摘要
知识经济背景下,国家间的技术竞争日益激烈,而中国在专利布局方面存在认知与操作短板,制约着中国高新技术产业的发展。因此,提出一套有效的专利布局分析方法,对指导企业进一步实施专利布局具有重要意义。当前,专利布局的分析视角相对局限于企业层面,且传统的布局分析方法不能直观展现企业间的技术攻防意图,所以,本文在刻画产业链专利分布结构的基础上,总结基本的专利分布模式及其蕴含的布局意图,以此实现产业链视角下的专利布局意图挖掘。首先,在微观层面引入结构性与功能性技术关联关系,修正专利知识组织结构,并根据修正后的专利知识图谱本体构建领域专利知识图谱;然后,利用图嵌入算法刻画产业链专利分布结构;接着,总结5种基本的专利分布模式并分析其布局意图,基于此挖掘产业链各布局主体的布局意图;最后,通过在非全氟化质子交换膜领域进行实证研究,验证了上述方法的有效性与实用性,并为我国非全氟化质子交换膜企业以及产业的安全发展提出了应对建议。
In the background of the knowledge economy,technological competition among countries is becoming increasingly fierce.However,there are cognitive and operational weaknesses in China’s patent layout,which restrict the development of China’s high-tech industry.Therefore,it is of great significance to propose a set of effective patent layout analysis methods to guide enterprises in further implementing such layouts.Currently,the analysis perspective of patent layouts is limited to the enterprise level,and the traditional layout analysis methods cannot directly show the technological attackand-defense intention between enterprises.Based on the description of patent distribution structure of the industrial chain,this study summarizes the basic patent distribution pattern and its layout intention to realize its mining from the perspective of the industrial chain.This study first modified the organizational structure of patent knowledge by introducing the structural and functional associations at the micro level,and the domain patent knowledge map was then constructed according to the revised Patent Knowledge Map ontology.Next,we used a graph embedding algorithm to describe the patent distribution structure of the industry chain.We then summarized five basic patent distribution patterns and analyzed their layout intention,based on which we mined the layout intention of each layout subject in the industrial chain.Finally,through empirical research in the field of non-perfluorinated proton exchange membrane,we verified the effectiveness and practicability of the above method,and provided suggestions for the safe development of China’s non-perfluorinated proton exchange membrane industry.
