Mixed sustainability motives, mixed results: the role of compliance and commitment in sustainable supply chain practices

Abstract

PurposeAs supply chain sustainability has become more urgent than ever before, this study aims to provide a more nuanced understanding of how supplying firms’ sustainability motives influence their compliance and commitment, as well as sustainable performance, as they respond to buyers’ sustainable supplier management programs.Design/methodology/approachTo investigate the intriguing links among sustainability motives, compliance/commitment and sustainable performance of supplying firms, this paper draws on multidisciplinary literature and collects empirical data from 281 supplying firms in China to test the proposed model and hypotheses using structural equation modeling.FindingsInstrumental and moral motives make comparable contributions to compliance; moral motives exert stronger influence on firms’ commitment to sustainable practices. In addition, although compliance has a greater impact on economic and environmental performance, commitment is far more robust in improving environmental and social performance.Research limitations/implicationsUnlike most research on motives that has been theoretical, this study represents one of the few empirical analyses of how motives may affect sustainable performance. Examining the challenges from the perspectives of supplying firms, it also adds to the SSCM literature by making clear how compliance and commitment may differentially predict sustainable performance.Practical implicationsAlthough instrumental and moral motives can be complementary in advancing sustainable practices, it is imperative for firms to integrate moral considerations into sustainability decision-making and move beyond compliance, if they are to contribute meaningfully to a better society and cleaner environment.Originality/valueThis is the first large-scale empirical investigation on the links among motives, compliance, commitment and sustainable performance from the perspectives of suppliers.
