精读内容
首先说明了本文中研究的问题是什么，以及描述了涉及到的要素。
研究的对象：两竞争性供应商 S1、S2和单零售商 R 组成的生鲜农产品供应链系统
其中将一家供应商设为 Si，i = ( 1，2)
与其竞争的供应商为 Sj ，则 j = 3 – i．
It is first explained what the problem studied in this paper is, as well as describing the elements involved.
The object of the study: a fresh produce supply chain system consisting of two competing suppliers S1 and S2 and a single retailer R
where one supplier is set as Si with i = ( 1, 2)
The competing supplier is Sj , then j = 3 - i.
作者还强调在这个模型中，假设了两家竞争性供应商通过同一家零售商销售同类异质生鲜农产品，低品质的生鲜农产品可替代高品质的生鲜农产品，两者形成竞争关系。
其中同类是指可以相互替代的产品，但有同质、异质之分，本文的异质显然是指产品之间存在着差异，比如品牌、款式、性能及售后服务等方面。
此外在本文的模型中，作者还假设了以下条件
供应商Si决策生鲜农产品的批发价格为 wi
零售商决策零售边际利润 mi，
产品的订货量为 qi
The authors also emphasize that in this model, two competing suppliers are assumed to sell similar heterogeneous fresh produce through the same retailer, and the lower quality fresh produce can substitute for the higher quality fresh produce, and the two form a competitive relationship.
Where similar refers to products that can be substituted for each other, but there is a distinction between homogeneous and heterogeneous, heterogeneous in this paper obviously refers to the differences between products, such as brand, style, performance and after-sales service.
In addition in the model of this paper, the authors assume the following conditions
Supplier Si decides the wholesale price of fresh produce as wi
the retailer decides the retail marginal profit mi
The order quantity of the product is qi
为了方便理解，作者画出了供应商竞争的生鲜农产品供应链流程图，两个竞争性的供应商分别向零售商给出不同的批发价，零售商销售给消费者也因此获得不同的边际利润，反过来不同的批发价格下导致的订货量也不同。
To facilitate understanding, the authors draw a flow chart of the fresh produce supply chain with competing suppliers, where two competing suppliers each offer different wholesale prices to the retailer, and the retailer sells to consumers with different marginal profits as a result, which in turn leads to different order volumes at different wholesale prices.
本文就是根据以上设置的供应链模型，分析供应链权力结构及生鲜农产品竞争性对最优决策的影响。通过建立二对一生鲜农产品供应链模型，给出供应链企业最优决策，然后分析供应链三种不同的权力结构及生鲜农产品竞争性对供应链企业决策的影响。
This paper is to analyze the influence of supply chain power structure and fresh produce competitiveness on optimal decision making based on the supply chain model set up above. By setting up a two-pair fresh produce supply chain model, the optimal decision of supply chain enterprises is given, and then the influence of three different power structures of the supply chain and the competitiveness of fresh produce on the decision of supply chain enterprises is analyzed.

知识补充
本文的模型研究中，涉及到了斯坦伯格博弈，从今天开始，我将和大家一起学习一下关于斯坦伯格博弈的内容，今天就先让我们了解一下斯坦伯格博弈的概念吧。
Stackelberg Game，即斯塔克伯格博弈，是一个两阶段的完全信息动态博弈，博弈的time是序贯的。主要思想是双方都是根据对方可能的策略来选择自己的策略以保证自己在对方策略下的利益最大化，从而达到纳什均衡。在该博弈模型中，先作出决策的一方被称为leader，在leader之后，剩余的players根据leader的决策进行决策，被称为followers，然后leader再根据followers的决策对自己的决策进行调整，如此往复，直到达到纳什均衡。
The model study in this paper involves the Stackelberg Game. Starting from today, I will learn a little bit about the Stackelberg Game with you. Today, let's first understand the concept of the Stackelberg Game.
Stackelberg Game, or Stackelberg Game, is a two-stage full information dynamic game, where the time of the game is sequential. The main idea is that both parties choose their own strategies based on the other party's possible strategies to ensure that their interests are maximized under the other party's strategy, thus reaching a Nash equilibrium. After the leader, the remaining players make decisions according to the leader's decisions, called followers, and then the leader adjusts his decisions according to the followers' decisions, and so on until the Nash equilibrium is reached.
