The role of purchasing and supply management in diffusing sustainability in supply networks: A systematic literature review

Abstract

One of the most difficult supply network challenges facing companies today is how to diffuse sustainability not only among their direct (first-tier) suppliers but also throughout their supply networks. Although a growing body of research has been dedicated to addressing this challenge, the role of purchasing and supply management (PSM) in sustainable supply network development remains underexplored. In this paper, we present a systematic review of the literature on the role of PSM in the diffusion of sustainability in supply networks. We analysed 133 peer-reviewed papers published in 21 journals in the field of PSM. We scrutinized the theories, methods and levels of analysis used in sustainable PSM research, classified the practices for diffusing sustainability in supply networks and identified the role of PSM in the diffusion of sustainability. Accordingly, we put forward a set of propositions that link diffusion practices—and the role of PSM in these practices—with embedded and peripheral sustainability and suggest future research directions.
