The role of R/D expenditure: a critical comparison of the two (R&S and CIS) sources of data

The paper explores the relation between two data sources (R&D and CIS surveys) in the aim of better representing the roles of R/D activity in relation with innovation processes. This paper starts with controlling the relation between the R/D expenditure in the two surveys (R&D and CIS) for a same group of firms and for the same year (2000) and deals with the question of how much we know at present of the different components of the industrial R/D activity and how we can use the frame of the two surveys for arriving to gain this knowledge. The final aim is that of getting finest grained indicators for studies on the impact of industrial investment on R/D.
