目的：分析国内外大型运动会风险评估研究现状和热点及变化趋势。方法：收集2005年1月1日—2023年3月31日国内外大型运动会风险评估研究的相关文献，统计发文量情况，采用CiteSpace软件绘制关键词共现图、聚类图和Burst检验突现图，分析大型运动会风险评估的研究热点和趋势。结果：共纳入1 123篇文献，发表相关文献数量国外显著多于国内，国外呈逐年上升趋势，国内呈逐年下降趋势。食品安全、蚊媒疾病、风险预警是国内该领域主要研究热点。气候变化、饮食障碍、危险因素是国外该领域主要研究热点。风险矩阵是近期国内该领域研究主要趋势，而气候变化是近期国外主要研究方向。结论：国内外大型运动会风险评估的发文量、研究热点及趋势存在差异。国内对该领域的研究投入需进一步加强，国内外学者需加强该领域的多学科和多方向交叉性研究。

Objective：To analyze the current state，areas of focus，and changing trends in risk assessment research for large-scale sports events，both domestically and internationally. Methods：Literature from January 1，2005，to March 31，2023，was collected. The quantity of published articles was analyzed. We used CiteSpace software to create co-occurrence maps，cluster maps，and burst detection maps of keywords for identifying research hotspots and trends in the risk assessment of large-scale sports events. Results：A total of 1，123 Chinese and English literature were included. The number of published literatures on this topic was significantly higher in foreign countries than in domestic countries，with an upward trend each year in foreign countries and a downward trend each year in domestic countries. Food safety，mosquito-borne diseases，and risk warning were the main research hotspots in the domestic field. Climate change，eating disorders，and risk factors were the main research hotspots in the foreign field. Risk matrix was the recent main trend in domestic research in this field. Climate change was the main research direction in foreign countries. Conclusion：There are differences in the publication volume，research hotspots and trends of risk assessment for large-scale sports events between domestic and foreign countries. Further research investment is needed in the domestic field. Scholars from both domestic and foreign countries should strengthen interdisciplinary and multidirectional research in this field.
