The relevance of knowledge assets as fundamental strategic factors of business success has been widely recognised in today’s competitive scenario. This contribution analyzes “Collaboration agreements between administrations and citizens for the commons care”, a regulatory instrument for the implementation of the horizontal subsidiarity principle of the Italian Constitution. More than 250 municipalities developed this kind of regulations and nine Regions have approved analogous legislations. The heterogeneity of the local agencies, in terms of demographic and territorial breadth and their distribution on the national, regional, inland and mountain areas, are symptoms of a widespread interest in experimenting these new governance paradigms based on civic participation: from “governing for” to “governing with”. Therefore, this paper analyses territorial agreements in nine cities and explores the presence in these administrative processes of two functions that can characterize the capacity of modification and adaptation of the administrative structure: communication and evaluation.
