We study a vertical agricultural supply chain with a farmer cooperative who decides his agricultural product selling price and a social enterprise who makes her order quantity decision and resells products to the end market. The effect of market information and agricultural advice provided by the government on the system's outcomes is investigated. A two-stage game model is proposed to characterise this vertical relationship. The equilibrium decisions of the two players under different government supporting cases are derived. We contrast the system outcomes under different cases and conduct comparative analysis. It is found that (1) the farmer cooperative's profit increases if the government provides market information to him and the social enterprise at the same time; (2) the agricultural advice provided by the government can increase the benefits to each participant in the supply chain; (3) to maximise the total supply chain profit as well as its sustainability, the government may choose to provide market information to the social enterprise only; (4) when the wholesale price is intervened by the government or exogenously provided, the social enterprise's social responsibility concern can increase both the farmer cooperative's profit and the social enterprise's social payoff.

我们研究了一个垂直农业供应链，其中一个农民合作社决定农产品销售价格，一个社会企业决定订单数量并将产品转售给终端市场。调查了政府提供的市场信息和农业建议对系统结果的影响。提出了一个两阶段博弈模型来表征这种垂直关系。导出了不同政府支持情况下两个参与者的均衡决策。我们对比不同案例下的系统结果并进行对比分析。发现：（1）如果政府同时向农民合作社和社会企业提供市场信息，农民合作社的利润会增加；(2) 政府提供的农业建议可以增加供应链中每个参与者的利益；(3) 为最大化供应链总利润及其可持续性，政府可以选择仅向社会企业提供市场信息；（4）当批发价格受到政府干预或外生提供时，社会企业的社会责任关注可以增加农民合作社的利润和社会企业的社会收益。
