Abstract
The article focuses on the formation and development of public-private partnership (PPP) in Kazakhstan, exploring its institutional mechanisms and impact on sustainable infrastructure development. The main objective of the study is to analyze the stages of PPP formation, the legal framework, and key projects, as well as to assess their contribution to the socio-economic development of the country. The paper examines the legal and economic aspects of PPP, its impact on attracting private investments, and improving the quality of infrastructure projects. The scientific and practical significance of the study lies in identifying trends and issues in the development of PPP in Kazakhstan and developing recommendations for improving implementation mechanisms. The article demonstrates how PPP contributes to achieving sustainable development goals, including the development of transport and social infrastructure, the introduction of energy-efficient technologies, and improving the quality of life of the population. The relevance of the study is determined by its focus on solving practical tasks related to improving the investment climate and reducing state budget expenditures. The recommendations presented can be useful for both government agencies and private investors to enhance the effectiveness of infrastructure project implementation. The results obtained have practical significance for optimizing PPP mechanisms, which will strengthen Kazakhstan’s economic resilience, attract additional investments, and improve infrastructure quality.
