北京市产业关联网络演变研究
The Evolution of Beijing's Industry Association Network
摘要
Abstract
By constructing a Beijing industry association network model based on complex network theory and statistical data,this study analyzes the inner meaning of topological characteristics and community structure change by calculating and comparing topological characteristics of Beijing industry association network in 2002,2005,2007,2010 and 2012.The study reveals several findings.First,industry association network of Beijing shows a tendency of sparsification,and the number of edges between nodes are decreasing and so is the network density.Second,industries of the highest forward correlation degree has shifted from information transmission,software and information technology service industry to water production and supply,transportation,warehousing and postal service industry,and then to the production and supply of electricity and heat industry.This indicates that the engine of the economic growth of Beijing is upgrading.Third,the average degree and ring correlation degree of Beijing industry association network displays an inverted "V"-type change and the ring structure a tendency of sparsification,which indicates that Beijing has developed a stable exportoriented economic structure.The study concludes with four suggestions:first,the government should continue to strengthen the advantageous position of the cultural creative industry and productive service industry to exercise their pivotal role in industry association network;second,greater efforts should be exerted on marginalized industry in the network for industrial transfer;third,energy management should be strengthened to improve industry energy efficiency;lastly,industrial clusters should seek for breakthrough and form innovative clusters.关键词
