上期我们分析了结论1,另外我们也可以通过之前的分析得到结论2：SS 结构下，供应商 Si的批发价格不仅与其生鲜农产品品质相关，而且与竞争方的生鲜农产品的品质相关。当两供应商生鲜农产品品质差异值低于临界值时，零售商只会向提供更高品质生鲜农产品的供应商 Si订货。

具体来看，若竞争方供应商提高生鲜农产品品质，供 应商将降低其生鲜农产品的批发价格，导致其生 鲜农产品的市场零售价格降低：供应商提供的生鲜农产品品质提高的值不同时，会造成的两种情况发生：供应商提高其批发价格或零售商提高其市场零售价格。

结论 2 表明，当生鲜农产品品质提升到一定水平时，生鲜农产品的批发价格或市场零售价格会增加。

In the previous period we analysed conclusion 1, and we can also draw conclusion 2 from the previous analysis: under the SS structure, the wholesale price of supplier Si is not only related to the quality of its fresh produce, but also to the quality of the competitor's fresh produce. When the difference in quality between the two suppliers is below a critical value, the retailer will only order from the supplier Si who offers higher quality produce.

Specifically, if the competing supplier improves the quality of its fresh produce, the supplier will lower its wholesale price of fresh produce, resulting in a lower retail market price for its fresh produce: the difference in the value of the improved quality of the fresh produce offered by the supplier will result in either the supplier raising its wholesale price or the retailer raising its retail market price.

Conclusion 2 shows that when the quality of fresh produce is increased to a certain level, the wholesale or retail market price of fresh produce increases.

知识补充

我们已经了解过了供应链契约的类型及其含义，今天让我们学习一下供应链契约的基本模型吧，首先为大家带来的是供应契约的基本假设。

1)供应链是由单一供应商和单一零售商组成的二级供应链，供应商和零售商单独决策，即该供应链为分散式决策供应链；2)销售商面临一个随机的市场需求，当市场需求大于订货量时，零售商存在缺货成本，当市场需求小于订购量时，零售商存在过量的持有成本；3)根据LF博弈理论，假设供应商是领导者，零售商是追随者，供应商给出一套契约参数，零售商根据这些参数确定最优订货量；4)供应商和零售商是风险中性和完全理性的，即两者均根据自身利润最大化进行决策；5)销售价格、需求分布和库存成本参数等信息是对称的。

We have already understood the types of supply chain contracts and their meanings, let's learn the basic model of supply chain contracts today. The first thing we bring to you is the basic assumptions of supply contracts.

1) The supply chain is a secondary supply chain consisting of a single supplier and a single retailer, where the supplier and retailer make separate decisions, i.e. the supply chain is a decentralised decision making supply chain.

2) that the seller faces a stochastic market demand and that there are out-of-stock costs for the retailer when the market demand is greater than the order quantity and excess holding costs for the retailer when the market demand is less than the order quantity.

3) according to LF game theory, the supplier is assumed to be the leader and the retailer the follower, and the supplier gives a set of contractual parameters according to which the retailer determines the optimal order quantity.

4) suppliers and retailers are risk neutral and perfectly rational, i.e. both make decisions based on maximising their own profits.

5) information such as sales price, demand distribution and inventory cost parameters are symmetric.
