网络社群系统识别、结构特征及位置关系研究——以电子信息材料联合专利网络为例

System Identification,Structural Features and Location Relationship of Network Community——An Example of Combined Patent Network in Electronic Information Materials

从我国电子信息材料行业联合专利网络抱团现象出发,以中国国家知识产权局(SIPO)专利数据库为数据来源,通过G-N算法的模块度指标,动态识别该行业联合专利网络社群结构特征,并从整体层次分析社群的位置关系。结果表明,我国电子信息材料行业存在明显的社群结构;创新网络中的社群结构具有内部连接紧密、外部连接稀疏的特征,在一定时间范围内呈现社群规模和数量保持相对稳定的系统特征;社群在创新网络中扮演着领导人及经纪人角色。通过对联合专利网络社群的剖析,有助于了解企业合作研发行为,同时为网络社群治理和网络权力配置研究提供新视角。

This paper starts from the phenomenon of"clustering"in the joint patent network of electronic information materials industry in China,Using the National Intellectual Property Office(SIPO)Patent Database as a data source,through the modularity index of G-N algorithm,dynamically identify the structural characteristics of the joint patent network community in the industry and analyze the positional relationship of the community from the overall level.The results show that there is an obvious community structure in China's electronic information materials industry;The community structure in the innovation network has the characteristics of tight internal connections and sparse external connections,its system characteristics show that the size and quantity of the community remain relatively stable within a certain time frame;The community acts as a leader and broker in the innovation network.Through the in-depth analysis of the joint patent network community,this paper helps to understand the cooperative research and development behavior of enterprises,at the same time,it provides a new perspective for the research of network community governance and network power allocation.
