基于演化博弈的企业价值链协同知识创新研究

Evolutionary Game Analysis of Collaboration Knowledge Creation in Enterprise Value Chain

针对企业价值链知识创新的协同问题,考虑到有限理性的成员可能采取两种不同策略,运用演化博弈方法进行建模分析。通过构建动态复制方程、复制相位图,理论推导以及数值模拟,探讨最终可能存在的稳定策略。结果表明:随着研发总成本的减少、超额收益的增加;单独协同方额外收益的增加、不协同方背叛收益的减少,企业价值链协同知识创新朝帕累托最优方向发展的概率将增加。

For collaboration knowledge creation in enterprise value chain, this paper considered the bounded rationality mem- bers in enterprise value chain are likely to adopt two different strategies with using the evolutionary game theory model to analysis. It constructed the replicator dynamics equation, replication phase diagram and adopts theoretical derivation, numerical simulation to discuss the eventually possible existing stable strategies. Result showed that the probability toward Pareto optimal of collaboration knowledge creation in enterprise value chain would increase with the inereasion of excess retuns, the reduction of total cost of R＆D, and the enhancement of singal synergy side extraneous returns, the descendment of nonsvnerav side betrayed returns.
