Purpose Interorganizational dependence is considered as a liability for each firm and needs to be managed properly. Rather than exploring the opportunistic outcome of dependence, the authors focus on the moderating role of supply chain boundary spanners' guanxi . This study tends to uncover the way and the conditions under which boundary spanners' guanxi influences dependence-opportunism relationships. Design/methodology/approach Using a survey of 380 buyer–supplier exchanges in China, this study first examines the relationship between dependence and opportunism, then assesses the contingent role of boundary spanners' guanxi and further tests how unfairness perception and legal inefficiency alter the role of guanxi in managing dependence. Findings This study finds that buyer dependence increases supplier opportunism while supplier dependence lowers supplier opportunism. Boundary spanners' guanxi weakens the opportunism-facilitating impact of buyer dependence and mitigates the opportunism-restricting effect of supplier dependence. However, unfairness perception would attenuate the value of guanxi in restricting depended sides' opportunism but strengthen the value of guanxi in motivating depending sides' opportunism; legal inefficiency would amplify the value of guanxi in facilitating depending suppliers' opportunism. Originality/value First, the study enriches supply chain dependence studies by incorporating interpersonal guanxi into the investigation of dependence-opportunism relationships. Second, the study adds to the supply chain management literature by uncovering a contrasting role of guanxi in influencing the dependence-opportunism relationship. Third, the study incorporates an agency view to uncover two boundary conditions under which guanxi is mobilized for personal interest seeking or for organizational purposes.
