Abstract
The article presents a comprehensive analysis of the current state and development of airport infrastructure in the Republic of Kazakhstan, which is a key element of the national transport system and an important factor for the country's economic growth. Airports provide not only domestic and international mobility but also contribute to the development of tourism, international trade, and Kazakhstan's integration into the global transport network. In recent years, passenger and cargo air traffic volumes have increased significantly, creating higher demands for airport infrastructure modernization and implementation of international safety standards, including ICAO and IATA. The aim of the study is to assess the current state of Kazakhstan's airport infrastructure, identify problem areas, and develop strategic directions for its further development. The research objectives include examining the technical condition of runways and terminals, analyzing airport management efficiency, conducting comparative analysis with international practices, determining modernization priorities, and developing recommendations to enhance the sector's competitiveness. The results revealed a high level of wear in regional airport infrastructure, insufficient modern equipment, a significant concentration of passenger flow in three major aviation hubs, and low private investment attraction. The analysis also highlighted the need for digital technology integration, management optimization, and implementation of public-private partnership mechanisms. Sustainable development of Kazakhstan's airport network is achievable through comprehensive infrastructure modernization, implementation of international safety standards, digitalization of processes, and investment stimulation, which will improve passenger service quality, ensure effective management of the aviation sector, and strengthen the country's position as a transport hub between Europe and Asia.
