An analysis of the impact of investments on economic growth is conducted with a focus on Kazakhstan and foreign countries, identifying key approaches by which investments contribute to economic development in these countries. In the course of the study, the ratio of investment growth rates and GDP of the studied countries was analyzed, as a result of which the investment growth coefficient was calculated. The key factors that promote and deter investment are identified, as well as trends in comparison with other countries. The analysis of capital productivity was carried out by measuring GDP growth per unit of capital, which made it possible to assess the effectiveness of investment use. The results show that the predominance of investment growth rates over GDP growth rates in the Republic of Kazakhstan indicates an extensive type of economic development, which requires additional attention to improving the efficiency and sustainability of growth.
