专利视角下中国新能源汽车动力电池机构技术竞争力研究

[目的/意义]旨在利用专利文献分析中国动力电池机构的技术竞争力,为企业提前进行专利布局和预警提供情报支持和参考。[方法/过程]基于incoPat数据库的专利数据,构建包括技术规模、技术质量和技术价值三个一级指标和九个二级指标的技术竞争力评价指标体系,利用层次分析法和无量纲处理方法,深度分析新能源汽车动力电池机构的技术竞争力。[结果/结论]我国动力电池行业技术竞争力排名前百的机构中,企业数量占据绝对优势,且很多企业技术竞争力值相对较高,高校数量排在其次,科研院所数量则相对较少。从地域分布来看,我国新能源汽车动力电池技术竞争力强的机构主要聚集在广东、北京和安徽三个省市。从动态分析来看,比亚迪股份有限公司、北京新能源汽车股份有限公司和武汉格罗夫氢能汽车有限公司极具发展潜力和创新活力。企业可结合机构技术竞争力、地域分布和动态变化选取合作伙伴,也可对同区域技术竞争力较强的企业提前采取专利预警措施。

Forecasting promising technology using analysis of patent information:Focused on next generation mobile communications

In order to forecast promising technologies in the field of next generation mobile communication, various patent indicators were analyzed such as citation per patent, patent family information, patent share, increase rate, and patent activity. These indicators were quantified into several indexes and then integrated into an evaluation score to provide promising technologies. As a result of the suggested patent analysis, four technologies out of twenty two in details classification were selected, which showed outstanding technology competitiveness, high patent share and increasing rates as well as high recent-patent-ratios and triad-patent-family-ratios. Each of the selected technologies scored more than 10 points in total, and the following four technologies were suggested as promising ones in the field of next generation mobile communication: 1) 3GPP based mobile communication, 2) beyond 4G mobile communication, 3) IEEE 802.16 based mobile communication, which are in medium classification of broadband mobile communication system, and 4) testing/certification system of mobile communication, which is in medium classification of mobile communication testing/certification system.
