摘要
基于博弈论,构建了政府和冷链食品企业之间的纯战略博弈模型和混合战略博弈模型,并对博弈模型中的纯战略Nash均衡、占优战略Nash均衡和混合战略Nash均衡进行了分析,探讨了两者间的博弈关系以及不同情况下各自的最优策略选择,揭示了影响政府积极监管或消极监管、冷链食品企业提供高质量或低质量食品的关键因素。通过本文分析,研究结果表明:政府积极监管概率与冷链食品企业提供高质量冷链食品的成本、提供低质量冷链食品的成本、冷链食品所处温度和政府监管部门对冷链食品企业的惩罚力度有关;冷链食品企业提供高质量冷链食品的概率与政府监管成本、对冷链食品企业的惩罚力度和上级对政府监管部门失职行为的惩罚力度有关。最后,提出了政府和冷链食品企业共同提高食品质量安全的对策与建议。
In this paper,based on the game theory,the game model of pure strategy and mixed strategy between government supervision department and cold-chain food enterprise are established,the pure strategy Nash equilibrium,dominant strategy Nash equilibrium and mixed strategy Nash equilibrium in the theory game models are aanalyzed,and the game relationship between them and their optimal strategy choice are disussed.Meanwhile the key factors that influence the government actively supervise or negatively supervise,cold-chain food enterprises,provision of high quality or low quality cold-chain food are revealed.The research results show that,cost of cold-chain food enterprises' provision of high quality cold-chain food or low quality of cold-chain food,cold-chain food temperature,government supervision department penalties to the cold-chain food enterprise influence the probability of government actively supervise;government regulatory cost,penalties for cold-chain food enterprises,and the superior penalties for the behavior of the government's dereliction of duty influence the probability of enterprises' provision high quality cold-chain food.Finally,many suggestions are prvided to improve the quality and safety of cold-chain food.
