摘　　要：研究了零售商市场需求预测信息分享对双渠道绿色供应链绩效的影响。运用不完全信息动态博弈方法建立并求解零售商信息分享和信息不分享下的绿色供应链决策模型,得到贝叶斯均衡解和各方最优期望利润。研究发现:在双渠道绿色供应链中,若零售商对市场需求预测较为乐观,信息分享使得制造商更有动机提高产品绿色度;此外零售商信息分享总是有利于制造商利润增加,但并非总是使得零售商利润损失。当制造商绿色投资效率较高时,信息分享使得零售商利润增加,反之,信息分享使得零售商利润降低。对整个绿色供应链利润的影响取决于渠道间竞争强度、直销渠道市场份额及制造商绿色投资效率。最后用数值仿真验证了模型和结论的有效性。This paper aims at studyingthe effect of retailer’s demand information sharingonthe performance of dual-channel green supply chain.The green supply chain decision-making models with or without information sharing are established and solved by using incomplete information dynamic game method,and then the Bayesian equilibrium solutions and the optimal expected profits are obtained.The results show that in the dual-channel green supply chain,information sharing can motivate the manufacturer to improve product's green degree when the retailer is optimistic about the potential demand.Moreover,information sharing is always beneficial to the manufacturer.However,whether the retailer has an incentive to share demand information is uncertain.When the manufacturer’s green investment efficiency is higher,the retailer can obtain more profits from information sharing,otherwise the retailer would suffer a profit loss.Furthermore,the impact on the performance of the whole green supply chain depends on the competition intensity,the market share of direct channel and the green investment efficiency.Finally,the validity of the model and conclusions are verified by numerical simulation.
