煤炭产业寡头动态价格博弈复杂性研究

Research on complexity of coal industry oligopoly dynamic price game

随着煤炭产业供给侧结构性改革,企业经营决策面临着新的挑战。在煤炭产业寡头效应和双渠道供应链快速发展的前提下,为探索煤炭企业的决策之道,分析煤炭产业寡头博弈的复杂特性,建立了双寡头动态价格博弈模型,研究了双渠道供应链动态系统的复杂特性,并分析了服务水平和交付时间对系统均衡解和稳定域的影响。研究结果表明,任一寡头的价格调整变量过大都会使系统进入混沌状态。此外,提高服务水平会缩减自身线下渠道的稳定域,而延长送货时间则会扩大自身线上渠道的稳定域。因此,企业在做决策时,应权衡利润和稳定域,选择合适的调整变量。

With the supply side structural reform of the coal industry,business decision-making is facing new challenges.Under the premise of the oligopoly effect of coal industry and the rapid development of dual channel supply chain,in order to explore the way of decision-making of coal enterprises,the complex characteristics of the oligopoly game in the coal industry are analyzed,a duopoly dynamic price game model is established,the complex characteristics of the dual-channel supply chain dynamic system are studied,and the effects of service levels and delivery times on the system’s equilibrium solution and stability domain are analyzed.The research results show that too large price adjustment variables of any oligarch will make the system enter a chaotic state.In addition,improving service levels will reduce the stability of its own offline channels,while extending delivery time will expand its stability of its online channels.Therefore,when making a decision,an enterprise should weigh the profit and stability domain and choose the appropriate adjustment variables.
