基于熵权-TOPSIS-德尔菲法的核心技术识别研究--以芯片产业技术为例

Research on Core Technology Identification Based on Entropy-Topsis-Delphi Method:A Case Study of Chip Industry Technology

[研究目的]我国在芯片产业领域仍存在核心技术受制于人的现象,但国内关于芯片领域核心技术识别的文献较少。识别该领域的核心技术并分析其发展现状有助于我国芯片技术实现自立自强。[研究方法]构建涵盖“技术-市场-法律”三维度的核心专利评价指标体系,应用基于熵权-TOPSIS-德尔菲法的核心技术识别模型对大为(Innojoy)专利数据库检索到的1985年以来芯片制造领域专利数据进行核心技术识别。[研究结论]最终识别到32件芯片制造领域的核心技术,其中31件为美国持有,技术领域主要集中在生物医药、半导体元器件、数据存储和通信传输技术几个领域。从专利申请时间看,核心技术布局已逐渐由通信及数据存储领域演变到了生物医药领域,当前美国在生物医药领域的芯片专利布局非常前瞻。

[Research purpose]There is still the phenomenon of core technology being controlled by others in the field of chip industry in China,but there are few literatures about core technology identification in the field of chip industry in China.Identifying the core technologies in this field and analyzing their development status will help our chip technology to achieve self-reliance.[Research method]A core patent evaluation index system covering three dimensions of"technology-market-law"was constructed,and the model based on Entropy-TOPSIS-Delphi method was used to identify the core technology in the chip manufacturing patent data retrieved from Innojoy patent database since 1985.[Research conclusion]In the end,32 pieces of core chip manufacturing technologies were identified,31 of which were held by the United States.The technology fields mainly focused on biomedicine,semiconductor components,data storage and communication transmission technology.From the perspective of patent application time,the layout of core technologies has gradually evolved from communication and data storage to biomedical field.Currently,the chip patent layout in biomedical field in the United States is very forward-looking.
