Nonprofit Sector Size and the Breadth of Local Government Climate Actions: Exploring the Moderating Role of Collaboration

Existing studies often use the association between sector sizes to test the supplementary and complementary models of government–nonprofit relations, assuming that one mode of government–nonprofit relations dominates a policy subsector. We challenge this assumption and propose that the relationship between nonprofit sector size and the breadth of local government policy actions depends on their level of collaboration. Situated in the context of urban climate governance and drawing information from a national survey of U.S. local government climate actions, we test this modified model and find a statistically significant moderation effect of collaboration. However, contrary to our proposed hypotheses, our findings suggest that a positive association between the number of environmental nonprofits and governmental climate actions exists when the level of government–nonprofit collaboration is low to moderate. We posit that the adversarial lens of government–nonprofit relations and the cost of collaboration are key to understanding these surprising findings.
