Instrumentation of "Entrepreneurial Discovery" processes in the framework of Research and Innovation Strategies for Intelligent Specialization (RIS3): proposal of a collaborative platform and a "matching" methodology between "Regional Entrepreneurs" to promote exchanges in the intermediate zones of the regional innovation system of New Aquitaine.

Summary Since 2014, the European Commission has been encouraging the regions of its member states to establish a new type of territorial development strategy that should encourage them to specialize in areas that are rooted in their territory in order to create original competitive advantages that are difficult to imitate: the "Research and Innovation Strategies for Intelligent Specialization" (RIS3). Since 2014, the RIS3 are also a condition for obtaining ERDF funds used to finance the development of these regions. But the main originality of the RIS3 lies in the fact that these processes of selection and prioritization of specializations, which are established at the global scale of regions according to a classic decision-making dynamic that goes "from the top down", must now be based on processes of identification of areas with high potential that must be conducted "from the bottom up" via a process of Entrepreneurial Discovery (ED) that should allow a maximum of "Regional Entrepreneurs" (RE) (of all sizes, statuses or sectors) to participate in the definition of the directions of their territory. However, there is a certain lack of methodological recommendations to concretely instrument these processes within the realities of each regional innovation system. This thesis therefore presents two software prototypes that we have developed to instrument these two-way mechanisms within the innovation system of New Aquitaine: (1) "WeKeyInnovation," a collaborative platform that should allow all BRs to share useful information for innovation, but also to lay the foundations of a real dynamic observatory to help the regional public authorities identify in real time the practices, needs and high-potential initiatives emanating from the actors in the field who evolve in the territory. (2) "DialoJ", an online matching tool based on the resolution of dialogical questions prior to events in order to help REs who intend to participate in them to clarify their expectations and to better visualize those of the other actors in order to facilitate the identification and matching processes with more adequate potential business partners as a preliminary step to any collaborative business approach.
