摘　　要：关键共性技术识别影响政府在不确定性市场环境中的资源投入及企业研发方向,制约制造业发展。如何准确识别关键共性技术是政府和企业急需解决的问题。本研究基于专利数据及LDA主题模型,提取隐含技术主题,选取高强度技术主题为研究对象,以技术共现率评估技术主题通用性,结合技术主题活跃度、效益性及关联性,识别共性技术。在此基础上,借鉴社会网络分析方法,以技术主题为节点,技术主题共现强度为边权,量化技术主题权利,筛选关键节点,识别关键共性技术。并以新材料领域为例进行研究,结果显示高性能铝合金制备、纳米粉末及其薄膜制备工艺、金属粉末的制备及应用、高强度高硬度陶瓷模具制备是新材料领域的关键共性技术。The identification of key generic technology affects the resources provided by the government to uncertain market environments and the direction of enterprise research,restricting the development of the manufacturing industry.How to accurately identify key generic technology is an urgent problem for governments and enterprises.Based on the patent data and LDA theme model,the themes of implicit technology are extracted,the high-intensity technology topics are selected as research objects,the technology co-occurrence ratio versatility is analyzed,and the technical theme activity as well as value are combined to identify generic technology topics.Using social network analysis methods,technology topics are considered as nodes and technology theme co-occurrence intensity as edge weights;further,the technical subject rights are quantified,key nodes are screened,and key generic technology is identified.Finally,considering the new material field as an example,the results demonstrate that the preparation of high property aluminum alloys,nano powder,films,and high strength and hardness ceramic mold as well as the preparation and application of metal powder are realized by employing key generic technology in the field of new material.
