本报告聚焦于国际游客视角下的中国城市形象，通过分析YouTube平台上外国游客发布的以“China Travel”为主题的视频内容，深入探讨中国城市的对外传播影响力。报告通过采集免签政策实施后，外国游客在中国的旅行体验视频，通过大模型提取其字幕中的相关信息，并结合YouTube页面的量化数据，综合构建一个新颖且有效的城市对外传播影响力评估体系。该体系将评估各个典型城市的传播力，并据此生成城市对外传播力榜单。除此之外，还将从六个方面，即治安、便捷、友好、环境、食物、城建，对城市对外传播影响力进行深入案例分析，探讨成功传播策略的关键因素，并探讨提升中国城市的国际形象和吸引力的对策。
This report focuses on the image of Chinese cities from the perspective of international tourists，and explores the influence of Chinese cities’ external communication by analysing the content of videos posted by foreign tourists on the YouTube platform with the theme of “China Travel”. The report collects videos of foreign tourists ‘travel experiences in China after the implementation of the visa-free policy，extracts the relevant information in their subtitles through a large model，and combines them with quantitative data from YouTube pages to build a novel and effective system for assessing the influence of cities’ external communication. The system will evaluate the communication power of each typical city and generate a list of cities’ external communication power accordingly. In addition，an in-depth case study of a city’s external communication influence in six aspects（security，convenience，friendliness，environment，food，urban construction）will be conducted to explore the key factors of a successful communication strategy，and countermeasures to enhance the international image and attractiveness of Chinese cities will be discussed.
