鉴于能源短缺和环境问题,纳米能源科技备受世界各国关注。本文将纳米能源技术划分为八个领域,基于德温特专利数据库收集了1991-2015年间的纳米能源各领域的专利数据,采用专利计量的方法进行分析,探讨纳米能源各技术领域技术的总体分布、结构分布、时间序列分布、地域分布以及技术热点等。研究发现:纳米能源各领域的技术活动呈现不均衡性发展;中国、美国、日本和韩国是纳米能源各领域技术活动的强国;各领域技术能力分布存在差异且技术热点不同。在未来的发展中,中国应巩固和增强现有的技术优势,实现各领域均衡协调发展。
In view of energy shortages and environmental issues, nano-energy technology has attracted worldwide attention. This paper divides the nano-energy technology into eight areas. Based on the Derwent patent database, it collects patent data from various fields of nano-energy between 1991 and 2015. It analyzes the patents and discusses the overall distribution of technologies in various technical fields of nano-energy. , structure distribution, time series distribution, geographical distribution and technical hot spots. The study found that: The technical activities in various fields of nano-energy are showing uneven development; China, the United States, Japan, and South Korea are strong countries in the field of nano-energy technology activities; there are differences in the distribution of technological capabilities in various fields and different technology hot spots. In the future development, China should consolidate and enhance its existing technological advantages and achieve balanced and coordinated development in all fields.
