Innovation intensity and skills in firms across five European countries

This study attempts to establish the importance of specific formally achieved higher skills for the innovation intensity in firms across a group of European countries. Innovation expenditures are calculated as the ratio to turnover and the main explanatory variable is the proportion of highly skilled employees (tertiary education in ICT-oriented or other fields). The analysis employs official data on innovation activities (Community Innovation Survey) in firms for the period 2004–2010, linked to registers on education and businesses as well as to the Structural Business Statistics including 34,000 observations. Estimation results show a strong significantly positive relationship between the innovation intensity and the proportion of highly ICT skilled employees. Higher skills outside the field of ICT are also important for the innovation activities. Control variables reveal that the innovation intensity significantly increases with joint national and EU funding while the role of firm age varies. The significant and negative link to firm size reveals a lack of advantages of scale, a finding possibly related to the use of a comprehensive measure of innovation activities. There are also indications that industry affiliation is essential for the innovation intensity.
