Adoption of green supply chain management practices in multi-tier supply chains: examining the differences between higher and lower tier firms

Abstract

Customer pressure has been widely discussed as the primary driver of green supply chain management (GSCM) practices. However, relatively little is known about supplier capabilities as a key mediator for GSCM practice adoption. Drawing from the resource dependence theory (RDT), we investigate how the interplay between customer pressure and supplier capabilities affects GSCM practice adoption along multi-tier supply chains. We test our hypotheses using multiple regression analysis based on a sample of 284 manufacturing firms operating at different tiers of a supply chain. Our results indicate that the supplier capabilities mediate the direct effect of customer pressure on the adoption of GSCM practices for focal firms. Specifically, we find a full mediation effect of supplier capabilities for higher-tier (i.e. OEM and system supplier) firms and a partial mediation effect for lower-tier (i.e. component and raw material) firms. Our findings provide support for the RDT perspective regarding GSCM. The focal firm’s adoption of GSCM practices as a response to customer pressure is dependent on the level of green resources and capabilities available from their suppliers. The level of such resource dependence varies between focal firms at higher- and lower-tier positions in a multi-tier supply chain.
