摘要
为了分析产品技术溢出对同质产品制造商带来的影响,研究了不同市场占比的双寡头企业之间的竞争,考虑到企业参股对供应链决策的竞争问题,构建了Cournot-Bertrand模型,利用逆向归纳法求解动态博弈下双寡头供应链企业决策行为,通过稳定域、二维分岔图以及最大李雅普诺夫指数、时间序列进一步讨论了该模型,比较不同参数对供应链价格、产量和利润的影响。结果表明:企业选择稳定的溢出效应有利于供应链发展,合理的参股比例促进供应链利润达到最优值;动态系统随着调整参数的不断变化,呈现出分岔、混沌和多重稳定性。拓展了复杂系统理论在双寡头供应链中的应用,也为企业制定相应策略、帮助寡头供应链实现可持续发展目标提供理论指导。
In order to analyze the impact of product technology spillovers on homogeneous product manufacturers,study the competition between duopoly enterprises with different market shares,and take into account the competition of enterprises’equity participation on supply chain decision-making,a Cournot Bertrand model is constructed,and backward induction is used to solve the decision-making behavior of duopoly supply chain enterprises under dynamic game.The time series further discussed the model and compared the effects of different parameters on supply chain prices,production,and profits.The results indicate that choosing a stable spillover effect is beneficial for the development of the supply chain,and a reasonable shareholding ratio promotes the optimal value of supply chain profits.The complex impact of adjusting parameters on the power system was studied.The dynamic system exhibits bifurcation,chaos,and multiple stability as the parameters are constantly adjusted.This study expands the application of complex system theory in duopoly supply chains and provides theoretical guidance for enterprises to develop corresponding strategies.
