Abstract

We develop composite indices to assess regional digitalization at the NUTS 2 level in Europe. Building on the structure of the Digital Economy and Society Index, a first baseline index is created using Principal Component Analysis. The framework is extended through Geographically Weighted Principal Component Analysis and spatial filtering to account for spatial heterogeneity and dependence. The introduced approach distinguishes between regions benefiting from digital spillovers and those limited by geographic isolation. We therefore add on a method to classify spatial winners and losers based on the regional digital performance. This tool can be used to assess territorial disparities and design local policies for digitalization.
