伴随着世界贸易格局的变化，国际产业转移和产业结构不断升级，经济服务化趋势越发显著，服务业持续蓬勃发展。本文以香港的旅游服务贸易作为主要对象，对香港与英国的双边旅游服务贸易进行分析，透过香港旅游服务贸易的竞争力指数趋势介绍香港国际旅游服务贸易的发展；通过计算香港对英国市场渗透率指数和产业内贸易竞争力指数，初步分析香港服务贸易在全球的贸易竞争力，并区分两地区名义GDP差和实际GDP差，分别搭配香港对世界服务进出口量的开放程度、香港对世界物品进出口量的开放程度、香港对世界的外商直接投资流入和流出四个指标作为自变量，对香港对英国市场渗透率和产业内贸易竞争力指数进行多元回归，深入分析影响服务贸易国际竞争力的影响因素。研究结果表明外商直接投资、服务开放程度、两地区GDP差对香港旅游服务贸易皆有显著的影响。
