基于文献计量方法的国内外城市更新比较研究

采用文献计量方法，利用Citespace工具对国内外城市更新研究进行知识图谱分析，从演化过程、发文期刊和研究机构的特征、研究热点等方面对比国内外城市更新研究的差异。研究表明：① 国内外城市更新研究的发文量呈现波动上升的趋势，在快速发展阶段尤为显著，每年发文量分别达到117篇和238篇；② 研究文献多集中在城市规划、区域研究、城市设计、建筑学等期刊。相对于国外，国内发文期刊更集中。国内排名前10的期刊发文量占比达46.65%，国外仅29.84%；③ 国内外的研究机构间初步形成合作网络，但网络联系与合作程度依然较低。相对于国外，国内研究机构间联系更紧密。④ 国外研究热点集中在伙伴关系与公众参与、绅士化、可持续发展、城市转型和文化创意等方面，国内研究热点体现在旧城改造与房地产开发、历史街区和工业遗产的保护与更新、广州?深圳城市更新的探索与实践、公众参与的初步探讨等方面。

Comparative Study on Urban Regeneration at Domestic and Foreign Based on Bibliometric Methods

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.
