Abstract

Objective: This study examines how green procurement and strategic sourcing contribute to sustainable development and economic resilience in Ghana’s public sector, with particular attention to the moderating role of supplier collaboration. The paper addresses the growing need for procurement systems in developing economies to simultaneously deliver environmental sustainability and resilience against economic shocks.
Methods: An explanatory research design was adopted, and data were collected from 421 public procuring entities in Ghana using a stratified random sampling technique. Partial Least Squares Structural Equation Modelling (PLS-SEM) was employed to analyse the data and test both direct and moderating effects.
Results: The results show that green procurement positively influences sustainable development (β = 0.412, p < 0.001) and economic resilience (β = 0.287, p < 0.001). Strategic sourcing also has significant positive effects on sustainable development (β = 0.356, p < 0.001) and economic resilience (β = 0.398, p < 0.001). Supplier collaboration significantly moderates all examined relationships, with interaction effects ranging from β = 0.152 to β = 0.193 (p < 0.05). The model explains 53.8% of the variance in sustainable development and 49.2% in economic resilience.
Conclusion: The findings demonstrate that green procurement and strategic sourcing are effective drivers of sustainable development and economic resilience when supported by strong supplier collaboration. This evidence highlights the importance of collaborative procurement strategies in strengthening public-sector performance in developing economies. The results provide practical guidance for policymakers and procurement managers seeking to align procurement systems with sustainability goals and enhance resilience to future economic disruptions.
