الملخص

This study explores the influence of green supplier selection practices on social performance at Muhimbili National Hospital (MNH), Tanzania’s leading referral hospital. With increasing global attention on sustainable procurement and its alignment with SDGs, particularly Goals 12 and 13, this research investigates how integrating sustainability criteria in supplier selection can improve waste management, delivery timeliness, and cost efficiency within the healthcare supply chain. Despite regulatory frameworks like Tanzania's Public Procurement Act (2023), challenges such as poor supplier compliance, weak monitoring, and limited awareness persist. Grounded in the Resource-Based View theory and employing a mixed-methods approach, this study fills a research gap by empirically examining whether green supplier practices such as environmental certification and compliance with green regulations positively impact social performance at MNH. Findings aim to inform hospital administrators, policymakers, and researchers about the strategic value of sustainable procurement in enhancing operational and social outcomes. The results reveal a moderate to strong positive correlation (R = 0.650) between green supplier selection practices and social performance, with 48% of the variability in social performance explained by sustainability criteria, supplier environmental certification, and compliance with green regulations (R² = 0.480). The ANOVA results (F = 9.600, p = 0.000) confirm the statistical significance of these predictors. Coefficient analysis shows positive and significant contributions from sustainability criteria (β = 0.355, p = 0.020), supplier environmental certification (β = 0.276, p = 0.018), and compliance with green regulations (β = 0.221, p = 0.032). Perception data supports these findings, with high ratings for suppliers investing in renewable energy (mean = 4.09) and compliance with environmental regulations (mean = 4.00). However, lower ratings for prioritizing sustainable suppliers (2.55) and evaluating waste minimization efforts (2.37) highlight gaps in policy enforcement and awareness. Moderate scores for audits and supplier engagement (means ≈ 2.55–2.90) indicate the need for improved monitoring and collaboration. Overall, MNH demonstrates progress in integrating green procurement, but stronger enforcement, enhanced training, and deeper supplier partnerships are essential to maximize social and environmental benefits.
