基于专利数据的全球氢能产业技术创新态势分析与我国发展对策研究

Innovation Trends of Global Hydrogen Energy Industry and Development Strategies in China Based on Patent Data

氢作为一种高效清洁的能源和理想的能源转化媒介,可以广泛应用于工业、交通、电力等领域,助力能源绿色低碳转型。本文基于专利信息分析,面向氢能技术开展创新态势研究,为今后氢能领域的专利研究和产业规划提供参考依据。研究发现,全球氢能技术创新处于持续活跃的时期,中国在其中发挥着越来越重要的作用,但是创新主体中心化明显。进一步通过技术构成、相对技术优势指数、技术领域发展速率指数等研究方法比较氢能技术创新态势,在此基础上提出我国加快氢能产业链全面布局规划,强化企业创新主体地位,推进氢能产业规模化发展的建议。

Hydrogen energy,as an efficient and clean energy and ideal energy conversion medium,can be widely used in industry,transportation,power and other fields to promote the green-oriented transition and innovation development of energy.This article analyzes the overall development trends of hydrogen energy technology from the perspective of patent analysis,and provides a reference for the further patent research and industrial development in the field of hydrogen energy.The global technology innovation of hydrogen energy is continuously active,in which China plays an increasingly important role,but the top patent applicants are obviously centralized in China.Furthermore,this article compares the hydrogen energy patents from the aspects of technology distribution,revealed technology comparative advantage and relative growth rate percent.On these basis,the study suggests that China should accelerate the layout of the entire hydrogen energy industry chain,strengthen the dominant position of enterprises in scientific and technological innovation and scale up the development of hydrogen energy industry.
