The public-private partnership is an instrument by which the modern state can manage with maximum efficiency the public patrimony and the public services. The essence of the public-private partnership (PPP), consists in the establishment, under different forms, between the public authorities and the business environment, in order to ensure the financing, construction, renovation and maintenance of an infrastructure, or, the provision of a service of public interest. The good practices of the states with experience in this field were also adopted by the Republic of Moldova. The concept of PPP appeared in the legislation of the Republic of Moldova after gaining independence (1991), being enshrined, directly or indirectly, in multiple normative acts, including, in a special law. According to the legislation in force, the public-private partnership aims to carry out projects of public interest, to increase the efficiency and quality of services, public works and other activities of public interest and the efficient use of public heritage and public money. Although, the existence and quality of the normative regulations are fundamental and have a special importance for good activity of the public authorities, however, the mechanism for the achievement of the PPP does not work automatically, automatically, or, as a result of the adoption of the corresponding normative regulations. As a result, in the Republic of Moldova, the implementation of these legal regulations has encountered multiple difficulties, so that, so far, we have no examples (practices) that PPP has succeeded. In order to successfully achieve the PPP, both the capacity of the public authorities to clearly define that part of the public heritage and services that it can manage through state (public) economic institutions and entities, of that part, is necessary. It will train the private partners as well as the professional training of the public officials and all the actors involved in the PPP, who must know, in details, the basic rules and the principles of functioning of such a partnership.
