The metaverse has attracted wide attention from all walks of life around the world, and relevant research and applications continue to emerge. In order to fully understand the current status, hot spots and trends of metaverse research and industrial application at home and abroad, using databases such as China National Knowledge Infrastructure (CNKI) and Web of Science as data sources, to retrieve key literatures in the field of metaverse research before 2023,and comprehensively use analytical tools such as VOSviewer and CiteSpace to analyze the number of published articles, keyword co-occurrence network, keyword clustering, keyword co-occurrence time zone map, keywords with the strongest citation bursts and highly cited papers. The results indicate that the metaverse is an integration of multiple technologies, related research has gone through a long accumulation period, the number of publications and total citation frequency within the field have shown explosive growth in the last two years, with China leading the number of publications. The research content in this field covers a wide range of disciplines. Research hotspots and frontiers cover virtual reality, artificial Intelligence, blockchain, and many other aspects.
