Public service is the production of goods and services that are undertaken by the state to meet the social needs, immune from certain principles of the market’s operating principles. Towards the end of 1980s, a significant change in the concept of public administration has been entered into the process of public administration, which has a hierarchical and bureaucratic structure, has changed to a flexible and market-based direction due to the economic and social conditions of the period. In recent years, as a general tendency, it is observed that Public Private Partnerships (PPP) are increasingly located in the field of public goods and services. Countries apply various PPP models according to their needs. The PPP is a contract-based relationship with the private sector to provide financing for the private sector, to establish infrastructure facilities, to undertake maintenance and management, to provide some core and ancillary services. Infrastructure investments and public services are made, financed and operated by the private sector,, and the contract is eventually transferred to the public sector with certain characteristics. The history of PPP models in Turkey has developed in a different way compared to the other countries in Europe. In the last 30 years, dozens of projects, especially in electricity generation and distribution, health, airport, port and highway areas have been realized with this model.
