Greening the manufacturing firms: do green supply chain management and organizational citizenship behavior influence firm performance?

The spontaneous organizational citizenship behavior towards environment (OCBE) of employees in the workplace is crucial to businesses' green development and low-carbon transition. However, it was not considered how such behavior could be encouraged for enhanced firm performance. From the natural resource-based view theory perspective, this study tests a model that investigates how green supply chain management practices, green culture, top management commitment, and OCBE, and influences firm performance. A structural equation model (SEM) was utilized to test the hypotheses using 600 survey questionnaires collected from manufacturing firms. The results show that green supply chain management indirectly affects firm performance through green culture and top management commitment. The results reveal that green culture and top management commitment positively and significantly mediate the relationship between green supply chain management and firm performance. Furthermore, the findings show that OCBE has a direct effect on firm performance. Moreover, the results highlight that OCBE has a positive moderating effect on the association between green supply chain management and firm performance. Finally, the study's findings and implications are disclosed to be useful policy instruments for organizations, administrations, and other stakeholders.
