Practitioners and researchers are increasingly paying great attention to green supply chain management (GSCM). However, no agreement has been reached on whether GSCM can directly improve company’s operational performance. From the perspective of resource-based view, this paper divides GSCM into internal environment management (IEM) and supplier environment management (SEM), and studies the mechanism of operation capabilities in the relationship between GSCM and company’s operational performance. Our findings suggest that (1) IEM partially improves company’s operational performance through operation capabilities. (2) SEM has positive impact on company’s operational performance through operation capabilities. The conclusion reveals the role of operation capabilities in the relationship between GSCM and company’s operational performance, opening up the black box of the relationship to some extent, which provides guidance for manufacturing companies
