摘要:
采用专利计量分析方法，从专利申请数量趋势、主要申请机构、研发方向、被引次数及专利价值等多角度探讨了我国地铁技术的发展现状。分析结果表明：近年来我国地铁技术相关专利数量整体呈现上升态势，现阶段仍处于快速发展时期；研发热点集中在B61、G01、G06等IPC（国际专利分类）分类号；高被引专利的总数不多，价值度为7的专利数量最多，专利质量仍须提升。建议继续提升专利创造能力和竞争力，助力我国地铁技术持续高速发展。
Abstracts:
By adopting patentometrics analysis method, from angles including patent application number trend, main application institutes, research directions, citation times and patent value, the current status of metro technology in China is discussed. Analysis results show that the number of patents related to domestic metro technology presents an overall upward trend, and the current stage is still in a period of rapid development; the research hotspot focuses on IPC B61, G01, G06 and so on; the number of highly cited patents is not much in total, and the number of patents with value of 7 is the largest. The quality of patents still needs improvement. It is suggested to improve the patent creativity and competitiveness to help sustaining the high-speed development of China′s metro technology.
