Sustainable purchasing and supply management: a structured literature review of definitions and measures at the dyad, chain and network levels

Abstract

PurposeThis paper provides a structured literature review of sustainability in purchasing and supply management, moving beyond the traditional environmental and social sustainability. The paper reviews the concept of sustainability at three levels of inter‐organizational analysis – i.e. dyad, supply chain and network. The paper distils the nature and scope of existing research and synthesizes measures used to research sustainability across organizational boundaries.Design/methodology/approachThis literature review systematically analyzes existing literature. In particular, the review focuses on definitions and measures of sustainable purchasing and supply management to obtain an accurate view of current research.FindingsThis paper uncovers two distinct trends in the type of research carried out. First, internal or dyadic issues are in focus and second, a tendency to deal with environmental, as opposed to social, sustainability. Despite the need to look beyond the dyad given the risks associated with the extended network, few studies do so in any of the sustainability dimensions.Research limitations/implicationsThis review is limited by the method employed focusing on definitions and measures. Although the review considers supply chain and network research, it does so purely from a purchasing perspective, thus excluding issues such as logistics and transport.Practical implicationsThe paper identifies areas open to future research and provides practical insights into how sustainable purchasing and supply are measured. It also synthesizes existing measures of sustainability at different levels and organizes these into a taxonomy.Originality/valueThe paper examines studies across multiple levels of analysis and integrates multiple fields of knowledge to show how research on sustainability in purchasing and supply is structured.
