This paper investigates empirically the competing predictions of three perspectives on the determinants of organizational isomorphism-population ecology, institutionalization, and strategic choice-through a collective strategy framework, which categorizes organizations in an interorganizational field by their relationships with one another. The methodological approach, based on a network analysis of multiple organizational relations in a population of voluntary social service organizations, operationalizes the collective strategy typology and links homogeneity among organizations to their location in the organizational field. The results of the investigation offer strongest support for a strategic choice perspective and suggest that the environment is not highly deterministic in shaping organizational characteristics.'
