Beyond compliance: evaluating the governance capacity of public digital platforms in sustainable supply chains

This article examines how national digital platforms support the governance of sustainable and resilient public service supply chains. While digital infrastructures are central to procurement and investment planning, their role in enabling value co-creation and policy integration remains underexplored. Drawing on Public Service Logic, Public Service Supply Chain Management, and Procurement 4.0, the study analyzes five Italian platforms ANAC, OpenCUP, MePA, Italia Domani, and ReGiS through an eight-indicator evaluative framework. Based on document analysis and maturity modeling, results reveal divergent levels of interoperability, traceability, and strategic alignment. ReGiS shows high technical maturity but limited transparency; Italia Domani aligns with policy goals but lacks operational integration. Overall, platforms exhibit a procedural focus with limited systemic coordination. The findings highlight the persistence of compliance-driven digitalization and call for modular governance, citizen-oriented design, and predictive data ecosystems. This study contributes to understanding how digital infrastructures shape public value through supply chain reform.
