作为一个开放的、非线性并且远离平衡态的自组织系统,煤炭产业链在促进煤炭深加工、伴生资源的综合利用和实现煤炭产品附加值的提升方面具有重要作用.通过引入Logistic模型,建立产业链间具有差异性影响系数的煤炭产业链系统演化模型,通过分析各自演化方程组的特征矩阵及特征根,得出了完全独立、完全竞争、部分竞争共存以及部分竞争取代等4种不同的产业链系统演化形态.从而从系统演化的角度研究出了煤炭产业链系统的演化过程及相应机理,对于促进不同形态的煤炭产业链的健康发展具有重要的理论和现实意义.
As an open, non-linear and far from equilibrium self-organization system, the coal industry chain plays an important role in promoting the deep processing of coal, comprehensive utilization of associated resources and increasing the added value of coal products. By introducing Logistic model, Through analyzing the eigenvalues and eigenvalues of their respective evolution equations, four different industrial chains are obtained: complete independence, complete competition, co-existence of partial competition, partial substitution of competition, and so on. System evolvement.From the perspective of system evolution, the evolution process and corresponding mechanism of coal industry chain system are studied, which has important theoretical and practical significance for promoting the healthy development of different forms of coal industry chain.
