竞争对手识别的三种专利引文分析方法研究——以全息摄影技术为例

Research of Three Patent Citation Analysis Methods to Identity the Competitors:An Application to Holography Research

高被引分析方法经常被运用于竞争对手识别中,但高被引分析方法阈值难以确定。本文尝试通过关键技术路径方法和专利引证地图法识别全息摄影技术领域中的竞争对手及竞争对手格局,从理论分析和实证研究上分析高被引分析方法、关键技术路径方法和专利引证地图法识别竞争对手的不同和各自的局限,并探讨将这三种方法相结合进行竞争对手识别和分析的可行性。

High cited analysis method is usually used in identifying the competitors;however it is hard to determine its threshold.This paper attempts to use critical path method and patent citation map to identify competitors and competitive positions in the technology field of holography.The paper attempts to theoretically and empirically analyze the differences and limits of competitors identifying by the three methods of high cited method,CPM and patent citation map.The feasibility of combining these three methods to identify competitors and analyze their competitive positions is also discussed.
