This study analyzed the effects of IT and Process cooperation approach on supply chain performance through information sharing and supply chain strategies. In addition to the direct impact of IT/Process cooperation and supply chain performance, an analysis of indirect mediation effects linked to information sharing and the implementation of supply chain strategies was performed. Through theoretical review of each concept, the structural equation model and hypothesis were established and tested, and IT/Process cooperation had a positive impact on supply chain cost performance and IT cooperation had a positive impact on supply chain service performance. In addition, this study examined that the relationship between IT/process cooperation and supply chain service performance was mediated through information sharing and supply chain responsive strategy, and the relationship between process cooperation and supply chain cost performance was mediated through information sharing and supply chain efficient strategy. And information sharing was shown to have a mediation effect between IT/Process cooperation and supply chain strategies, supply chain efficient strategy had a mediation effect between information sharing and supply chain cost performance, supply chain responsive strategy had a mediation effect between information sharing and supply chain service performance. This study contributes to the literature on a series of processes in which IT and Process cooperation approach are linked to information sharing, supply chain strategies and supply chain performance by theoretically explaining, and in practice provides a step-by-step guide for establishing and pursuing supply chain objectives in the organization.
