基于演化博弈的港口竞合策略选择及仿真研究

Research on the Selection and Simulation of Port Co-operation Strateg Based on Evolutionary Game Theory

基于有限理性、不完全信息假设,运用竞合博弈和演化博弈理论探究港口竞合行为策略选择的内在机理和长期演变规律。构建了港口竞合博弈双层规划模型,运用shapely值对合作联盟的收益进行分配;引入"收益分配系数"、"合作成本"、"违约增量收益"、"违约补偿金"等参数构造港口博弈非对称得益矩阵,在此基础上建立演化博弈模型,对港口演化博弈均衡点的稳定性进行分析,并通过MATLAB R2010b对港口竞合演化路径的进行仿真。研究结论表明:演化稳定均衡点以及演化路径受初始状态选择、"合作收益增量"、"收益分配系数"、"合作成本"、"违约收益"、"违约补偿金"等参数影响。最后,针对演化影响参数提出使双方合作成为唯一进化稳定均衡的措施建议,确保港口协作发展。

Taking evolutionary game theory and cooperation-competition game theory as the main theoretical instrument,the choice of competition or cooperation of port was studied based on bounded rationality and hypothesis of incomplete information.The bi-level modelofport competition or cooperation model was constructed,and the income distribution of the cooperative alliance was distributed by the shapely value;the parameters such as“income distribution coefficient”,“cooperative cost”,“incremental incremental income”and“default compensation”were introduced into the evolutionary game model which was established to analyze the stability of the equilibrium point of the evolution of the port,and the simulation analysis of the evolution path of the port competition was carried out by MATLAB R2010b.The results show that the evolutionary equilibrium and the evolution path are affected by the initial state selection,the“incremental income of cooperation”,“income distribution coefficient”,“cooperation cost”,“default income”and“default compensation”.Finally,the countermeasures for the stability of port cooperation was put forward so that the cooperation will become the only evolutionary and stable balance to ensure the coordinated development of the port.
