本研究利用資源基礎理論與吸收能力觀點來探討行銷通路中關係知識儲存與雙方競爭優勢兩者之間的關聯。本研究延伸Dyer and Singh (1998) 以關係觀點探討組織間的競爭優勢來源,提出關係資本與交易專屬性投資能有助於關係知識儲存,進而達成雙方的競爭優勢。研究結果顯示關係資本與交易專屬性投資皆能顯著地正向影響三種關係知識儲存:互動知識、程序知識與分配知識。除此之外,互動知識儲存與分配知識儲存顯著地正向影響雙方競爭優勢,特別是互動知識儲存對於雙方競爭優勢最具影響。 Drawing on the resource-based view (RBV) and the absorptive capacity perspective, this study examines the relationship between relational knowledge stores (RKS) and dyadic competitive advantage in marketing channel relationships. We are inspired by Dyer and Singh’s relational view of interorganizational competitive advantage (1998), and propose that relational capital and transaction-specific investments facilitate RKS, which in turn achieve dyad competitive advantage. The results show that relational capital and transaction-specific investments have positively influence on the three dimensions of RKS (interactional, procedural, and distributional), additionally, interactional and distributional RKS positively affect dyadic competitive advantage. Particularly, interactional RKS has the strongest effect on dyadic competitive advantages. Finally, implications and future research issues are discussed.
