The social capital phenomenon is considered as the missing link of growth by recent studies. Attention has been drawn to the determinant of institutional factors, especially a stable democratic structure, for the occurrence of an impact of social capital on growth. In this regard, our study, covering 138 countries over the period 2009-2018, consists of two research questions. Firstly, “Does the economic growth performance of countries depend on accumulation of social capital as well as the physical and human capital accumulation highlighted by the theory?” Secondly, “Does the impact of social capital on growth change depending on the democratization level of the countries?” Linear panel data analysis was employed to examine the first question and the panel threshold method proposed by Hansen (1999) was utilized for the second research question. This nonlinear approach constitutes the original value of our study. Our analysis results indicate that, in countries where the democratization level is above a certain level, social capital has a determining impact on growth. In this framework, our findings indicate that the establishment and maintenance of democratic structure is one of the substantial policy focuses in the process of social capital-led growth.
