This paper attempts to at least partially redress a paucity of current literature on the joint analysis of inter and intra firm diffusion of innovations within as well as across countries. In particular, by using two datasets derived from independent countryspecific surveys, it undertakes an international comparison of inter and intra firm diffusion of ICT use in the UK and Switzerland. This allows one to address many of the problems that have prevented general conclusions on the drivers of inter and intra firm ICT adoption decisions. An encompassing model is proposed which gives quite satisfactory results for both countries. It is found that inter and intra firm ICT adoption decisions are driven by different factors, confirming the findings of Battisti and Stoneman (2003, 2005) and Hollenstein and Woerter (2004) that first use and intensification of use represent independent choices. The study also suggests that significant differences exist between the UK and Switzerland, probably as a result of their differing diffusion stages. Besides, the importance of new organisational and managerial practices as drivers of diffusion stressed by recent theoretical and empirical work is supported for both countries. Overall the findings suggest that comparative research is a promising way to identify robust relationships and should be explored further.
