基于专利分析的中药关键技术发展轨迹

具有稳健性的技术轨迹可以作为研究技术发展和确定最新技术的工具,精准绘制技术发展轨迹有助于推动我国中药产业持续高质量发展。以1987—2018年中国中药行业发明授权专利为数据源,基于专利分析提出一种新的中药产业技术轨迹测绘方法。首先,应用突变级数法将我国中药产业发展划分为4个阶段;其次,构建专利引文网络并应用核心-边缘模型识别各阶段中药行业的核心专利和边缘专利;然后,以核心专利为数据源,采用关键路径算法搜索中药核心关键路径;最后,利用核心专利和边缘专利扩充核心关键路径,进而绘制我国中药产业关键技术发展轨迹。研究结果展示了中药产业的5条关键技术轨迹,实现了中药产业的传承与创新。

Development trajectories of key technologies of traditional Chinese medicine based on patent analysis

Robust technology trajectory can be used as a tool for researching technology development and determining the most emerging and promising inventions. Accurately drawing technology trajectories will help promote the sustainable and high-quality development of traditional Chinese medicine industry. The patents granted for inventions in the Chinese medicine industry from 1987 to 2018 were used as the data source, and a new technology trajectory mapping method for the Chinese medicine industry proposes was based on patent analysis. Firstly, the development of traditional Chinese medicine was divided into four stages by applying the catastrophe progression method; Secondly, the patent citation network was constructed and the core-periphery mode was used to identify the core patents and edge periphery of traditional Chinese medicines in each stage; Then, the core patents were used as data source and the critical path method was used to search the core critical path of traditional Chinese medicine; Finally, the key technology trajectory of traditional Chinese medicine industry was drawn by core patents and periphery patents according to reference relationship. Research results showed the five key technological trajectories of the traditional Chinese medicine industry and realized the inheritance and innovation of traditional Chinese medicine.
