One of the objectives of the European Commission for 2014-2020 is to establish " Research and Innovation Strategies for the Smart Specialization " (RIS3). The originality of RIS3 is the " bottom-up " identification of regional priorities especially through the " Entrepreneurial Discovery " (ED) process. The Collaborative Business Models (CBM) approach has probably a role to play within this process as a suitable strategic tool to set up regional " value networks ". However, the preparatory stage of CBM and especially the identification and the matching processes among potential RE partners is often not addressed. This work is based on the need to support the discovering and the matching processes between " regional entrepreneurs " (companies, research , consulting, association, public authorities…) in order to improve the efficacy of CBM and RIS3. In this paper, we propose a review of the state of the art concerning the different dimensions linked to the matching processes.
