基于共现网络的核心技术领域识别研究

On Identification of the Core Technical Fields Based on Co-occurrence Network

核心技术领域的识别研究能够为相关科研机构以及企业制定技术研发策略和配置研发资源提供决策支持。针对目前核心技术领域测度方法中存在的不足,将"m-核"分析方法引入共现网络的研究中,通过研究特定技术主题下的技术领域共现网络结构特征,测度核心技术领域。以变频技术的专利数据作为数据源,研究结果表明,低压变频技术的核心技术领域为交流电机、家用空调等领域。

For the scientific research institutes and enterprises to decide their technological strategies, the study on the identification of the core technical fields could provide the required theoretical support. Considering the defects of the measuring methods of the core technical fields at present, we apply ＂m-cores＂ analysis to investigate the structure of DMC co-occurrence network under a specific technical topic , and then elect the core technical fields. The experiment based on the patent data of variable frequency technique shows that this new .ap- proach is feasible and reasonable. The results also reveal the core technical fields of the low-voltage variable frequency technique as invol- ving AC motor, household air conditioners, etc.
