基于专利分析和 SWOT 分析的我国增程式电动汽车开发战略研究

摘要

从专利申请区域分布、专利申请年度分布、技术领域年度分布、专利申请人、核心专利等5个方面对增程式电动汽车开展专利分析，基于专利分析结果及相关市场和政策环境对我国增程式电动汽车的开发开展 SWOT分析，指出我国在增程式电动汽车开发方面已具有一定的竞争实力，在成本上具有优势，具有市场利好和政策利好，但在关键技术研发方面还较为落后且面临较强的专利壁垒。据此，给出我国增程式电动汽车产业发展对策建议。%In this paper,the patent analysis of extended range electric vehicle (EREV)was carried out,with patent appli-cation regional distribution,patent application year distribution,main technology fields year distribution,main patent appli-cants and core patents highlighted.Based on the patent analysis result,as well as relative market and policy environment, a further SWOT analysis towards the development of EREV in China was performed.The analysis results indicated that Chi-na had a certain competitiveness and cost advantage in the development of EREV.Moreover,the market and policy for ER-EV were positive.But China lagged behind in key technologies research and development,and was facing strong patent bar-riers.Accordingly,the countermeasures and suggestions for the development of EREV in China were presented.
