This study investigates the emergence of a collection of diverse organizations designed to enable and govern infrastructure public–private partnerships (PPPs). The authors use the concept of organizational fields as a theoretical lens to investigate this panoply of organizations in three international contexts: British Columbia (Canada), Victoria (Australia), and South Africa. They observe a similar set of actors in each of these “PPP-enabling fields” but detect significant variation in the actor characteristics and the way that they are arranged on different projects. They theorize on a number of PPP-enabling fields aspects, including typical project arrangements, predominant field intermediaries, and salient institutional logics.
