Abstract: 【Purpose/significance】This study endeavors to construct a comprehensive knowledge map in the domains of cross-cultural communication and public opinion management. It aims to illuminate the current publication trends, delineate the collaborative efforts and contributions of authors and institutions, and identify the prevailing research status, emerging hotspots, and the thematic variances and research frontiers within both Chinese and English academic literatures.【Method/process】Employing bibliometric analysis as the foundational methodological approach, this research meticulously interprets 161 core documents sourced globally. It leverages visual⁃ ization techniques to create a publication trend chart and develops a knowledge map through the analysis of author and institutional collaborations, keyword clustering, and prominence evaluation.【Result/conclusion】In the research field of cross-cultural communica⁃ tion of public opinion management, China has a great research space. That is, the field needs to form and strengthen the central lead⁃ ing institutions in the field by strengthening the domestic and foreign cooperation networks, and to promote the deeper research devel⁃ opment and richer academic output in the field of integration with big data.【Innovation/limitation】This paper encourages students to continue to pay attention to international issues in the future, especially to actively use big data and artificial intelligence technology to strengthen public opinion guidance, establish and cultivate college students' correct cross-cultural communication values, improve the national image and do a good job in public opinion management.
