Abstract

This study employs cluster analysis to examine how sustainable supply chain (SSC) practices influence performance outcomes addressing the fragmented understanding in prior reviews. Based on 78 peer-reviewed articles published between 2014 and 2021 the analysis investigates how different practices relate to performance dimensions. The two-step cluster analysis yielded two configurations: Cluster 1 linked environmental practices to positive economic outcomes while Cluster 2 linked social practices to positive economic outcomes. Although clustering quality was modest thematic analysis extended these findings by revealing broader but uneven associations. Environmental practices such as eco-design and cleaner production consistently supported both economic and environmental performance while reverse logistics and green procurement produced more variable effects. Social practices produced more fragmented effects: supplier development sometimes enhanced efficiency but labour rights and community initiatives were tied more to legitimacy and reputation than to measurable economic gains. Operational practices also surfaced in Cluster 2 contributing primarily to operational and social outcomes. These results highlight the uneven maturity of SSCM research: environmental practices are more consistently theorized and empirically validated whereas social and operational practices remain less systematic and context-dependent. The study further clarifies how theoretical frameworks map onto these findings with capability-oriented lenses (RBV, NRBV, dynamic capabilities) explaining internal resource advantages and adoption-oriented lenses (Institutional, Stakeholder, Legitimacy) capturing external pressures and legitimacy concerns. By moving beyond descriptive reviews to provide a cluster-based and thematic synthesis this study deepens theoretical understanding and offers actionable insights for scholars, practitioners and policymakers seeking to advance sustainable supply chain management.
