| 中文摘要: |
| 基于定量分析识别技术前沿并测度各国的技术差距具有重要的理论和现实意义。本研究初步探讨了基于专
利数据，利用文献计量学的引文耦合分析法，进行技术前沿的识别和技术差距粗略测度，并以锂离子电池为例进行实
证研究。研究结果表明，该方法所识别出来的中国、美国和日本在锂离子电池领域的技术前沿以及各国之间的技术差
距，与产业现状具有一定一致性，是一条可行的研究途径。 |
| 英文摘要: |
| Recognition of technical fronts as well as measure of technical gaps among countries based on
quantitative analysis has important theoretical and practical significances. In this paper, a new method for
identifying technical fronts and measuring technical gaps roughly in terms of bibliographic coupling analysis
based on patent data is discussed, and the field of Lithium-ion battery is selected to perform empirical analysis.
Results show that technical fronts for Japan, the USA, and China, as well as technical gaps among them
recognized according to the method above is in accordance with industrial status. So the method used in this
paper is an effective and feasible approach. |
