Dear, this is the LearingYard Academy!
Today, the editor brings the "Game Analysis of Agricultural Supply Chain Finance Evolution under Government Involvement Scenario".
Welcome to visit！
1 内容摘要（Content summary）
今天小编将从“思维导图、精读内容、知识补充”三个板块，解读分享《政府介入情境下农业供应链金融演化博弈分析》一文的第五章多情境模拟-A情景模拟中的后半部分。
Today, I will share the second half of Chapter 5, Multi-Situation Simulation-A Scenario Simulation of the article "Analysis of Agricultural Supply Chain Finance Evolution Game under the Scenario of Government Involvement" from the three sections of "Thinking Guide, Intensive Reading and Knowledge Supplementation".
2 思维导图（Mind mapping）
3 精读内容（Intensive reading content）
3.1 模型描述（model description）
这一章节在之前供应链金融合作博弈模型基础上，加上政府主体，且政府担任策略扰动者，率先做出自我利益让步（为供应链参与方提供政策性补偿），引导其他参与主体策略演化，对相关参数进行修改，构建新的演化博弈模型。
In this chapter, the government is added on the basis of the previous supply chain finance cooperative game model, and the government, as a strategic intervener, takes the lead in making self-interested concessions (providing policy compensation for supply chain participants), guiding the strategic evolution of other participants and modifying the relevant parameters, so as to construct a new evolutionary game model.
经过土地流转，传统的“公司+农户”订单合作模式演化为政府介入下的“公司+大户”模式，相应的供应链运作良好额外总收益由W0变为W1（W1 > W0），相应的大户投资收益率为 b1+（b1+ > b1）。
After the land transfer, the traditional "company+farmer" order cooperation model evolves into the "company+large household" model under the government intervention, and the corresponding supply chain operates well, with the additional total return changing from W0 to W1 (W1>W0), and the corresponding investment return of the large household is b1+ (b1+>b1).

3.3 模型构建(model building)
根据上述假设条件，构建“公司+大户”订单农业供应链合作双方博弈收益矩阵。然后计算农业龙头企业和大户不同决策下的期望收益及综合期望，并得出其复制动态方程，具体步骤如下图：
According to the above assumptions, we construct the game benefit matrix of "company + large household" order agriculture supply chain cooperation. Then, we calculate the expected returns and comprehensive expectations under different decisions of leading agricultural enterprises and large households, and derive their replication dynamic equations, and the specific steps are shown in the figure below:
4 知识补充（Knowledge supplement）
演化博弈分析的重点是什么？（What is the focus of evolutionary game analysis?）
策略稳定性：研究不同策略在群体中的稳定性和传播趋势。重点关注哪些策略能够在演化过程中获得优势并稳定下来，成为群体中的主导策略。
Strategy Stability: Examines the stability and propagation trends of different strategies in groups. Focuses on which strategies are able to gain advantage and stabilize during evolution and become the dominant strategy in the group.
进化稳定策略（ESS）：寻找进化稳定策略，即在给定环境条件下，当大多数个体采用该策略时，它无法被任何其他替代策略所取代。这种策略通常是演化过程中的均衡点。
Evolutionarily Stable Strategies (ESS): The search for an evolutionarily stable strategy, i.e., a strategy that cannot be replaced by any other alternative strategy when the majority of individuals adopt it under a given environmental condition. This strategy is usually the equilibrium point in the evolutionary process.
博弈动态：分析策略在演化过程中的动态变化，包括策略的出现、传播和消失。关注哪些因素影响了策略的演化路径和速度。
Game Dynamics: Analyzes the dynamics of the strategy during the evolutionary process, including the emergence, propagation, and disappearance of the strategy. Focuses on what factors influence the evolutionary path and speed of the strategy.
群体结构：考虑群体内个体之间的互动结构，如亲缘关系、空间分布等因素，对策略的演化和稳定性产生影响。
Group Structure: Considers the structure of interactions between individuals within a group, such as kinship, spatial distribution, and other factors that influence the evolution and stability of strategies.
合作与竞争：分析合作与竞争对演化博弈的影响。研究合作性策略如何在群体中获得优势，并与竞争性策略相互作用。
Cooperation and Competition: Analyzes the effects of cooperation and competition on the evolutionary game. Examine how cooperative strategies gain advantage in groups and interact with competitive strategies.
