City image research, as a burgeoning paradigm within communication studies, lacks a comprehensive analysis and empirical research on foreign city images. Employing bibliometric methods, this study utilizes CiteSpace to visually analyze research literature on city images published in SSCI journals between 2013 and 2023. It visualizes co-occurrences of keywords, clusters, timeline of main themes, and knowledge maps. The findings reveal that foreign city image research is characterized by diverse perspectives, spanning disciplines such as geography, sociology, and psychology, constructing complex theoretical frameworks. Methodologically, it exhibits depth and complexity, encompassing macro and micro levels, incorporating traditional quantitative methods and integrating new computational methods like computer vision, network analysis, and spatiotemporal analysis. Moreover, numerous studies combine city image analysis with urban planning, marketing, community development, utilizing big data and artificial intelligence technologies for in-depth analysis. This paper summarizes the field and current status of foreign city image research, offering theoretical perspectives and methodological references for domestic studies.
