摘要:
新冠疫情的爆发对许多行业都产生了影响，为研究本次新冠疫情的严重程度对医疗器械概念股的影响，以76支相关股票为样本，运用EXCEL和R语言对数据进行处理和分析。将医疗器械的搜索指数、每股日收益率和每股日换手率设置为被解释变量，主要采用面板数据的固定效应模型，并辅以稳健性检验，发现新冠疫情的严重程度与投资者对医疗器械的关注度和医疗器械概念股的交易活跃度显著正相关，对医疗器械概念股的股价无显著影响。

In order to find the impact of the se-verity of the COVID-19 on the medical instruments concept stocks, 76 related stocks were used as samples, and using EXCEL and R software to process and analyze data. Set the search index of medical instruments, daily earnings per share, and daily turnover rate per share as explained variables. The fixed-effect model of panel data is mainly used, supplemented by a robustness test.
