Toward Innovation-Driven Competitiveness Across African Countries: An Analysis of Efficiency of R&D Expenditures

The main goal of this paper is to determine whether R&D funds are used efficiently in African countries. The innovativeness of a country's economy is nowadays one of the key factors stimulating the economic growth and competitiveness. Becoming more innovative is important in particular for developing countries, whose governments are developing national innovation strategies (NIS) and assuming a steady increase in research and development spending. Efficient innovation policies are creating conditions for enterprise development and the increase of competitiveness of the country. A calculation of R&D spending efficiency for selected African economies for the years 2009-2017 was carried out using Data Envelopment Analysis methodology, which allows the evaluation of input-output efficiency. Public and private spending on R&D as % of GDP was the selected inputs indicator. The model examines three output indicators: the number of patent applications (per million inhabitants), high-technology exports (% of export), and number of technical and scientific journal articles (per million inhabitants). Among the analyzed countries, those on the efficiency frontier regarding the use of CRS methodology are South Africa and Tunisia. According to VRS methodology, the most efficient nations are South Africa, Tunisia, and Madagascar. The performed analysis has not confirmed our hypothesis regarding the non-proportional relation between higher R&D spending and innovation outputs. Considering limited innovation capacities across African countries, it appears to be reasonable to increase R&D expenditures gradually to achieve better results on the path toward innovationdriven growth and development.
