从加强食品供应链信息共享角度,应用演化博弈理论和系统动力学方法,在分析食品供应链信息共享影响因素的基础上,首先建立无政府惩罚下食品供应商和加工商之间的演化博弈模型,接着在模型中加入“政府惩罚”这一外部参数,通过动力学仿真表明:信息共享概率随共享成本、单独不共享收益反向变动;随共享超额收益、单独共享收益和政府惩罚力度同向变动。同时证明了用系统动力学方法研究博弈问题的可行性。
From the perspective of enhancing information sharing in food supply chain, this paper applies evolutionary game theory and system dynamics method to analyze the influencing factors of information sharing in food supply chain. First, an evolutionary game model between food suppliers and processors under anarchic punishment is established. , And then add the external parameter of “government punishment ” to the model. The dynamic simulation shows that: the probability of information sharing varies inversely with the sharing cost and the non-shared benefits alone; with the sharing of excess returns, the separate sharing of benefits and the degree of government punishment Change in the same direction. At the same time, it proved the feasibility of using game theory to study the game problem.
