This could be a powerful research work given the focus of the discourse on education and economic growth, however, to be able to understand the concept and identify the relevant intermediate variables to be used for your study I suggest you read the works of Prof. Simplice Asongu. He has more publications related to the current subject. Thank you!
Human Capital Accumulation: Education enhances human capital by imparting knowledge, skills, and abilities to individuals. A more educated workforce is often more productive, innovative, and adaptable, leading to higher economic output and growth.
Labor Force Participation: Education increases labor force participation rates by equipping individuals with the qualifications and skills required for employment. Higher levels of education tend to correlate with higher employment rates, thereby contributing to economic growth through increased workforce participation.
Productivity: Education improves labor productivity by enhancing cognitive abilities, problem-solving skills, and technical expertise. Educated workers are often more efficient and effective in their tasks, leading to higher levels of output per worker and overall productivity gains, which are essential drivers of economic growth.
Innovation and Technological Progress: Education fosters innovation and technological progress by cultivating critical thinking, creativity, and research skills. Well-educated individuals are more likely to engage in research and development activities, leading to the creation and adoption of new technologies and processes that drive economic growth.
Entrepreneurship: Education fosters entrepreneurship by providing individuals with the knowledge, skills, and confidence to start and manage businesses. Entrepreneurial activity contributes to economic growth through the creation of new products, services, and employment opportunities, as well as the expansion of markets and industries.
Income Distribution: Education can influence income distribution by reducing inequality and poverty. Access to quality education empowers individuals from disadvantaged backgrounds, enabling them to secure higher-paying jobs and improve their socioeconomic status. A more equitable distribution of income can stimulate consumer spending and investment, driving economic growth.
The association between education and economic growth stems from the benefits of human capital within the economy. Educated individuals, especially those with higher levels of education, contribute significantly to the economic sector. They possess skills, familiarity with technology, innovative ideas, open-mindedness, and are more readily employable compared to their less educated counterparts. Furthermore, educated individuals tend to earn higher wages, leading to increased tax contributions to governments. On the health front, educated people tend to lead longer and healthier lives, further bolstering economic productivity and well-being.
What is learnt from using Smooth Transition Regression models for the education-economic growth link is that the educational level of the population can be understood as a source of nonlinearities in the economic activity of a country (and of a region). Thus, depending on national and regional educational levels, economic growth behaves differently.

Human capital accumulation undoubtedly fosters labor force participation, productivity, and so on. But an increased labour supply (in quality and quantity) needs to be matched by a similar increase in labour demand. If this does not happen, as in Italy in the last twenty years, the result is a substantial emigration of young skilled people (mainly towards other EU countries).
“Workers who adapt well to technological changes achieve higher productivity. Therefore, if labor productivity can be increased, higher economic growth can be achieved even if the labor force is fixed. Highly capable workers who adapt well to such technological changes are nurtured through education. Thus, the mediating variable between education and economic growth can be said to be technological change. Examples of technological change include the enhancement of computer performance, the advancement of artificial intelligence technology, the sophistication of robotics technology, and the improvement of mobility technology.”
