摘要
根据2002—2012年北京市投入产出的直接消耗系数,结合共引网络的建模思想,构建一类加权无向网络——产业需求竞争网络,并引入边权、单位权和差异性作为衡量网络中竞争关系的指标。通过研究发现:INCN-BJ网络的边权反映了产业链环节的完善程度,单位权反映了产品部门对产业系统的促进作用,差异性则区分出产业系统中需要加大产业政策指导的落后产品部门。
This paper made use of Beijing ‘s input-output direct consumption coefficient from 2002 to 2012 to build a sort of weighted undirected networks which were named Industrial Need-Competition Network based on co-citation algorithm. Then edge weight,unit weight and disparity in the weight were chosen to analyze competition relationship contained in the whole network. As results,edge weight reflects the extent to improve the industrial chain links,unit weight reflects the role in promoting industrial system,and disparity in the weight can be used to distinguish backward industries needing policy guidance from governments.
