Abstract
The study of PPP as a factor in the sustainable development of Kazakhstan’s economy is a relevant task that helps identify effective mechanisms for the country’s growth. This article aims to substantiate the impact of PPP on sustainable development by establishing its link to achieving the SDGs, analyzing global PPP practices, identifying methods for evaluating PPP effectiveness, and presenting promising application areas in Kazakhstan. The scientific significance lies in identifying the main effects of PPP (economic, social, environmental, and institutional) and determining the most informative tools for assessing its effectiveness, such as key performance indicators (KPIs), benchmarking, expert surveys, and satisfaction analysis. The study outlines how PPPcontributes to national sustainable development by integrating public and private resources to solve key challenges. It also defines the potential of PPP to advance the UN Sustainable Development Goals in Kazakhstan. The practical value of the research is the applicability of the proposed assessment tools and strategies for engaging the private sector in addressing critical socio-economic issues. Examples provided in the article demonstrate how PPP increases efficiency and supports sustainability in areas such as infrastructure, education, healthcare, and ecology. It has been established that PPP holds significant potential for promoting Kazakhstan’s long-term growth. The article contributes to the theoretical understanding and practical application of PPP tools in the context of sustainable development, offering insights for improving national policy and fostering partnerships between the public and private sectors.
