推论2：如果因为极少数不可抗力，短时间无法通过市场自发交易完成产权配置和归属，则需要计划去管理市场。
首先，我们选取部分用户(小流量实验，样本量足够建模)随机分为实验组和对照组，对照组不发优惠券，实验组发放优惠券，用户最终是否购买为一个0-1变量；
然后，对整体实验数据用户购买行为进行建模；
最后，再用小流量实验训练得到模型对我们需要预测的全量用户进行条件平均处理效应估计，预测其发放优惠券所带来的增益值；
Today Xiaobian shares the keyword definition part of A journal paper "A dual supply chain revenue sharing contract considering online reviews and Rebates". Xiaobian will introduce this part of the content from the mind map, intensive reading content, knowledge supplement three plates, please readers to learn with Xiaobian.
In the numerical analysis part, scholars mainly conducted the analysis based on two factors considered, one is the sensitivity analysis of sales sensitivity, and the other is the sensitivity analysis of deduction point rate parameter. In the aspect of sales sensitivity sensitivity analysis, when the impact of sales effort on product market demand is small, the overall profit of the supply chain will increase with the improvement of sales effort level, and when the sales effort level increases to a certain extent, the overall profit of the supply chain will decrease with the improvement of sales effort level. Therefore, in actual supply chain decision-making, there is an optimal sales effort level to maximize supply chain profit, and the optimal sales effort level under centralized decision-making is greater than the optimal sales effort level under decentralized decision-making. After using two pricing contracts, it is found that manufacturers can optimize the overall profit of the supply chain by reducing the wholesale price. Traditional retailers increase the retail price of traditional channels by improving the sales effort level so as to maximize the profit. It can be found that the coordination decision weakens the influence of the increase of sales effort level on the increase of the optimal retail price. In terms of sensitivity analysis of deduction rate parameter, the increase of deduction rate of e-commerce platform causes more obvious double marginal effect of supply chain.
