Green synergy: Integrating green human resource management and green supply chain management for sustainable performance in the Thai hospitality industry

Human resource management and supply chain management literature have largely evolved in parallel, with insufficient attention paid to the interrelationships between them in driving sustainable performance. Drawing on natural-resource-based view, this study aims to determine the synergic effect of green human resource management (GHRM) practices and green supply chain management (GSCM) practices on sustainable performance. Additionally, the moderating roles of supply chain traceability and supply chain eco-centricity are examined. Data was collected using a time-lagged survey from 363 managers and employees working in green hotels in Thailand. The findings revealed that both GHRM practices and external GSCM practices positively influenced sustainable performance. Moreover, internal GSCM practices mediated the link between GHRM practices and external GSCM practices, and supply chain traceability and supply chain eco-centricity moderated the positive relationship between external GSCM practices and sustainable performance. Theoretical contributions and practical implications are discussed.
