基于文献计量和专利分析的中美脑机接口领域技术竞争态势比较研究

Comparative Study on the Competitive Situation of Brain-Computer Interface Based on Bibliometrics and Patent Analysis

为探究中美两国脑机接口技术竞争态势以及我国脑机接口技术发展问题,基于文献计量和专利分析方法对两国脑机接口领域的技术竞争态势进行了比较分析,结果显示美国脑机接口领域研发资助机构更加多元,且注重应用导向下的基础研究,我国的资助机构较为单一,主要开展纯基础研究;中国与美国分别侧重脑机接口技术应用研究的不同领域,中国开展脑机接口技术应用研究的创新主体以大学为主,美国则主要包括企业和大学,中国发明专利的申请主要在国内,美国则注重在全球范围内进行专利布局。提升中国脑机接口技术的整体竞争力需要从强化基础研究的应用导向、加强企业创新主体作用、拓展全球专利布局等多方面着手。

In order to explore the competitive situation of brain-computer interface(BCI)between China and the United States,as well as the existing problems of BCI in China,this paper compares and analyzes the technological competition in the field of BCI between the two countries based on bibliometrics and patent analysis.The analysis results indicate that research and development funding institutions in the field of BCI in the United States were more diverse and focused on application-oriented basic research.In China,funding institutions were relatively single,and the main recipients of funding mainly carried out pure basic research.In terms of patent development,China and the United States respectively focused on different fields of research on the application of BCI.Universities were the main innovative entities conducting research on the application of BCI in China,while the United States mainly included enterprises and universities.China's application for invention patents was mainly in domestic,while the United States placed great emphasis on the layout of patents on a global scale.Enhancing the overall competitiveness of China's BCI technology,it is necessary to focus on highlighting the application orientation of basic research,strengthening the role of enterprise innovation entities,and expanding global patent layout.
