中文摘要：
企业间技术相似性是企业技术情报分析的重要内容。为了给企业在全球范围内寻求技术竞争与合作对象提供有效的决策信息支持，提出基于专利耦合的企业间技术相似性分析方法与流程。首先，综合比较了目前理论研究中的相关方法，指出专利耦合分析能较为准确、实时地体现出企业间的技术相似性。然后，在阐释专利耦合分析基本原理的基础上，对企业间专利耦合强度的计算方法进行改进，以便有效区分多对耦合对象之间耦合强度的差异。再将专利耦合分析与相关分析及多维尺度分析相结合，构建了企业间技术相似性可视化分析与应用流程框架。最后，以平板显示技术领域为例论证了基于专利耦合的企业间技术相似性可视化分析流程与应用效果，为企业相关技术情报分析实践提供参考。
英文摘要：
The technological similarity among enterprises is an important content of enterprises＇ technological intelligence analysis. Approach and process for technological similarity analysis for enterprises based on patent coupling is raised, in order to supply enterprises with effective decision - making information and help enterprises to search for technology competitive and cooperative objects world- wide. First, this paper compares some relate approaches in previous studies and points out that patent coupling analysis is a more accu- rate and real - time approach for reflecting technological similarity among enterprises. Secondly, the paper improves the method for cal- culating the coupling strength of the paired enterprises based on elaborating the principles of patent coupling analysis, in order to effec- tively distinguish the difference of coupling strength among several coupling pairs. Thirdly, the paper constructs a visualization and ap- plication process framework for analyzing technological similarity among enterprises, through applying correlation analysis and multiple - dimension sealing based on the coupling data. Finally, this paper reveals the technological similarity among the primary organizations in the field of flat panel display, it further demonstrates the visual analysis and application process of enterprises＇ technological similarity analysis based on patent coupling and can provide a guide for enterprises＇ technology intelligence analysis.
