投入产出表数据描述了区域经济系统中各产品部门间经济技术关联紧密程度,其基本流量表矩阵形式可作为复杂网络邻接矩阵,从而形成有向加权网络.依据投入产出表直接消耗系数矩阵构建京津冀三地及整体产业信息传递网络模型,通过平均资源分配法挖掘产业部门间的资源竞争关系,并构建产业竞争网络模型,引入点权分析京津冀区域现代制造业竞争状态,最终提出促进京津冀现代制造业协同发展的相关建议.%The input-output table data describe the degree of economic and technological correlation between the product de-partments in the regional economic system. The matrix form of the basic flow table can be used as a adjacency matrix of complex networks to form a directional weighted network. Based on the direct consumption coefficient matrix of input-out-put table, this paper constructs the industrial information transmission network model of Beijing-Tianjin-Hebei and the whole industry, and then excavates the resource competition relationship between the industrial departments through the average resource allocation method and constructs the industrial competition network model, The author analyzes the com-petition state of modern manufacturing industry in Beijing, Tianjin and Hebei region and puts forward some suggestions to promote the coordinated development of modern manufacturing industry in Beijing, Tianjin and Hebei.
