<p>Corruption evolves over time. This paper investigates why and how this evolution happens. The analysis has employed a combination of qualitative network and document analysis to explore the configuration of corruption in two moments in Italy and the changes that have happened in between them. The findings have disclosed that a higher efficiency of the activities of the criminal-justice chain, the transformation of the critical actors, and the reform of legal frameworks and governance systems have been critical in determining the evolution of corruption. The added value of the research lies in its ability to examine these transformative mechanisms within a conceptual framework that keeps together the fact that corruption is networked and that networks evolve over time.</p>
