Résumé
The concept of an entrepreneurial ecosystem is an emerging but underdeveloped theoretical construct that aims to explain the evolution of the ecosystem. The ecosystem concept is composed by different layers such as sub-ecosystems which interact with each other. Nevertheless, the entrepreneurial ecosystem has been mainly studied at the national level, but has not yet been explored in depth at the level of a specific sub-ecosystem: the entrepreneurial support ecosystem. The goal of this study is to advance the emerging theoretical concept of entrepreneurial ecosystems by examining the entrepreneurial support ecosystem and the coopetitive dynamics of its members by focusing on business incubators as “keystone player” of this specific type of ecosystem.
