''The dynamics of international patents production: A panel smooth transition regression approach''
( 2024, Vol. 44 No.1 )
 
 
The main aim of this paper is to evaluate the major determinants of country-level production of international patents. We investigate a nonlinear relationship between ICTs' components and patents, using a PSTAR model based on the national innovative capacity framework. More particularly, we incorporate a wide set of policy and economic factors explaining cross-countries difference in the intensity of innovation. Our empirical results confirm the finding of R. Inglesi-Lotz and al (2018) whereby the Organization for Economic Co-operation and Development (OECD) and BRICS countries should not exceed the optimal levels of 1.688 and 0.975 (in % of GDP), respectively to engage in patenting and to get involved in the innovation system. The major explanations of our finding are the particular devoting of R&D budget to various sectors and the re-allocation of R&D resources in other productive sectors.
