摘要:

[目的/意义] 从技术互补性的视角出发,对创新型离群专利和市场成熟型热点专利进行互补研究,发现“创新-成熟”型技术机会,对技术机会识别的研究有重要意义。 [方法/过程] 首先,利用关联规则算法和离群值检测算法对专利分类号进行处理,得到关联性弱、分布边缘化的分类号代表的离群专利以及关联性强、分布中心化的分类号所代表的热点专利。其次,构建时间加权指数和关键词独特性指数来筛选符合双高指数的离群专利作为创新型离群专利;基于专利所处技术生命周期阶段和专利市场价值测度,筛选热点专利作为市场成熟型热点专利。最后,利用两种类型专利的技术关键词构建二维矩阵,通过生成式拓扑映射算法得到技术空白点,将关键词同时来源于两种类型专利的技术空白点作为最终的“创新-成熟”型技术机会。 [结果/结论] 以新能源汽车电池为例进行实证研究,共发现10项技术机会。经与相关政策文件进行内容比对可知,识别结果与该领域的技术现状和发展规划具有较高的一致性,验证了本研究提出的技术机会识别方法的有效性和科学性。

Abstract:

[Purpose/Significance] Starting from the perspective of technological complementarity, this paper proposes a new approach for identifying technological opportunities by comprehensively using outlier patents and hot patents. The fusion analysis of innovative outlier patents and market mature hot patents is carried out to identify "innovation maturity" technological opportunities that combine innovation and maturity, which is of great significance for enriching the theory and methods of technological opportunity identification. [Method/Process] First, based on the "association distribution" characteristics of patent classification numbers, a two-stage method was adopted to screen patents. In the first stage, we used the association rule algorithms to find classification numbers with weak and strong associations, and obtained initial outlier patents and initial hotspot patents. In the second stage, outlier detection algorithms were used to obtain the marginalization classification numbers of the two types of patents in the first stage. Patents containing marginalization classification numbers were selected as the final outlier patents, while patents containing such classification numbers were removed as the final hotspot patents. Second, different methods were adopted for patent screening based on the differences in innovation and maturity of patent content. Using structured and unstructured data from patent databases, we constructed time weighted indicators and keyword uniqueness indicators as the screening indicators for innovative outlier patents. We constructed a technology lifecycle stage discrimination function and patent market value measurement indicators as the screening criteria for mature hot patents in the market. The screened patents were classified into technical fields based on the major categories in the International Patent Classification. Finally, we identified technological opportunities based on technological complementarity. By using the generative topology mapping algorithm to obtain a technical blank point map, the top K keywords in each blank point were obtained, and the sources of the keywords were marked to ensure that new technological opportunities have both good innovation capabilities and mature market prospects. In the future, keyword combinations derived from different types of patents were regarded as "innovation mature" technological opportunities. [Results/Conclusions] Taking the field of new energy vehicle batteries as an example, empirical analysis was conducted to obtain a total of 10 technical opportunities in 5 sub technical fields. Through content comparison with relevant policy texts, 7 technical opportunities showed high consistency. It was found that the identification results were highly consistent with the current technological layout and development direction of the field, indicating that this method has good effectiveness and scientificity in technology opportunity identification, and can provide support for technology prediction and innovation decision-making.
