020年外資法人持股、營收成長率、負債比率、研發費用率、公司規模、上市櫃公司與上年度ROA與財務經營績ROA及ROE有顯著的相關聯，外資法人機構持股比例、營收成長率及上市櫃公司在市場績效Tobin’s Q有顯著的相關聯。根據迴歸分析了解，2020年疫情發生後，這些影響因素跟經營績效的關聯性皆呈下降，亦即反應疫情帶給企業存在更多的不確定性及風險。

The study explores the factors influencing the operating performance of listed companies, and compares the differences between the pre- COVID-19 and post-COVID-19 epidemic. Operational performance includes financial performance ROA, ROE and market performance Tobin’s Q; related factors include corporate governance-related variables, financial characteristics, research and development expenses and company background factors. The study sample period included listed companies before the COVID-19 outbreak in 2019 and after the outbreak in 2020. Through statistical regression analysis.
The empirical results of this study mainly found that the shareholding ratio of domestic legal person institutions, the shareholding ratio of foreign legal person institutions, sales revenue growth rate, debt ratio, research and development expenses, and company size before the outbreak of the epidemic in 2019 had a significant impact on the operating performance indicators ROA, ROE and Tobin's Q is significantly correlated; the shareholding ratio of major shareholders, the shareholding ratio of domestic legal person institutions, the shareholding ratio of foreign legal person institutions, the growth rate of sales revenue, debt ratio, research and development expenses, and company scale after the outbreak of the epidemic in 2020. The performance indicators ROA, ROE, and Tobin's Q were significantly correlated.
In terms of changes before and after the epidemic, foreign legal person shareholding, revenue growth rate, debt ratio, R&D expense ratio, company size, listed cabinet companies in 2020 are significantly correlated with the ROA of the previous year and financial and operating performance ROA and ROE , there is a significant correlation between the shareholding ratio of foreign legal entities, the growth rate of revenue and the market performance of listed companies in Tobin's Q. According to the regression analysis, after the outbreak of the epidemic in 2020, the correlation between these influencing factors and business performance has declined, which means that responding to the epidemic has brought more uncertainty and risks to enterprises.
