Abstract: Based on visual analysis of the metonymy research literature collected from the WOS and CNKI， the research status and trend of metonymy are investigated. Five major findings are obtained. Firstly， metonymy research has been developed deeply to some extent at home and abroad， but the influence of the domestic research output needs to be improved. Secondly， researchers who have few academic exchange and cooperation tend to conduct researches individually. Thirdly， research hotspots at home and abroad cover the noumenal research on metonymy， the relationships between metonymy and metaphor， and the application of metonymy to different language phenomena； but the hot topics explored by the scholars abroad are broader and diverse empirical research methodologies are employed. Fourthly， the evolutionary progress of research hot topics at home and abroad does not develop at the same pace. Lastly， research topics are broader abroad than that at home. All in all， there still exists much room for the further research of metonymy.

摘要： 利用CiteSpace对2000—2020年间WOS和CNKI数据库中的转喻研究文献进行可视化分析，梳理国内外转喻研究的现状与发展趋势。国内外转喻研究深入发展，但国内转喻研究成果的国际发文影响力还有待提高；多数学者更倾向于独立研究，学术交流与合作较少；国内外的研究热点均涉及转喻的本体研究、转喻与隐喻的关系及转喻在不同语言层面的应用。国外学者的研究热点更广泛，且采用多样的实证研究方法；国内外研究热点的演进趋势不完全同步。另外，国外前沿研究话题较为多元，而国内前沿话题相对单一。总之，转喻研究虽已取得巨大成就，但仍存在诸多研究空间，需要国内外学者继续深入探讨、挖掘。
