This paper examines empirically the factors that facilitate sustainable supply chain management, which involves the integration of environmental and social issues into conventional supply chain management processes. To build a theoretical model for this issue, the author adopted two previously disparate perspectives together: stakeholder theory and a resource-based view of the firm. Stakeholder pressure, a firm’s sustainability issues integration capability (SIIC), and expected sustainability benefits (ESB) were investigated as the antecedents of sustainable SCM. To test hypotheses, this study utilized structural equation modeling with data from 78 Korean firms. SIIC was found to significantly predict sustainable SCM; however, mixed results were found regarding the effects of stakeholder pressure and ESB on SIIC and sustainable SCM. This research represents one of the few survey-based studies which explore the factors that influence sustainable SCM with a dual consideration of external pressure and internal capabilities.
