Public procurement, now widely recognized as one of the vital components of public administration (Basheka, 2013 Bröchner, 2010 Fagan, 1999 Schrouder, 2010 Thai, 2001), is linked to economic growth, competition enhancement, policy achievement, and innovation promotion (Flynn & Davis, 2014 Geroski, 2006 Grega & Nemec, 2015 Wan, 2014). This study contributes to the public procurement literature and serves as a basis for further research and policy making in the Greek procurement sector. Future research should address these limitations and explore the effects of market concentration on CPV codes in greater depth. While this study provides valuable information, limitations including variations in data availability and potential inaccuracies in recorded information exist. Given that the concentration of contract awards raises competition, fairness and transparency concerns, the implications of the findings are important for policymakers, regulators and stakeholders involved in the Greek public procurement market. These differences highlight the heterogeneity in the Greek public procurement market, as well as the need for sector-specific policy interventions. The analysis of degree distributions between sub-networks based on CPV groups indicates variations in market structures between sectors. In contrast, some CPV groups demonstrate a more balanced distribution of contracts among EOs, suggesting a healthier competitive environment. The findings reveal the presence of market concentration, where a few EOs receive a disproportionate share of contracts within certain CPV groups which suggests potential market dominance and lack of competition. By examining degree distribution curves and identifying dominant economic operators, we gain valuable insights into market dynamics and competition in Greece. This study uses network theory to analyze the structure and concentration of the Greek public procurement market, focusing on the relationships between Contracting Authorities (CAs) and Economic Operators (EOs) within different Common Procurement Vocabulary (CPV) groups. ![]()
