基于专利的建筑节能技术领域发展研究

The development research of building energy efficiency based on bibliometric analysis

基于德温特数据库收录的近10年建筑节能领域专利数据进行计量分析,从发展趋势、区域分布、目标市场布局、重点技术领域和主要专利权人等角度分析了全球建筑节能领域发展现状。研究发现全球建筑节能专利申请数量逐年上升,供暖和空调系统、太阳能利用是近10年全球研究热点;中国、美国、日本是目前全球建筑节能领域专利数量较多的国家,但中国相关技术多处于研发阶段,商业化程度有待加强。最后本研究结合发达国家的先进做法,对中国建筑节能领域发展提出建议。

Based on the Derwent patent data of building energy efficiency in the past ten years, the latest development status of global building energy efficiency is analyzed accoding to the development trends, regional distribution, target market layout, key technical fields and major patentees. The research indicates that the patent number of building energy efficiency in the world has gradually increased;space heating and air conditioning systems and solar energy utilization have been the focus of global research for nearly ten years;China, the United States and Japan arecurrently the countries with a large number of patents in the field of building energy efficiency in the world. China is mostly in the research and development stage with the low degree of commercialization. Finally, combined with the advanced practices of developed countries, this study puts forward recommendations on the development of China’s building energy efficiency.
