基于专利分析的我国大数据产业技术竞争态势研究

A Study on the Competition Situation of Big Data Technology in China on the Basis of Patent Analysis

通过Soopat和Derwent Innovations Index平台,利用专利分析方法从我国本土和全球布局两个视角对我国大数据产业技术竞争态势进行全面扫描。主要从年度申请量、生命周期、国家或地区分布、申请人、专利分类号(IPC)、专利地图、专利引证等角度对我国大数据产业的技术发展趋势、技术竞争区域、技术竞争主体和技术竞争领域等4个方面进行实证分析。结果表明,我国大数据产业技术竞争环境基本形成"内热外冷"的整体格局:大数据技术处于快速增长阶段、技术竞争区域主要以国内为主、高校与企业共同引领技术竞争主体、技术竞争领域保持与全球同步。

By using patent analysis methods, competition situation of big data technology in our country was scanned in Soopat and Der- went Innovations Index patent platform at home and abroad. An empirical investigation about the technological development tendency, competitive regions, competitive subjects, and competitive fields of big data technology in China was then performed from the perspectives of annual trend, patent life-cycle, country or region, applicant, patent IPC, patent map and patent citation, etc. Research shows that compe- tition environment of big data technology in our country was formed. Big data technology is in the stage of rapid growth ,patents are mainly distributed in domestic market, universities and enterprises are jointly the main applicants, and key technology keeps pace with the global ones.
