For the last two decades many countries have developed Public-Private Partnership (PPP) and founded some management systems. Each of those countries has its own model of PPP taking into account specific aims and goals they pursue and priorities of their economic policy. Legislative and regulatory frameworks, administrative structures and functions of government authorities that are inherent in a given country, exert a great influence upon those models. In regard to this, the level of development of market economy and institutions of civil society and of legal culture (both officials and businessmen) is of great importance. The  article is devoted to issues of PPP governance mostly in developed countries. The role of governing authorities in PPP implementation and their standing in the government structure have been disclosed and analysed, as well as their functions and outcome of their activities.
