關係對協同商務的執行很重要，但其相關研究卻很少。本研究採個案法探討企業協同商務夥伴關係之決定因素與影響效果。經由對四家台灣企業的探討結果顯示，關係的品質與關係的緊密無相關，並且組織文化、資源依賴及協同科技是協同關係的主要決定因素。好的組織文化，深的資源依賴，以及高度的協同科技應用有利協同關係的發展。最後，協同關係會影響績效，但在環境不確定性高的情況下，協同關係對績效的影響可能不顯著。本研究指出協同商務中，協同關係如何形成與運作，提供後續研究新觀點，並可應用於實務中，藉由有效地管理協同關係管理，達到成功的協同商務。

While relationships are crucial in conducting collaborative commerce (c-commerce), there has been very little c-commerce research on this topic. This study aims to explore the determinants and effects of relationships in c-commerce using the case study method. The study results of four Taiwanese enterprises indicate that the quality of relationship is not correlated with the closeness of the relationship. Furthermore, organizational culture, resource dependency and collaborative technology are the main determinants of collaborative relationships. Good organizational culture, deeper resource dependency and higher application of collaborative technology would facilitate the development of collaborative relationships. Finally, collaborative relationships will affect performances; however, in highly uncertain environments, the influence of collaborative relationships on performances may not be significant. This study reveals how a collaborative relationship forms and acts in ccommerce, which provides a new perspective for further research and can be applied in practice to achieve successful c-commerce through managing collaborative management effectively.
