摘要
为分散产品创新风险,买方作为创新主体与供应商签订合作协议——确定创新投入及创新产品原材料购买量,供应商需确定批发价格。在考虑研发风险的状况下,研究结果表明:1)若供应商承诺批发价,则能激励买方的创新投入,提高买方的期望收益及供应链的整体期望收益;2)给定期望需求,若市场变化较低,供应商偏好承诺批发价;反之,偏好推迟批发价决策;3)买方需求量的决策时机,对创新投入、期望批发价、买方期望需求和供应商期望收益无影响;4)买方若在市场信息揭示之前声明需求量(即需求承诺),会降低自身期望收益,进而降低供应链整体的期望收益;5)研发成功率的高低不改变合作契约间期望收益的相对关系。
In order to decrease risks in innovation,buyer,as the innovation subject,signs a cooperation agreement with supplier,and determines innovation investment and order quantity,buyer announces wholesale price.Consider R＆D risk,we obtain following conclusion：（a） supplier＇s commitment to wholesale price could stimulate supplier＇s innovation,and improve buyer＇s expected profits and also supply chain＇s,（b） for a given amount of expected demand,if demand variance is high,supplier prefers commitment to wholesale price,whereas,it prefers remain flexible,（c） regardless of level of demand variance,the buyer＇s expected profits are always larger if supplier commit in advance to a wholesale price than if it remains flexible,（c） when the supplier commit to price,innovation investment,wholesale price,expected quantity and supplier＇s expected profits do not depend on whether buyer has quantity flexibility or not,（d） however,buyer＇s commitment will sacrifice expect profits of both supply channel and its own.（e）the possibility of R＆D do not affect conclusion（a）（b）（c） and（d）.
