Human capital as the most important factor of economic growth and development of countries, in addition to a direct effect on production, also effects on other factors of production and it is also affected by them. Therefore, the present study endeavors to investigate the interaction between human capital and capital accumulation in selected countries of the Mena by using a system of simultaneous equations for the period (1996-2019). The results show that human capital and capital accumulation in the studied countries have a positive and reciprocal effect on each other and increasing inflation as one of the macroeconomic variables reduces the accumulation of capital through the expansion of economic uncertainty. Also, earning income through the sale of natural resources, which is one of the prominent features in the studied countries, has a negative and significant effect on the accumulation of capital and human capital, and finally increase GDP per capita without selling natural resources has a positive and significant effect on human capital in the studied countries.
