国外城市群研究:轨迹、热点及趋势——基于CiteSpace V的文献可视化分析

Research on Urban Agglomerations at Abroad:Tracks,Hotspots and Trends--Visual Literature Analysis Based on CiteSpace V

本文以Web of Science核心合集1975~2018年发表的3080篇城市群文献为基础,借助CiteSpace软件,进行合作共现、文献共被引、突现词探测等分析,系统梳理城市群研究知识基础、领域前沿、现状热点与发展动态。结果显示:(1)国外城市群研究40年来发文量和新兴关键词数量呈逐年上升趋势;(2)研究者分布于西欧、北美和东亚三大核心地带,中国学者发文量颇丰,作者共被引多集中于西方学者;(3)关键词共现表明,城市、集聚、城镇化等出现频次较多,并形成城市、知识溢出、城镇化、大气污染、生产力、城市形态等六大聚类;(4)突现词探测较为清晰地展现了城市群研究发展脉络,土地利用变化、驱动力、城市蔓延、气候变化、城镇化、中国等成为最新研究主题。

Based on the 3080 urban agglomerations published in the core collection of Web of Science in the past 1975~2018 years,this paper uses CiteSpace software to analyze co-operative co-occurrence,co-citation and emergent word detection,and systematically sorts out the knowledge base,frontiers,current situation and development trends of urban agglomeration.The results show that:(1)In the past 40 years,the number of papers and new key words of urban agglomeration research in foreign countries has been increasing year by year;(2)Researchers are distributed in the three core areas of Western Europe,North America and East Asia,and Chinese scholars have a large number of publications,the author’s co-citation mainly focuses on western scholars;(3)The co-occurrence of key words shows that cities,agglomerations and urbanization occur more frequently,and form six clusters:cities,knowledge spillovers,urbanization,air pollution,productivity and urban morphology;(4)The detection of emergent words clearly shows the context of urban agglomeration research and development.Land use change,driving force,urban sprawl,climate change,urbanization,China,etc.have become the latest research topics.
