Studies around public–private partnerships (PPPs) have shaped a complex and colorful research field. A series of review studies have been performed to explore the knowledge base of this field. Despite their significant contributions, bibliometric research on the PPPs literature is still needed to capture more comprehensive, diverse and detailed information in this area from a holistic perspective, for reducing subjectivity and one-sidedness. Under this situation, this paper continues the bibliometric journey by conducting a comprehensive metrological and content analysis of the PPPs research field. By applying a newly developed Bibliometrix R-package tool, the overview of PPPs research is presented via metrological analysis using a series of indexes. The intellectual structure of this domain is then explored via content analysis using the methods of keywords analysis and citation analysis from both static and dynamic perspectives. Consequently, the panoramic view including the overview, pivotal points of topics, thematic evolution and research focuses of this domain are depicted visually and intuitively via a set of science maps. This new attempt crystallizes out key findings and valuable information of PPPs research, which can consolidate and broaden the bibliometric findings of previous PPPs literature studies and act as a guidance for analyzing the knowledge base of other research fields.

公私合作伙伴关系 (PPPs) 研究领域的综合计量和内容分析：新的文献计量之旅

围绕公私合作伙伴关系 (PPP) 的研究塑造了一个复杂而丰富多彩的研究领域。已经进行了一系列审查研究来探索该领域的知识库。尽管他们做出了重大贡献，但仍需要对 PPP 文献进行文献计量研究，以从整体的角度捕捉该领域更全面、更多样化和更详细的信息，以减少主观性和片面性。在这种情况下，本文通过对 PPPs 研究领域进行全面的计量和内容分析，继续文献计量之旅。通过应用新开发的 Bibliometrix R-package 工具，使用一系列指标通过计量分析呈现 PPPs 研究的概述。然后从静态和动态角度使用关键字分析和引文分析方法通过内容分析来探索该领域的知识结构。因此，通过一组科学地图，直观地描绘了该领域的概述、主题关键点、主题演变和研究重点等全景图。这一新尝试将 PPPs 研究的关键发现和有价值的信息具体化，可以巩固和拓宽以往 PPPs 文献研究的文献计量结果，并为分析其他研究领域的知识库提供指导。该领域的主题演变和研究重点通过一组科学地图直观地描绘出来。这一新尝试将 PPPs 研究的关键发现和有价值的信息具体化，可以巩固和拓宽以往 PPPs 文献研究的文献计量结果，并为分析其他研究领域的知识库提供指导。该领域的主题演变和研究重点通过一组科学地图直观地描绘出来。这一新尝试将 PPPs 研究的关键发现和有价值的信息具体化，可以巩固和拓宽以往 PPPs 文献研究的文献计量结果，并为分析其他研究领域的知识库提供指导。
