Supply chain integration is a key strategic priority for firms striving to achieve efficiency and responsiveness in their supply chain. This paper discusses how the supply chain integration is affected by supply chain partnerships, information quality and information sharing. This paper presents and tests a research model using a sample of 60 Korean firms that are involved in the supply chain activities. The results suggest that the supply chain partnership directly affects the quality of information being shared but not necessarily the scope and frequency of it. Rather, supply chain partnership indirectly affects information sharing, via information quality. Management implications of this research and future research issues are presented, as well.
