The aim of this paper is to map the intellectual structure of social and sustainable public procurement research by means of delimiting the scientific domain\u2019s research traditions, its disciplinary composition, and influential research topics. Given that there is a literature gap in bibliometric studies applied to this field, we conducted a co-citation analysis to identify the intellectual structure of this area of knowledge. Co-citation analyses identify networks of interconnections and, consequently, detect the most (and the least) active research areas, being a good complement to traditional literature reviews. This article contributes to science development because it is the first paper to carry out a bibliometric analysis in the field of social and sustainable public procurement, as well as the first one to conduct a co-citation analysis among public procurement research. Consequently, it is also the first article to detect which papers have become burst in this research field. The results show twelve different clusters of publications that were cited by researchers who wrote papers on social and sustainable public procurement. In other words, the sources of knowledge that scholars used as references are analysed, identifying papers that can be considered turning points, as well as those that became specially cited over a discrete period of time. Six different research trends were identified over the last decade in regard to social and sustainable public procurement research. The conclusions highlight the relevance of the findings, especially because they provide guidance to researchers when conducting literature reviews, given that the most significant journals and papers are identified.<\/jats:p>","DOI":"10.3390\/su13020774","type":"journal-article","created":{"date-parts":[[2021,1,15]],"date-time":"2021-01-15T01:33:29Z","timestamp":1610674409000},"page":"774","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":33,"title":["The Intellectual Structure of Social and Sustainable Public Procurement Research: A Co-Citation Analysis"],"prefix":"10.3390","volume":"13","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-2276-1655","authenticated-orcid":false,"given":"Jose","family":"Torres-Pru\u00f1onosa","sequence":"first","affiliation":[{"name":"Facultad de Empresa y Comunicaci\u00f3n, Universidad Internacional de la Rioja (UNIR), 26006 Logro\u00f1o, La Rioja, Spain"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6807-0185","authenticated-orcid":false,"given":"Miquel Angel","family":"Plaza-Navas","sequence":"additional","affiliation":[{"name":"Instituci\u00f3n Mil\u00e1 y Fontanals de Investigaci\u00f3n en Humanidades, Consejo Superior de Investigaciones Cient\u00edficas (CSIC), 08001 Barcelona, Barcelona, Spain"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9888-833X","authenticated-orcid":false,"given":"Francisco","family":"D\u00edez-Mart\u00edn","sequence":"additional","affiliation":[{"name":"Department of Business Economics, Universidad Rey Juan Carlos, 28933 M\u00f3stoles, Madrid, Spain"}]},{"given":"Albert","family":"Beltran-Cangr\u00f3s","sequence":"additional","affiliation":[{"name":"Escuela de Turismo y Direcci\u00f3n Hotelera (EUTDH), Universidad Aut\u00f3noma de Barcelona, 08193 Bellaterra, Barcelona, Spain"}]}],"member":"1968","published-online":{"date-parts":[[2021,1,14]]},"reference":[{"key":"ref_1","unstructured":"OECD (2020).
