À propos de l'hétérogénéité des formes organisationnelles de l'économie sociale

This paper 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 non-parametric (K-nearest neighbors discriminant analysis) and parametric (latent class analysis) methods to test these two concurrent theories. As a conclusion, we discuss the established stylized facts. Our results are supportive of the organizational ecology approach.
