基于专利情报分析的中国数控机床产业研究

Analysis of Chinese CNC Machine Industry Based on Patent Intelligence

以德温特创新索引专利平台(Derwent Innovation Index,DII)收录的1963-2009年数控机床产业专利为研究对象,借助专利情报分析方法,对我国数控机床产业专利信息进行分析。通过对比日本、美国和德国的专利信息情况,分别从专利整体产出情况、重点研发技术领域和研发机构专利布局等角度揭示出我国数控产业的发展变化,为全面掌握数控产业技术创新动向与创新发展提供可靠的参考依据。

Based on patents information collected by Derwent Innovation Index database from 1963-2009, this paper investigates and ana- lyres the innovation status and development trends of CNC machine technology in China. Through a comparative analysis on the patent da- ta of China, Japan, US and Germany, the quantitative analysis in this paper reveals the overall patent situation, the key RSd） fields and the R＆D institutes patent distribution involving the major companies as patent applicants or holders in the industry in China. The paper hopes to provide an objective statistical reference for future academic researches and innovation development in the CNC machine industry.
