Institutional networking capability as a catalyst for sustainable supply chains in the manufacturing sector of Ghana: The role of green human resource management strategy and green dynamic capability

This study explores the influence of Green Human Resource Management Strategy (GHRMS) on supply chain environmental sustainability in manufacturing SMEs, emphasising the mediating role of green dynamic capability and the moderating effect of institutional networking capability. Quantitative data was gathered from 263 owners and managers in Ghana's manufacturing sector. The Covariant-Based Structural Equation Modelling (CB-SEM) approach within Amos (v.23) was employed to test the proposed hypotheses. The findings revealed that GHRMS significantly enhances supply chain environmental sustainability by fostering eco-conscious HR practices. Green dynamic capability partially mediates this relationship, enabling firms to develop and adapt sustainable competencies. Additionally, institutional networking capability strengthens the indirect effect of GHRMS on supply chain sustainability, demonstrating the crucial role of external networks in achieving environmental goals. These findings underscore the importance of both internal organisational capabilities and external collaborations in driving sustainable supply chain practices in emerging economies. This study provides strategic insights for firms aiming to integrate GHRMS into their environmental sustainability initiatives, fostering a greener and more resilient supply chain ecosystem.
