As a driver of competitiveness, digitalisation is central to Europe’s economic agenda, yet adoption patterns remain heterogeneous, particularly between large firms and Small and Medium-sized Enterprises (SMEs). This thesis explores the micro-level associations between Information and Communication Technology (ICT) adoption and productivity in Italian enterprises, measured through value added per employee, thereby addressing a gap in the literature, which is often limited to macro indicators or single-technology studies. The analysis integrates three official Istat 2022–2023 datasets — the ICT Survey, the Structural Business Statistics (SBS) Frame, and the Statistical Register of Enterprise Groups — into a unified cross-sectional framework. Methodologically, Multiple Correspondence Analysis (MCA) and Exploratory Factor Analysis (EFA) are applied.
