摘要:
［目的］专利作为技术创新能力的重要标尺，对轨道交通装备的创新发展具有重要意义。当前我国轨道交通装备领域专利价值的系统性评估尚显不足，需对其创新趋势与价值进行深入分析。［方法］通过大为innojoy全球专利数据库检索获得所需的专利数据信息，利用统计方法对我国轨道交通装备领域的专利进行技术创新总体分析及技术构成与演化分析；采用4个专利指标根据主成分分析法对主要申请人和主要技术领域的专利价值进行评估。［结果及结论］我国轨道交通装备领域的技术创新呈增长趋势，但合作情况有待提升，技术大类中计算方法方向伴随数字化浪潮蓬勃兴起。高价值专利分布在主要技术领域，该领域高校的整体专利价值基本高于企业。我国轨道交通装备领域的技术创新发展趋势稳步向好，未来可聚焦高价值技术创新方向，进一步深化校企产学研合作。
Abstracts:
［Objective］ As an important yardstick for measuring technological innovation capabilities, patent is of great significance to the innovative development of rail transit equipment. Currently, the systematic evaluation of patent value in the field of rail transit equipment in China is still insufficient, and it is necessary to make an in-depth analysis of its innovation trends and value. ［Method］ The required patent data information is retrieved from the Dawell Innojoy Global Patent Database. Statistical methods are utilized to conduct an analysis of technological innovation in general and an analysis of the technological composition and evolution of patents in the field of rail transit equipment in China. Four patent indicators are adopted to evaluate the patent value of major applicants and technological fields based on the principal component analysis method. ［Result & Conclusion］ The technological innovation in China′s rail transit equipment presents a growing trend, but the collaboration needs to be improved. The direction of computational methods among the major technology categories is booming along with the wave of digitalization. High-value patents are distributed in the major technological fields, where universities hold patents of basically higher value as a whole than those enterprises do. The development trend of technological innovation in the field of rail transit equipment in China is steadily positive. In the future, the direction of high-value technological innovation can be the focus, and the cooperation among universities, enterprises and research institutions in production, education and research can be further deepened.
