摘　　要：识别具有发展潜力的新兴技术和最具价值的新兴技术主体已成为各利益相关方关注的重点。美国的FUSE项目提出了“技术新兴度”这一指标,实现了对新兴技术(主体)的定量评估。在此基础上,本文以专利为研究对象,引入文献计量学、计量经济学等相关方法,在对专利的技术新兴度进行计算的基础上,从定量角度探究专利的技术新兴度与其技术影响力间的关系,并使用纳米载药领域的专利数据进行实证分析。研究表明,专利的技术影响力与其技术新兴度间存在显著的正相关关系,即技术新兴度越高的专利可能对后续的技术发展产生更大的影响和推动作用,且这种新兴技术思想(新兴术语)对专利技术影响力的提高作用具有一定的持久性(至少3年)。本研究为新兴技术的定量研究、高质量专利的挖掘以及我国政府或企业相关科技策略的制定提供了重要的参考。Identifying emerging technologies with development potential and the most valuable emerging technology subjects has become the focus of attention of all stakeholders.In this context,the FUSE project in the United States put forward an indicator of technological emergence,which can be used to measure the technological emerging degree of emerging technologies(subjects)quantitatively.On this basis,present study takes patents which are main carriers of emerging technologies as the research object,and introduces related methods such as bibliometrics,econometrics,etc.,to explore the relationship between the technological emerging degree of the patent and its technological impact from a quantitative perspective.Our research process is mainly divided into three steps:Firstly,we use NLP to extract the candidate terms from the abstract and title of a corpus of abstract records in a technology domain of interest,usually a 10-year period,and then clean and filter them to identify emerging terms and calculate their emergence scores.Secondly,based on the list of term-level emergence scores,we measure the technological emerging degree of a single patent in the target domain in the following three years by the patent-level emergence score.Finally,we quantitatively analyze the relationship between the patent’s technological emerging degree and its technology impact,which is measured by the number of forward citations of the patent.We use patent data in the field of nano drug delivery for empirical analysis.The results show that there is a significant positive correlation between the technological impact of patents and their technological emerging degree,that is,the patent with higher technological emerging degree may have greater influence and promotion on subsequent technological development.Besides,the study also suggests that emerging technological ideas(emerging terms)can improve the technological impact of patents continuously(at least 3 years).Theoretically,firstly,this paper draws on the idea of calculating the subject�
