本研究探討新冠肺炎疫情期間旅遊產業相關研究議題，以書目計量法作為基礎，輔以VOSviewer執行共字分析，針對共字分析之結果做文獻內容閱讀，找出各集群下的研究主題。
本研究採用Web of Science 核心合輯為文獻來源資料庫，篩選2020年1月1日至2020年10月15日期間，新冠肺炎相關關鍵字之主題的文獻，並以資料庫中的Hospitality Leisure Sport Tourism分類為主要探討領域，初步篩出152個結果數進入共字分析，找出前五大集群中之97個結果數，藉由閱讀97篇文獻內容，獲得19個新冠肺炎下旅遊產業之研究主題。
本研究結果發現，新冠肺炎下的轉型議題、永續議題、旅遊相關子產業、旅行目的地、受疫情影響之利害關係者、封鎖期間的休閒活動與社會情緒為主要的研究主題。

This study explores research topics related to the tourism industry during COVID-19. It is based on bibliometric analysis and uses VOSviewer to perform co-word analysis. With the literature review of previous studies using co-word analysis, the research topics under each cluster are identified.
This study uses the Web of Science Core Collection as the document source database to filter the subject content of keywords related to COVID-19 from January 1 to October 15, 2020 and uses the Hospitality Leisure Sport Tourism classification in the database as the main area of discussion. 152 results were initially screened out, which the co-word analysis was applied to find out 97 results in the top five clusters. By reading 97 papers, the researcher obtained 19 research topics on the tourism industry in the time of COVID-19.
The results of this study discover that transition issues, sustainability issues, tourism-related sub-industries, tourism destinations, stakeholders affected by the epidemic, leisure activities during the lockdown period, and social emotions are the main research topics.
Keywords: COVID-19, tourism industry, bibliometric analysis, co-word analysis, WOS, VOSviewer
