基于Logistic模型的产业树演化机制研究

Study on Evolutionary Mechanism of Industry Tree Based on Logistic Model

通过建立基于Logistic模型的产业树演化模型,从产业树初始形成演化阶段和产业树成长演化阶段两个层面对产业树的演化过程和结果进行演绎分析,得出了完全取代型演化、部分取代型演化和竞合型演化三种不同的产业树演化过程和演化结果,摸清了产业树演化过程及演化机理,为产业树在产业链延伸、产业结构优化和产业转型升级等方面的应用奠定了理论基础.

Through the establishment of an industrial tree evolution model based on the Logistic model, the evolution process and results of the industry tree are deduced from the initial formation phase and the evolution phase of the industry tree, and a complete substi tution evolution , partial substitution and co-occurrence evolution is obtained. The evolution results have made it clear that the evolution process and evolution mechanism of industrial trees have laid a foundation for the application of industrial trees in industrial chain extension, industrial structure optimization and industrial transformation and upgrading.
