Innovation intensity and skills in firms across five European countries

Abstract

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.

Employment effects of R&D and process innovation: evidence from small and medium-sized firms in emerging markets

“…Recall firm size is measured in natural logs. The finding about the impact of firm size can be seen as consistent withBeck et al (2005) where, using a sample of 54 nations, they find that small firms benefit the most from financial and institutional developments (also seeFalk and Hagsten (2021)). The negative sign on the size variable is consistent with the notion of a lack of scale economies.…”

On the trail of the intangible: a theoretical and empirical investigation of innovations and patents in Germany in the years 2006-2019

“…Urbaniec (2019) finds that innovation activities and competitiveness are necessarily interrelated: competitiveness spurs innovation intensity, but innovation intensity also enhances competitiveness. Many recent publications can be found which investigate the determinants of innovation intensity in cross-section or country studies (Falk & Hagsten, 2021;Thang et al, 2021). Goel and Zhang (2019) discover the possibility to hedge against political and economic uncertainties by innovating and, later on, patenting (Goel & Nelson, 2021).…”
