Abstract: In order to analyze the impact of the retailer's risk preference on pricing policy and information sharing value, the retailer's decision objective function is characterized by using expected profit and conditional valueatrisk（CvaR）as a weighted average of objective criteria and the optimal pricing policies and the demand information sharing values with the retailer's different risk preference are studied. The results show that the wholesale price does not matter λ when there is no information sharing. The optimal wholesale price, the optimal retail price and retailer's information sharing value will increase when the market uncertainty information shows demand will increase, and the supplier's and supply chain's information sharing value will decrease with the increasing of λ. And when the market uncertainty information shows demand will decrease, the optimal wholesale price, the optimal retail price and retailer's information sharing value will decrease with the increasing of λ, but the supplier's and supply chain's information sharing value will increase.

Key words: risk preference, pricing policy, demand information sharing values, expected profit and conditional value at risk
