Study On The Influence Of Service Relationship On The Supply Chain Information Sharing And Trust Decision

Coordinating the supply chain is the vital objective of any supply chain manaegment providing satisfactory services. Any coordination failure is associated with incentive conflicts of channel members, each member should pay attention to the relationships with each other. Service relationship is the most important part of the supply chain relationship, leading to more information sharing and more trust. Supply chain information sharing is one of the more important studies in literature, and the study of asymmetric information is the focus of research scholars. Because of asymmetric information, information-sharing and decision-making trust between suppliers and manufacturers is a key supply chain coordination.As information technology developing,more supply chain members rely on information-sharing.However, downstream manufacturers closer to the market demand, and have more private information than supplier. Upstream parts suppliers determine the capacity based the sharing of manufacturer private information. To ensure adequate supply, manufacturer shares private demand information with supplier, but with a cheating motivation. In view of the manufacturer’s information sharing, supplier determines capacity investment and makes trust decision. Our study shows that low deceive cost will cause the untruthful manufacturer information sharing. Followed by the establishment of the service value model, and analyze how the service relationship affects information sharing and trust decision. The results show that service value is high enough, the value of services enables manufacturers to share information truly, the supplier can fully trust the manufacturer information sharing; If the service low value, manufacturer has an incentive to inflate private information in a costless communication, the supplier should doubt manufacturers information sharing.
