基于粮食主产区湖南、山东两省436份种粮大户调查数据，运用二分类Logit模型实证分析价值认知、制度环境对种粮大户质量安全控制行为的影响及代际差异，并检验制度环境在价值认知影响种粮大户行为中的调节效应。结果表明：价值认知对种粮大户质量安全控制行为有正向作用，其中社会价值认知对中生代种粮大户的影响更为显著，生态价值认知对新生代种粮大户的影响更为显著；引导制度、激励制度对种粮大户质量安全控制行为具有正向作用，其中引导制度对新生代和中生代种粮大户的影响更为显著，而约束制度对老一代种粮大户质量安全控制行为有显著的抑制作用；制度环境是种粮大户价值认知与质量安全控制行为之间的重要调节变量，约束制度和激励制度在价值认知对老一代种粮大户质量安全控制行为的影响中有负向调节效应。

Based on the survey data of 436 large grain growers in major grain-producing areas of Hunan and Shandong provinces, the impact of value cognition and institutional environment on the quality and safety control behavior of large grain growers and its intergenerational differences have been analyzed by using the Binary Logit Model and the moderating effect of the institutional environment on the behavior of large grain growers impacted by value cognition has been validated. The results show that the value cognition has a positive impact on the quality and safety control behavior of large grain growers. Among them, the social value cognition has a significant impact on the middle generation of large grain growers, and the ecological value cognition has a significant impact on the new generation of large grain growers. Guidance system and incentive system have a positive impact on the quality and safety control behavior of large grain growers. Among them, the guidance system has a significant impact on the new generation and old generation of large grain growers while the constraint system has a significant inhibitory effect on the quality and safety control behavior of the older generation of large grain growers. Institutional environment is an important moderating variable between the value cognition and quality and safety control behavior of large grain growers. The constraint system and the incentive system have a negative moderating effect on the impact of the value cognition on the quality and safety control behavior of the older generation of large grain growers.
