This paper investigates the effects of R&D disparity on economic growth in 39 countries from 1990 to 2017. R&D disparity refers to the level of inequality in R&D expenditures distributed within R&D financing and performing sectors and types of research, measured by Gini Index. Using a fixed effect regression analysis, we found that the disparity of R&D expenditures negatively affects countries’ GDP per capita and its impacts vary by sectors, types of research as well as countries’ economic status. The negative impact of the disparity in R&D financing sector is twice as greater in the advanced countries than in the less advanced countries. On the other hand, the negative impact of the disparity in R&D performing sectors appears more severe in the less advanced countries than in the more advanced countries. Also, the disparity by types of R&D activities has a greater impact in the advanced countries than in the less advanced countries. Our findings suggest that R&D should be promoted more evenly across the sectors and types of research, and countries need different R&D investment strategies depending on their economic status.
Abstract
This paper investigates the effects of R&D disparity on economic growth in 39 countries from 1990 to 2017. R&D disparity refers to the level of inequality in R&D expenditures distributed within R&D financing and performing sectors and types of research, measured by Gini Index. Using a fixed effect regression analysis, we found that the disparity of R&D expenditures negatively affects countries’ GDP per capita and its impacts vary by sectors, types of research as well as countries’ economic status. The negative impact of the disparity in R&D financing sector is twice as greater in the advanced countries than in the less advanced countries. On the other hand, the negative impact of the disparity in R&D performing sectors appears more severe in the less advanced countries than in the more advanced countries. Also, the disparity by types of R&D activities has a greater impact in the advanced countries than in the less advanced countries. Our findings suggest that R&D should be promoted more evenly across the sectors and types of research, and countries need different R&D investment strategies depending on their economic status.
