摘要
本文利用数学中的序关系建立了产业结构的偏序模型,在此基础上提出了如下产业概念的严格数学刻画:产业链、产业链长度、产业的出度与入度,给出了基础产业与重要产业的数学定义。最后,根据本文的研究结论,提出了产业发展的三点启示。为在数理层次上进行产业结构研究提供了一个新的方向。
This thesis sets up a partial order model of industrial structure by using order relation in mathematics.And on this basis,it proposes a serious mathematic description on the concepts of Industry： Industrial chain,length of industrial chain,out-degree and in-degree of industry.And it gives mathematical definition of basic industry and important industry.In the end,according to the research conclusion,the thesis proposes three revelations about development of industry,which provides a new direction on the mathematical hierarchy research of industrial structure.
