基于演化博弈的农产品供应链信息共享行为研究

运用演化博弈理论,建立了一个农产品供应商和生产加工商的两级供应链的信息共享动态演化博弈模型,并对系统长期的动态演化过程进行分析。结果表明,农产品供应链上各企业进行信息共享的行为与博弈双方的支付矩阵及初始值有关。博弈双方的信息吸收能力、共享量和协同效应系数越大,信息共享概率越大;信息共享成本和风险越大,信息共享概率越小;初始值的增大有利于信息共享,但到一定程度后,各企业会逐渐趋于信息不共享。

Agricultural Supply Chain Information Sharing Behavior Research Based on the Evolutionary Game

A two-stage game model of agricultural supplier and manufacturer supply chain information sharing was established using evolutionary game theory, and long-term dynamic evolution process of the system was analyzed. Results showed that the information sharing behavior of enterprises in the agricultural supply chain was related to the payment matrix and the initial value of the game. The coefficient of the information absorption capacity,the sharing capacity and the co-effect were greater, the probability of information sharing was greater. The cost and the risk were greater, the probability of information sharing was the smaller. The increase of initial value was conducive, but when it come to a certain extent, enterprises would gradually tend to not sharing.
