Technological Innovation and the Development of the Fuel Cell Electric Vehicle Industry Based on Patent Value Analysis
Currently, major economies are competing on the technological and industrial development of fuel cell electric vehicles (FCEVs). This paper discusses the relationship between the patent value of FCEVs and the commercialisation of this technology. First, the patent data of FCEVs are analysed, focusing on data of China, Germany, Japan, the Republic of Korea, and the United States. Then, the paper constructs the FCEV patent value index framework based on the technological value and economic value of patents. Finally, this paper conducts an empirical study to analyse the influence of patent value on the development of the FCEV industry. It is found that, under the current situation, individual patent value can significantly promote the development of the FCEV industry, whilst the gross patent value of a certain country even has a negative impact. In addition, the increase of hydrogen infrastructure, research and development expenditure, and market demand will significantly promote the development of the FCEV industry. The development level of related industries such as the battery electric vehicle industry and the reduction of environmental pollution are also significant drivers of the development of FCEVs.
