Empirical findings show that investments in information-telecommunication technologies (ICT) contribute significantly to the economic growth at macro and micro level. At the same time, we witness a slowdown in ICT investment in Slovenia, in spite of the fact that there still exists a gap in the level of ICT use in comparison to more developed countries. The article presents main findings of different approaches to measuring the impact of ICT in Slovenian firms. A positive impact of ICT is found primarily with intensive ICT users, which should stimulate all firms to further invest in the area. Since on the contrary a slow-down in investments in ICT is occurring, we claim that Slovenian firms lack a coherent long-term eStrategy. Such behaviour may result in under-exploitation of the potential that ICT can have for productivity growth and competitiveness of companies.
