生态工业链中企业间合作关系的演化博弈分析

Evolutionary Game Analysis of Cooperative Relationships among Enterprises in Eco-Industrial Chain

针对生态工业链中生产者企业、消费者企业和分解者企业所掌握信息的不对称性,以及追求各自利益最大化所导致的各类企业间长期持续博弈的现状,文章以三类企业群体为博弈主体,基于博弈主体有限理性和有限信息假设,建立三方合作关系的演化博弈模型和复制动态方程,并分析其演化稳定策略和演化影响因素。结果表明:企业群体间的长期均衡受博弈发生的初始状态和构成博弈主体支付的贴现因子、超额利润总额及各类企业为合作所付出的初始成本的影响。详细分析了丹麦卡伦堡生态工业园中企业间的合作关系的演化过程,验证了分析结果的正确性。

Aiming at the current situation that the asymmetry of information possessed by producer enterprise,consumer enterprise and decomposer enterprise in eco-industrial chain and the pursuit of maximizing their own benefits cause the long-term continuous game among various enterprises,taking the three kinds of enterprise groups as game subjects,and under their bounded rationality and limited information hypotheses,the evolutionary game model and the replicated dynamic equation about their cooperative relationships are established in this paper.The evolutionary stable strategies and the evolutionary influence factors are investigated.The results indicate that the long-term equilibrium of enterprise groups is influenced by the initial state of game occurring and the discount factors constituting the payoff of game subjects,the total excess profit as well as initial costs for cooperation paid by various enterprises.On this basis,the evolutionary process of cooperative relationships on enterprises in Kalun-borg Eco-industrial Park is examined and the correctness of the above analysis is verified.
