Bibliometric analysis of scientific research on PhD holders and the labour market as presented in the Web of Science database

Abstract

The purpose of this paper is to use bibliometric analysis tools to evaluate valid papers on the relationship between PhD holders and the labour market. A review study was carried out of research papers on PhD holders and the labour market published between 1995 and 2024. The bibliometric analysis was carried out according to the following criteria: (1) Annual scientific production, (2) Most Relevant Sources, (3) Most Local Cited Sources (from Reference Lists), (4) Source Local Impact (h-Index), (5) Authors’ Local Impact, (6) Most Relevant Affiliations, (7) Corresponding Authors’ Countries, (8) Country Scientific Production, (9) Most Cited Countries, (10) Most Global Cited Documents, (11) Keyword Plus TreeMap, (12) Thematic Map: Strategic Diagram, (13) Social Structure: Collaboration Network (Countries), and (14) Countries' Collaboration World Map. Data analysis was carried out using R program and bibliometrix codes to produce a descriptive bibliometric study and a matrix table. The results show that the number of studies in the field of PhD holders and the labour market has continued to increase since 2001. There is interest in this area from many researchers, journals, countries and institutions, and both theoretical and experimental studies have been carried out. The studies generally focus on the labour market and job satisfaction of PhD holders through different research models.
