摘　　要：基于投入产出与复杂网络理论构建产业关联网络模型,利用2002~2010年投入产出数据构建四个时间节点的产业关联网络,发现产业关联网络的小世界特性,即多数产业部门之间通过一个产业即可发现投入产出关联。通过度、中间中心性以及关联度等指标对产业关联网络脆弱性进行分析发现,多数产业的度数小于平均度数,度数较大的产业主要集中在化学工业、电力热力的生产和供应业以及交通运输业等基础产业,而且这些产业多处于网络的核心位置,对其他产业有较强的控制作用,如果发生问题,危机更容易波及整个网络,但这些产业之间对于去掉一些链路不敏感,相互之间的关系比较稳健。Using input - output theory and complex network theory, the authors builds industrial associated network model and uses input - output data during 2002 and 2010 to build four year＇ s industrial associated networks, then finds industri- al network has small -world property so that input -output relevancy between most industrial sectors can be found by one industry. By degree, betweenness centrality, correlation degree and other indexes, the paper analyses vulnerability of in- dustrial associated network and finds that degrees of most industries are less than average degrees. The industries with large degree concentrate on chemical industry, electricity, heat production and supply industry, transportation industry and other basic industries located in core position and have strong control effect on other industries. If the network has problem, the crisis may sweep the entire network. These industries are not sensitive to put off some links and the relationships between them are robust.
