Competition on Resources Input from Industry Sectors Based on Co-citation Network Analysis

Abstract

This paper made use of Beijing‘s input-output direct consumption coefficient from 2002 to 2012 to build weighted undirected networks based on co-citation algorithm which name Industrial Need-Competition Network. 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.
