摘要
基于中国知识产权网(CNIPR)专利信息服务平台中收录的相关专利信息,运用R语言、Vosviewer和OpenRefine等工具,从数据来源和研究思路方法角度阐明研究方法与数据,分析历年专利申请动向与技术生命周期,专利技术地域分布等内容。针对专利的申请动向、技术生命周期、区域分布等进行可视化分析,得出了反映该领域研究的专利图谱,发现我国装配式建筑技术尚处于技术成长期,应加大研发投入。
The visualization analyses of applied years, technology life cycle and regional distribution are conducted by the use of R language, VOSviewer and OpenRefine based on the patented technology information of fabricated buildings field from China Intellectual Property net. From the perspective of data sources and research methods, the research methods and data are clarified, and the patent application trends and technology life cycle, and the geographical distribution of patent technologies are analyzed. Through these analysis, the patent map of fabricated buildings fields was given. The results show that fabricated buildings technology has stepped into the growth period, and it is necessary to enhance R&D intensity.
