Relationship marketing has been characterized as a fundamental reshaping in industrial marketing. Suppliers are recognizing the value of relationship marketing as a means of retaining existing customers in marketing channels, illustrating relationship bonds as important strategies to increase customers' long term loyalty and benefits. Scholars have probed relationship bonds by financial bonds, social bonds, customization bonds, and structure bonds respectively. However, research exploring the relationship bonds in industrial marketing channels remains limited. In this article, we attempt to fill this research gap by investigating how relationship bonds are initiated, built, nurtured and sustained between suppliers and dealers in industrial channels through qualitative studies. Results, implications and directions for future research are then discussed.
