A propos de l'hétérogénéité des formes organisationnelles de l'économie sociale : isomorphisme versus écologie des organisations en économie sociale

This article addresses the problem of the diversity of social economy organizational forms. Two theoretical approaches (organizational ecology and neo‐institutionalism approach focusing on institutional isomorphism) establish the main forces and determinants of these organizational forms. With data from a survey on Montreal social economy, we use diversified methods (discriminant analysis and latent class analysis) to test these two concurrent theories. As a conclusion, we discuss the established stylized facts. Our results are supportive of the organizational ecology approach, while calling for new empirical investigations.
