Do motives matter? Examining the relationships between motives, SSCM practices and TBL performance

Purpose: Drawing on multi-theoretical lenses and a combination of supply chain and business ethics literature, this study aims to investigate the role of motives in driving sustainable supply chain management (SSCM) practices and sustainable performance. Design/methodology/approach: Using a sample of 205 supply chain companies in the USA, the authors apply structural equation modeling (SEM) analysis to empirically test the proposed model and seven hypothesized relationships. Findings: Results of the study underscore the critical role of moral motives, while highlighting that all three types of motives (instrumental, relational and moral) are robust in driving SSCM practices and achieving improvement in all three dimensions of sustainable performance–economic, environmental and social. Research limitations/implications: This research can help supply chain scholars develop a more robust subfield of motivation-based SSCM research to gain a deeper understanding of how motives may differentially predict sustainable supply chain practices and performance. Practical implications: The results of this study demonstrate the critical links between moral motivation and the triple bottom line (TBL) performance and suggest that managers pay more attention to moral motives in their decision-making. Originality/value: This study bridges gaps in the extant literature by incorporating motivation-based antecedents, expanding the scope of SSCM practices, including the social dimension of sustainability and investigating the mediating effects of SSCM practices on the links between motives and the TBL performance.
