城市精明发展研究热点与前沿可视化分析

The Visualization Analysis of Hot Spots and Forward Positions in the Aspect of Urban Smart Development Research

以CNKI中国知网总库和Web of Science核心合集数据库为数据源,利用可视化分析工具Citespace V对2000-01-01-2019-05-01城市精明发展研究的相关文献进行分析。根据热点关键词共现和聚类分析、突现词前沿路径辨识分析、发文作者及机构合作网络分析以及发文期刊网络分析等方法绘制国内外相应的知识结构图谱,并立足城市精明发展研究的理论内涵、量化测度、实践应用层面进行评述。结果表明:1)国内外城市精明发展研究领域形成了初具规模的研究网络,但知识结构网络紧密性有待加强。2)国内外研究主题聚类知识群组数量较多,关键词共现聚类演化路径较长且相对分散,尚未形成势力强劲的时区流动和继承脉络。3)国内研究热点前沿逐渐从宏观理论分析转向城市微观实践应用以及城市收缩新兴态势。4)国内外研究人员学科背景广泛但互引关系稀松,亟待加强交流探讨;国内研究机构学科划分细致广泛,区域科研能力差异显著,东部地区和北京表现突出。5)国内经济管理与可持续发展、地理学、建筑科学与工程领域城市精明发展研究载文成果较为丰富。

Urban spatial layouts with leaping disorderly growth and far too compact shrinkage conflict with scientific and sustainable urban development processes to a certain extent. How to realize reasonable and moderate urban smart development has become a popular research topic in several disciplines in recent years.Using a data source retrieved from "China Knowledge Resource Integrated Database" and "Web of science," we analyze literature published between January 2000 and May 2019 that focused on urban smart development using the visual analysis tool CiteSpace V. We also drew corresponding maps of knowledge structure in domestic and foreign countries using co-occurrence and cluster analysis of key words, identification and analysis of burst words and frontier paths, analysis of collaborative networks of authors and institutions, and network analysis of publication periodicals. Moreover, we analyze and provide detail on comments related to aspects such as theoretical connotation, quantitative measurement, and practical application of urban smart development research.The findings of this study demonstrate the following: First, a research network for a whole new field of urban smart development study has come into existence, and in contrast, knowledge structure network tightness needs to be further strengthened in domestic and foreign countries. Second, many clustering knowledge groups of research themes exist around the world, and the yearly evolution path of key word co-occurrence clustering is relatively long and occurrence times are relatively scattered, which does not indicate powerful flowing time zones and succession venation. Third, research hot spots and forward positions gradually revert to the application of microscopic aspects and urban shrinkage tendencies from a macroscopic theoretical analysis in China.Researchers worldwide cover a widespread subject background but have loose inter-citation, thus communication and discussion must be strengthened urgently. Research institutions in China have detailed and extensive discipline divisions, and in addition to this, there are significant regional scientific research ability differences when taking the eastern region and municipality of Beijing as a priority. Lastly, urban smart development research in economic management, sustainable development, geography, architectural science, and engineering in China has achieved remarkable results. We suggest that strengthening the definition of connotation and construction of judgment frameworks and taking deep consideration of multi-angle forward positions while further promoting academic communications between authors and research institutions is greatly significant to improve the degree of correlation of research networks. As a result, these changes would form a more extensive research network and knowledge structure system.
