摘要
构建并度量客户—供应商网络对管理学和产业组织学的研究具有重要意义。由于缺乏相关技术的支持,管理学一些领域的研究尚停留在理论阶段,缺乏实证支持。本文通过引入图论和社会网络的相关技术,以中国国家统计局提供的投入产出表数据为基础,介绍了构建行业层面的客户—供应商网络的方法。鉴于复杂网络的相关指标难以进行手工度量,本文介绍了采用Matlab软件计算网络集群系数和平均最短路径的程序和方法,为后续实证研究奠定了基础。
Constructing and characterizing a customer-supplier network has a great significance for the researches on management science and industrial organization. However, due to the lack of relative technical support, the research of related fields in management remains a theoretical target and lack of empirical support. By introducing graph theory and relative technology of social network and based on the data of input-output table provided by National Bureau of Statistics, this paper introduces a way to build the customer-supplier network at the industrial level. As it is difficult to manually measure the relative index of complex network, this paper describes a procedure and ways to calculate the computer network clustering coefficient and the average shortest path length by using Matlab, laying a basis for future studies.
