摘　　要：To investigate contract stability in the company and farmer mode and to explore control measures of market price risk and production risk,a multiperiod game model was established in this study.Considering multiple periods and losses caused by deaths simultaneously,a stable contract price interval depending on the breaching penalty,transaction cost,spot market price,and quantity of pigs was observed.Results indicate that the higher the penalty and transaction cost savings,the better the stability of the contract;the contract price should be negotiated around the weighted average of the spot market price.When the production risk is higher,hog insurance can significantly improve the contract stability;when the market price is lower,hog price index insurance improves the contract stability by guaranteeing the company income;when the market price is higher,the profit-returning mechanism improves the stability by protecting farmers incomes.Applying three measures simultaneously results in the best stability.Examples based on data from 2014 to 2018 in Henan Province,China,were given.为研究公司和农户模式下生猪生产合同的稳定性,探索市场价格风险和生猪产量风险的管控措施,建立了多周期博弈模型.同时考虑多个养殖周期和生猪死亡导致的损失,得到由违约成本、交易成本、生猪现货市场价格和生猪饲养数量决定的稳定合同价格区间.分析表明:违约成本和节约的交易成本越高,合同的稳定性越好;合同价格应协商为现货市场价格的加权平均值.当生猪产量风险高时,生猪保险能显著提高合同稳定性;当市场价格较低时,生猪价格指数保险通过保障公司的收益提高合同稳定性;当市场价格较高时,收益返还机制通过保护农户的收益提高合同稳定性.同时采纳3种措施时,合同稳定性最好.最后,以河南省2014—2018年的数据为例进行了实证分析.
