Abstract
This study examines the effectiveness of the legal regulation of public procurement in the EU, focusing on the challenges posed by the digital transformation of the economy. The research highlights key legal issues, including non-compliance with competitive procedures, insufficient cross-border market integration, and inadequate transparency in procurement processes. Particular attention is given to the implementation of the Directives 2014/24/EU and 2014/25/EU within the Member States' national legislation. The study identifies critical legal shortcomings, such as significant reliance on non-competitive procurement, low levels of cross-border contracting, and widespread gaps in reporting essential procurement data. These issues undermine the principles of transparency, competition, and equal access enshrined in EU law. The legal and institutional barriers to achieving sustainability goals, such as the EU’s green procurement target of 75% by 2030, are also addressed. To resolve these challenges, the research proposes a legal framework for the digital transformation of public procurement. This includes adopting unified standards for electronic documentation and creating integrated cross-border procurement platforms to ensure compliance with EU principles and foster market integration. The findings and proposed measures offer valuable insights for improving procurement systems both within the EU and in other jurisdictions undergoing economic integration.
