服务贸易是全球经济贸易增长的重要引擎，也是金砖国家未来合作中的重要领域。本文介绍了金砖五国的旅游服务贸易发展概况，并结合IMS、TC、RCA和CA指数，对国际竞争力的综合指数做出整体分析，得到中国的旅游服务贸易国际竞争力在金砖五国中的综合排名结果；然后以波特钻石模型为理论基础，选取中国1998~2019年的数据，利用格兰杰因果关系检验分析，得出人均GDP、国内旅游收入和星级饭店数量对中国的旅游服务贸易国际竞争力影响最为显著；即国家经济实力的提高，旅游服务贸易的需求拉动以及旅游相关支持性产业的发展，都会刺激中国旅游服务贸易国际竞争力的提升。本文以此提出相应的政策发展方向，以期为中国旅游服务贸易的转型升级提供可供参考的建议。
