【摘要】：利用复杂网络理论和历史数据构建北京市产业关联网络模型,计算和比较2002、2005、2007、2010、2012年北京市产业关联网络的演变情况,分析其拓扑特征和社团结构演变的内在涵义。研究发现:北京市产业关联网络呈现出稀疏化的发展态势,节点之间的连边数量不断减少,网络密度逐步降低;前向关联程度最大的产业从信息传输、软件和信息技术服务业转变为水的生产和供应、交通运输仓储和邮政业,再转变为电力热力的生产和供应业,说明北京经济增长引擎不断升级;北京市产业关联网络的平均度和环向关联度都呈现出倒"V"型变化,环向结构越来越稀疏,这说明北京已经形成了稳定的外向型经济结构。根据研究结论,建议北京市产业发展应继续加强文化创意产业与生产性服务业在产业关联网络中的优势地位,发挥其在产业关联网络中的信号枢纽作用;对于处在产业关联网络边缘的产业应加大产业转移力度;加强能源管理,提升行业能源使用效率;产业集群应积极谋求向上突破,形成创新集群。
[Abstract]:Based on the complex network theory and historical data, this paper constructs the Beijing industry related network model, calculates and compares 2002 / 05 / 2007 / 2010. In 2012, the evolution of Beijing industrial association network was analyzed, and its topological characteristics and the inherent meaning of the evolution of community structure were analyzed. It was found that the industrial related network of Beijing showed a sparse trend of development. The number of connected edges between nodes is decreasing and the network density is gradually decreasing. The industry with the greatest forward correlation has shifted from information transmission, software and information technology services to water production and supply, transportation, warehousing and post office, and then to electricity and heat production and supply. This shows that the engine of economic growth in Beijing is constantly upgraded; The average degree and circumferential correlation degree of Beijing industrial connection network both show inverted "V" type changes, and the ring structure is becoming more and more sparse, which indicates that Beijing has formed a stable export-oriented economic structure. According to the conclusion of the study. It is suggested that the industrial development of Beijing should continue to strengthen the dominant position of cultural and creative industries and producer services in the industrial connection network, and give play to its role as a signal hub in the industrial related network. For the industry on the edge of the industrial network, we should increase the intensity of industrial transfer; Strengthen the energy management, improve the efficiency of energy use in the industry; Industrial clusters should actively seek upward breakthroughs to form innovative clusters.

【正文快照】： 一、引言产业关联是指国民经济中各产业之间存在的广泛的、复杂的和密切的技术经济联系。这种联系以产业间的投入与产出、供给与需求的数量关系为主要内容,反映了各产业间“量”的关系。各个产业在中间生产过程中相互影响、相互制约,构成了一个动态系统。分析这一动态系统内部
