摘要

虽然已有许多研究涉及技术路线图结构或路线图绘制方法,但大多数现有方法集中在市场驱动的路线图绘制上。此外,很多研究依赖于定性分析;因此,通过定量分析或系统方法进行的严谨研究较少。因此,本文旨在通过专利引文分析提出一种考虑技术生命周期的新技术路线图方法,这是一种相对稳健的定量分析方法。首先,收集相关技术的专利数据和引文信息。利用这些数据,开发了一个由节点(单个专利)和节点之间的弧线(专利之间的引用链接)组成的专利引用网络。其次,通过考虑专利申请年份和技术生命周期,对所选技术在生命周期中的阶段进行研究。因此,通过估计技术的生命周期来规划技术开发的持续时间。此外,将后续技术分组为某一高级技术的节点,以显示该技术在该时期的演变。最后,通过在技术层中连接这些技术节点并估计开发时间的持续时间,绘制技术路线图。在本文中,为了说明所提出的方法的过程,选择了太阳能相关技术。本文的研究结果可以看作是一种有效利用定量专利数据的技术驱动路径绘制的新方法。

Technology roadmapping based On patent citation network considering technology life cycle
Although there have been many studies conducted that deal with technology roadmap structure or roadmapping methods, most existing approaches concentrate on market-driven roadmapping. Moreover, a lot of the research depends on qualitative analysis; thus, less rigorous research has been conducted through quantitative analysis or systematic approaches. Hence, this paper aims to propose a new technology roadmapping approach considering technology life cycle through patent citation analysis, which is a relatively robust method of quantitative analysis. At first, patent data of relevant technologies and citation information are collected. Using these data, a patent citation network that consists of nodes (individual patents) and arcs between nodes (citation links between patents) is developed. Secondly, a stage of a selected technology in the life cycle is investigated by considering the year of patent application and the life cycle of the technology. Thus, the lifetime of a technology is estimated to plan the duration of technology development. In addition, subsequent technologies are grouped as nodes of a super-level technology to show the evolution of the technology for the period. Finally, a technology roadmap is drawn by connecting these technology nodes in a technology layer and estimating the duration of development time. In this paper, solar energy-related technology is chosen in order to illustrate the process of the proposed method. The results of this paper can be regarded as a novel approach to technology-driven roadmapping that effectively utilizes the quantitative patent data.
