加权超网络视角下生态产业结构演进研究

Evolution of Eco-Industrial Structure from a Perspective of Weighted Supernetwork

如何从促进生态文明建设的产业结构演进过程中把握其动力机制,揭示其内在机理和演进趋势是当前产业结构研究的热点问题。针对产业及其动力因素所形成的复杂系统所具有的多维性、多层性和多属性特点,运用超网络工具构建了"产品—技术—资源"超网络。经分析表明,演进的内在机理在于技术知识和资源信息在超网络中的流动。进而提出了技术和资源对产业结构演进的贡献广度和贡献深度以及产业结构演进对技术资源的需求广度和需求深度,分别实现了对超网络中三层网络的加权,并运用该网络分析了生态产业结构演进的新趋势。

These are hot issues in current studies on how to grasp dynamic mechanism ,to promulgate internal mechanism and to analyze evolution trends in the evolution of industrial structure so as to promote the construc-tion of ecological civilization .Aiming at the characteristics of multi-dimensions ,multi-layers ,and multi-attrib-utes in the complex system made up of industries and their dynamic factors ,this paper constructs the supernet-work model of “products-technologies-resources” .The results show that inner mechanism of evolution of in-dustrial structure is the flow of technical knowledge and resource information .Then ,the concepts of contribu-tion breadth ,contribution depth ,demand breadth and demand depth are proposed .Furthermore ,the three networks in supernetwork are weighted respectively .Finally ,the new evolution trends of the eco-industrial structure are analyzed by applying the weighted supernetwork .
