This study analyzes the impact of Information and Communication Technologies (ICT) on the operational efficiency of Chilean Small and Medium Enterprises (SMEs), aiming to identify the most relevant digital tools to support their development and guide public policy.

We used microdata from the Fifth Longitudinal Survey of Enterprises (ELE5). An ANOVA was applied to assess differences in ICT adoption across economic sectors, and a factorial analysis was conducted to identify the most influential technological dimensions.

Four key ICT dimensions—transactional, informational, infrastructure, and strategic—were found to significantly influence SME operations. The results highlight that ICT adoption varies notably across sectors, suggesting that its impact is not uniform.
