Recent trends in productivity growth and differences in productivity levels between countries have been increasingly associated with widespread differences between firms within sectors, both in technology use and in firm performance.

The SEEK project "Digitalisation and Heterogeneity" aims to provide a comprehensive overview of the heterogeneity in the diffusion of digital technologies and its impact on firm performance. The analyses focus on the question of how heterogeneous industries and countries are with regard to their investments in digitalisation and how this is linked to heterogeneity in firm success. In particular, the reasons for the observed heterogeneity within industries will be analysed. In contrast to earlier studies, the connection between the heterogeneity of digitalisation and the heterogeneity in the innovation performance and productivity of firms within sectors will be explicitly examined.
