Abstract
Digitalization and sustainability have fundamentally reshaped the purchasing and supply management (PSM) landscape. The nexus of these two topics defines a research frontier requiring new methodological, theoretical, and empirical development. This editorial provides an overview of the three papers in the special issue and explains how they fit within and contribute to a research landscape composed of five interconnected themes. These themes reflect continuing challenges and tensions for digital and sustainable PSM. The themes include Circular and Sustainable Business Models; Strategic Integration and Supply Chain Transformation; Platforms, Collaboration and Governance; Measurement, Transparency and Accountability; and Performance Implications for Sustainability. We reflect on ongoing methodological challenges and identify ways to advance established PSM methodologies. Our goal is to highlight insights from the special issue articles and identify topics that provide avenues for further research. We present a framework that invites the research community to engage with these themes, their tensions, and relevant theoretical perspectives. Such investigation can help the field understand and guide the implications of this nexus for ecological sustainability, social justice, and economic value creation within and beyond PSM.
