The share of R&D expenditures is different across the EU Member States, ranging from 3.25 % of GDP to 0.44 % of GDP in 2016. The convergence (σ –convergence, β-convergence) of R&D expenditures in the EU countries has not been confirmed in period 2004 and 2017. A significant relationship was found between R&D and labour productivity only in some countries. Many factors influence this relationship as a time lag or R&D orientation.
