摘要
不同国家或地区经济系统中各产品部门之间的经济技术关联程度能够用投入产出表数据进行描述,且数据均能以矩阵形式呈现,通过直接或间接处理后可以作为复杂网络的邻接矩阵,进而形成一类有向加权网络。根据国家间投入产出数据构建了全球强关系网络,然后进一步选取特定产品部门为核心产品部门构建了全球产业集群发展关联网络,并采用加权集聚系数研究核心产品部门在经济系统中的作用和地位。
The degree of correlation between the various economic and technical products division between different countries or areas in economic system can use the input-output table to describe the data,and the data can be presented in the form of matrix,by directly or indirectly after treatment can be used as the adjacency matrix of complex networks,and then formed a kind of weighted network to some.According to the national input-output data and construct the globe industrial strongest relevant networks,and then select the specific product and construct the global industrial cluster development network as the core department.In the end using the weighted coefficient,will research the function and status of automobile manufacturing industry as the core product department in economics systems.
