Abstract：According to the actual situation of oligarchs price game in Chinese insurance market, we innovation to considering the influence of profit and market share factors to the oligarchs decision-making synthetically, and have the further consideration on the impacts of different price adjustment speed and the different scales of delay strategies on the game process. And then established the corresponding three oligarchs' price game model with the operation of insurance market, have the analysis to the characteristics of the system's complexity by using nonlinear dynamic system theory, then probe into its complexity evolution trend characteristics. Finally, have the corresponding economic and management sense analysis of the system according to the Lyapunov exponent figure and strange attractor. Through the numerical simulation, confirmed the accuracy of the results. The research conclusion has good guidance meaning for insurance market to keep benign competitive situation and the determination of the game price.

摘要：根据中国保险市场寡头价格博弈的实际情况，创新性地综合考虑了利润和市场占有率因素对寡头决策的影响，及不同的价格调整速度和不同尺度的延迟策略对博弈价格的影响程度。进而建立了相应的市场运行三寡头价格博弈模型，运用非线性动力系统理论对系统的复杂性特征进行分析，探究其复杂性演化趋势特征。最后根据所得到的系统的Lyapunov指数图谱及奇异吸引子对系统进行了相应的经济和管理意义上的剖析。通过数值模拟，证实了结果的准确性，研究结论对保险市场的保持良性竞争态势及博弈价格的确定具有较好的指导意义。
