The study deals with the issue of the concession of state-owned assets, a typical institution of Administrative Law, in order to verify its topicality, also in the light of the parallel evolution of the legal model of “property” based on the rules of the Civil Code, which is reflected in the public nature of the assets reserved to the Public Administration and their management. The concession power, in allowing the particular use of state-owned property by private subjects, must be referred to the present context, in order to highlight the growing importance of the role of the Public Administration, both in relations with and between private individuals, and in terms of correct assessment of the profitability of the choice made by it, pursuant to public accounting.
