本研究的目的是通过对日本联合专利网络的分析，找出地区间知识网络的空间结构。本研究调查了位于具有中心性指标的权力节点的区域，并su 2010。结果发现，日本知识网络的空间结构有两种模式，一种是聚集的邻居，另一种是分散在遥远的区域。此外，社区每多有两个权力节点作为网络核心。这些权力节点不仅影响自己的网络，而且影响大范围内的其他社区。而且电源节点几乎都位于市区。这些结果表明知识网络的空间模型正在将区域间的城市系统从传统的等级系统转变为复杂的城市网络系统。
The purpose of this study is to figure out the spatial structure of knowledge network between regions through analysis of joint patent network in Japan. This study investigated regions which are located in power nodes with indicators of centrality, and su 2010. As a result, spatial structure of knowledge network in Japan was found to 2 patterns, one is clustered neighbors and the other is scattered in a distant regions. In addition, communities have each two more power nodes as a core of networks. These power nodes affect their own networks not only same community but also other communities in wide area. Moreover power nodes are almost located in urban area. These results indicate spatial model of knowledge network is transforming urban systems between regions from traditional hierarchical system to complex urban network system.
