4. Analytical Framework
Based on the literature reviewed, the national system of innovation basically consists of three segments: universities, governments, and the businesses, with each segment interacting with the others, while at the same time playing their individual roles. The figure below is a simple illustration of how these three key players come to form the NIS. It is also important to note that NIS is a complex conglomerate of interacting independent parties that has to do with the ability to plan and integrate policies and institutions. The Universities play the role of undertaking basic science and technology research; educate scientists and technologists needed by governments and business. Governments in turn play the role …show more content…

The essential data set for the selected countries were sourced from the International Financial Statistics and the World Bank data base 2014. The selection of the variables was however limited to data availability and the common characteristics of the economies involved in the present study.
5.2 Empirical Model Specification and Estimation Techniques
Following an endogenous growth framework, the study specifies a model that best captures the effect of national innovation system on economic growth. Given the growing empirical evidences supporting the positive effect of innovation on economic growth (Hulya Ulku, 2007; Yanrui Wu, 2012) we control for other factors that influences long run growth and generalize the specification of a growth equation that accounts for the effects of national innovation system on economic growth. Thus, in deriving our empirical model for estimating this relationship for BRICS, we posit that: ln(Yit) = α + β1 ln(UEit)+ β2 ln(RDit) + β3 ln(TMit) + 훌1 ln(PTit) + 훌2 ln(SPit) + 훌3 ln(SJPit) + ɳi +ԑit (1)
Where the independent variables are defined as follows:
UE = University enrolment rate as a proy for university
RD = Government Research and Development Expenditure,
TM =
