Abstract: Considering a supply chain consisted of two manufactures and a retailer, in the face of consumers with low-carbon preferences, manufactures take the initiative to perform carbon reduction research and development, and the retailer shares the manufactures’ research and development costs, the effects of research and development spillover and consumers’ environmental awareness on the manufactures’ carbon reduction research and development strategy are analyzed. It is shown that when the research and development spillover is much lower and consumer environmental awareness is very high, the manufactures will choose the strategy of research and development competition if the retailer can properly compensate them. Then, when the research and development spillover is much lower and consumer environmental awareness is especially high, the manufactures will choose the strategy of research and development cooperation. However, when both research and development spillover and consumer environmental awareness are much higher, the manufactures will choose the strategy of research and development cooperation if they can share the retailer’s revenue. Finally, when research and development spillover is much higher and consumer environmental awareness is especially high, the manufactures will also choose the strategy of research and development cooperation without any revenue sharing contract.

Key words: carbon reduction research and development, consumer environmental awareness, research and development competition, research and development cooperation

摘要： 考虑两个制造商和单个零售商构成的供应链，面对具有低碳偏好的消费者，制造商主动实施减排研发、零售商分担制造商的研发成本，研究了研发成果溢出和消费者低碳偏好对制造商研发策略选择的影响。结果表明：当研发溢出率很低和消费者低碳偏好程度很高时，如果零售商能适当补偿制造商，制造商会选择研发竞争；当研发溢出率很低和消费者低碳偏好程度特别高时，制造商会选择研发合作；当研发溢出率和消费者低碳偏好程度均较高时，如果制造商能分享零售商的部分利润，制造商会选择研发合作；当研发溢出率较高和消费者低碳偏好程度非常高时，无需任何利益分享契约，制造商会选择研发合作。
