Résumé
Entrepreneurial ecosystems see emerge new organizational forms, including corporate accelerators, which we refer to as micro-ecosystems and that we can define as a localized system, driven by an actor or group of actors that can impel a dynamic of innovation and entrepreneurship open and interacting with the entrepreneurial ecosystem. However, the literature reveals that little attention has been given to the actors and how they act and our understanding on corporate accelerators remains poorly developed. This paper aims for understand the process of emergence and institutionalization of corporate accelerators from a multi-level approach, from political, technical and cultural institutional work. A qualitative study was conducted on a corporate accelerator created by the initiative of an established company in the banking sector. The results reveal that the emergence and institutionalization process of corporate accelerator is the result of institutional work at macro, meso and micro level and that levels are in constant interaction.
