研究了零售商预测信息的分享对存在消费者绿色偏好以及制造商横向竞争的绿色供应链的影响。分别建立和求解了四种信息分享模型（无分享，仅与绿色成本高的制造商分享，仅与绿色成本低的制造商分享以及与两制造商均分享）。比较研究表明，无论哪种模式零售商进行预测信息分享对其自身是不利的，但能增加两制造商预期利润。同时发现信息分享对各供应链成员的价值以及各方对信息分享模式的偏好取决与两制造商间的竞争水平以及市场份额的差异，同时也受到制造商绿色成本系数大小的制约。

This paper analyzes how the forecasting information sharing of the retailers influences the supply chain which exist the consumers’ green preference and the manufacturers’ horizontal competition. It establishes to solve the four information-sharing model (no sharing, share only with high green cost manufacturers, share only with low green cost manufacturers to share and share with the two manufacturers). The results show that the retailers will loss if they want to take the forecasting information sharing, but it can make the manufacturers increase their forecasting profits. It also shows that the value of supply chain members under the information sharing and their preference to information-sharing mode not only depend on the level of manufacturers’ competition and the differences of their market share, but also by the constraints of the manufacturer’s green cost coefficient.
