Urban regeneration is an urban redevelopment process inevitable in urbanization, and it is gradually becoming a hot issue covering many disciplines such as economics, social management, public policy, and ecological environment. In this paper, we employed the bibliometric method and use the visualization tool, Citespace, to map knowledge domains of urban regeneration at home and abroad. Then, a quantitative comparative analysis on urban regeneration at home and abroad has been done in three aspects: evolutionary process, characteristics of published journals and research institutions, and research hotspots. Finally, the gaps and future research directions of urban regeneration research in China are put forward. The research indicates that: 1) The number of literatures published on urban regeneration at home and abroad shows a fluctuating upward trend, especially in the rapid development stage, when 117 articles and 238 articles were published each year. 2) Literatures mostly published in journals referring urban planning, regional research, urban design, and architecture. Compared with foreign journals, literature of urban regeneration in domestic is more concentrated. The top ten journals in China accounted for 46.65% of the total number of publications, while only 29.84% in foreign countries. 3) There is a preliminary cooperation network between research institutions both at home and abroad, but the degree of network connection and cooperation is still low. Compared with foreign institutions, links between domestic research institutions are relatively closer. 4) The foreign research hotspots mostly focus on partnership and participation, gentrification, sustainable development, urban transformation, and cultural creativity, while domestic research hotspots are reflected in urban renewal and estate development, protection and regeneration of historical blocks and industrial relics, exploration and practice of urban regeneration in Guangzhou-Shenzhen, and the preliminary discussion on participation, and so on.
