One of the features of the legal regulation quality in the field of PPP is the interest of business in the implementation of infrastructure projects using this mechanism. At the initial stage of the PPP development, this interest is expressed in the active participation of business in competitions for the implementation of PPP projects and / or in the preparation of unsolicited proposals (USPs). At the next stage, in the number of successful PPP projects. In conditions when the public authorities do not make efforts to structure PPP projects, it is business who takes the initiative by starting the preparation and submission of unsolicited proposals. The attitude to such proposals by the public authorities and the expert community is very different. In a number of countries, including Ukraine, there are many discussions about the expediency of USPs and the approaches that should be used when considering them. This article presents an analysis of various points of view regarding unsolicited proposals; an assessment of the advantages and disadvantages of USPs compared with the proposals prepared on the initiative of public authorities; the author’s observations regarding the potential of using this mechanism to achieve the public interest and recommendations on how some of the problems existing in this area could be resolved.
