创意产业经济网络的分析与决策——基于有向节点赋权网络的测度方法

Analysis and Decision-making of Economical Network in Creative Industry——Based on Node General Measurement in Directed Network

在创意产业等产业经济网络中,其决策分析需要对有向网络主体重要性进行定量测度。综合测度法给出了节点赋权网络中节点重要性的测度方法。但是没有考虑权值交易衰减的变化和路径的有向性,不适用于实际情形常见的有向网络。文章根据节点删除思想提出全面测度法,以易行有效的方法定量测度有向网络中节点的重要性,为创意产业的开发与建设提供决策支持,最后以典型创意产业为例给出其应用。

In economic network of industry-chain, just as Creative Industry, deeision-making and analysis are based on the measurement of the importance of the nodes. Using Comprehensive Importance Measurement （CIM）, importanee of nodes within an undireeted network has been calculated, but the directed edges and the attenuation of weight trading are ignored, so no measurement has been applied to the directed network. On the basis of the approach of deleting a node and CIM, this paper shows applicable measurement for the importanee of a node within a directed network, which is modeled denominated General Importanee Measurement （GIM）. Finally, A ease of ereative industry will be presented to illustrate the application of GIM.
