零售商信息分享对制造商绿色产品设计的影响研究

The Retailer’ Information Sharing in Green Product Design by the Manufacturer

摘要:

研究零售商信息分享对绿色供应链中制造商绿色产品设计的影响,包括开发密集型绿色产品(DIGP)和边际成本密集型绿色产品(MIGP)。分别建立了集中式决策情形以及分散式决策情形下零售商信息分享与不分享的模型。通过比较分散式决策情形下的贝叶斯均衡解可以得到：与信息不分享相比,当零售商分享预测信息且预测信息比较乐观时,两类产品批发价和零售价都提高,DIGP的绿色度提高,但MIGP的绿色度不变；随着零售商预测需求信息精确度的提高,制造商和零售商的期望利润都提高；零售商信息分享会使制造商的期望利润提高,但是零售商本身的期望利润降低；零售商信息分享使MIGP供应链的期望利润降低；当绿色成本系数适中时,信息分享使整个DIGP供应链的期望利润提高,否则,DIGP供应链的期望利润降低。最后用改进的K-S法对供应链进行协调,该协调不仅可以激励零售商信息分享,还能使供应链总期望利润达到集中式决策的水平。

Abstract:

This paper studies the retailer’ information sharing in green product design by the manufacturer in a green supply chain, which includes the development-intensive green product (DIGP) and margin cost-intensive green product (MIGP). We develop central centralized decision-making model and centralized decision-making models which contain information sharing and no information sharing. We obtain that, by comparing Bayes equilibria in different cases, when the retailer share optimistic forecast information, the wholesale price and retail price increase, the DIGP’s greenness increase, but MIGP’s greenness remain unchanged; with the increase of the prediction accuracy, the manufacturer and the retailer’s expected profits raise; information sharing benefits the manufacturer while hurt the retailer himself; information sharing will make the MIGP supply chain suffer a loss; if the greenness is moderate, information sharing benefits the DIGP supply chain, otherwise, it hurts the DIGP supply chain. Finally, we coordinate the supply chain using the improved K-S method, which not only motivates the retailer to share information, but also increase the total expected profit of the supply chain to the centralized decision-making.
