Determinants of R&D on European high technology industry: panel data evidence


Purpose
As high-tech industries are the main responsible for research and development (R&D), the purpose of this paper is to investigate some of the possible determinants of R&D investment in this type of industry.


Design/methodology/approach
The analysis is based on a sample of European high-tech industries represented both by countries of civil law origin and common law origin. The authors used data from 155 high-tech firms in the period between 2011 and 2016. The sample was collected from Amadeus database. The panel data methodology was used to test the dependence of R&D expenses ratio according to different variables. Specifically, the authors have used the generalized method of moments (GMM) estimation method.


Findings
The results point out that there are differences in the explanation of the R&D ratio depending on whether the authors are dealing with countries of civil legal origin or common legal origin. The evidence also suggests that the intangible assets, contrary to the expect result, have a negative influence on R&D. Probably in this recovery time, as de global financial crisis and the sovereign debt crisis for Eurozone countries, the high-tech firms are using their intangible assets to create value and not for more investments in R&D. Companies are not renewing their asset stocks.


Originality/value
As high-tech companies are traditionally rich in R&D, this research can contribute with additional pieces to the knowledge of the factors that contribute to this. Thereby, this study may be interesting for managers, investors and civil society. This study adds value as it is unique in addressing this topic on this new dimension, with respect to the sample and indicators presented.
