Investigating the Impacts of Green Procurement on Supply Chain Resilience Through Supply Chain Collaboration: The Moderating Role of Human Resource Practices

Green procurement acts as one of the key sustainable supply chain practices for firms, and supply chain resilience sets the basis for improving firms’ internal growth and competitiveness. However, scant research attention has been paid to exploring this relationship. Hence, this study developed a model and assessed the impact of green procurement on supply chain resilience through the intermediary role of supply chain collaboration. The study also assessed the extent to which human resource practices could moderate the relationship between green procurement and supply chain collaboration. With the aid of questionnaire administration, 695 responses were collected from various managers of manufacturing firms in Ghana. Findings from analysis using structural equation modeling as our analysis tool to estimate the direct and structural mediation showed that green procurement had a significant influence on both supply chain collaboration and supply chain resilience. Supply chain collaboration also had a significant influence on supply chain resilience. The mediation role of supply chain collaboration revealed a partial mediation between green procurement and supply chain resilience. The moderation impact of the three factors of human resource practices (training, empowerment, and reward) was examined using hierarchical regression analysis. It was revealed that all three factors of human resource practices chosen for this study moderated significantly in the relationship between green procurement and supply chain collaboration. The study offers some contributions to theory and practice in the main text and can be used for reference by academicians and managers.
