基于CiteSpace的城市轨道交通PPP模式研究发展分析

城市轨道交通与PPP模式的结合,能有效缓解政府财政压力、提高项目运行效率。以2011—2021年中国知网（CNKI）数据库收录的449篇城市轨道交通PPP模式文献为研究对象,运用文献计量方法,借助CiteSpace 5.7.R1对该领域发文量、发文时间、研究机构、发文作者、发文期刊来源以及关键词频次、关键词聚类、关键词时间进行可视化分析。通过知识图谱分析该领域当前研究现状,综述研究动态,使研究中难以观察或统计的关键问题得到直观呈现。提出加强作者与作者、机构与机构、作者与机构间的合作,增强交叉学科支持力等相关建议。从关键词角度分析,将近10年内的研究趋势划分为3个阶段,梳理各阶段研究重点,总结经验,为未来的理论研究以及实践提供一定的借鉴和参考。

Analysis of Research Development on Urban Rail Transit PPP Mode Based on CiteSpace

The combination of urban rail transit and PPP mode can effectively alleviate government fiscal pressure and improve project operation efficiency. The literature of China National Knowledge Network (CNKI) database included?449 urban rail transit PPP mode studies from 2011 to 2021 is collected as the study object the documentary metrology method is used, with the number of documents, issuance time, research institutions of the field with CiteSpace 5.7.R1, Text author,to make vocalization analysis of the source and keyword cluster, keyword cluster, keyword time.Through knowledge map, the current research status of this field is analyzed, and the research dynamics are reviewed, and the key issues that are difficult to observe or statistically in the study have been visited.It is proposed to strengthen cooperation between authors, institutions, institutions, authors and institutions, and enhance relevant proposals such as cross-discipline support.Analysis of the research trend of nearly ten years from the keyword angle analysis is three stages.Combing all stages of research focus, summing up experience to provide a certain reference and reference for the future theoretical research and practices.
