Abstract: Aiming at the problem that the manufacturer outsourced to the supplier,the impact of R&D uncertainty on supplier innovation benefits was analyzed.The consumer utility function was constructed based on Hotelling model;the maximum profit and the optimal quality of supply chain were derived respectively under three different contract scenarios: the wholesale price contract,the quality-dependent wholesale price contract and the revenue-sharing contract when R&D uncertainty existed in the development.The influence of R&D uncertainty on innovation benefits of suppliers was analyzed.The results showed that the benefit of manufacturer would be higher than its reservation profit in the quality-dependent wholesale price contract with a low R&D cost;only the revenue-sharing contract could coordinate the supply chain when the R&D cost was higher,and the corresponding increase in proportion of profits could effectively encourage the supplier to innovate.

Key words: R&D uncertainty, supplier innovation, supply chain contracts, Hotelling model
