基于复杂社会网络分析的产品部门中间人属性研究

摘要

论文根据北京市近年来的投入产出数据，结合图论建模理论构建了产业结构网络模型。然后，通过对经典的Floyd路径搜索算法进行改进，得到了衡量产业部门之间强关联程度的网络模型，称之为产业间最强关联网络。在此基础上，论文结合社会网络分析范式，对产品部门和网络整体的中间人属性进行了研究，从协调属性、中介属性、内联属性、外联属性和联络属性等5个方面分析了产业系统内部产业链的联接状况和紧密程度。%In this paper input -output basic matrix of Beijing was made use of to build a sort of directed and weighted network named Industrial Structure Network based on the theory of complex networks .Then , an improved Floyd algorithm was chosen to form a kind of sub-network which reflected strong association among industrial sector and was named Industrial Strongest Relevant Networks .Fi-nally ,according to social network analysis ,the brokerage roles of each industrial sectors and the entire structure were divided into 5 sorts in order to research cohesion degree of industry chain ,which respectively function as coordinator ,broker ,gatekeeper ,representative and liaison .
