摘要
探索重大发明创造的技术多元化特征,有助于把握重大发明创造的规律、推动突破性创新活动的进行。选取《德温特创新索引》数据库中符合设定条件的专利数据,采用技术共类分析方法,分别以高被引、中被引和零被引专利代表不同层次的发明创造技术,通过四项指标探测重大发明创造是否具有更加明显的技术多元化特征。分析结果表明,其中三项指标验证了这个研究假设。就单项专利技术的R&D研发活动而言,技术多元化更有可能产生重大发明创造。
Analyzing the technology diversification characteristics of significant inventions will be great significance in grasping the law of significant inwentions, and improving innovative activities. Choosing the given patent dataset in Derwent Innovations Index, employing technology co-classification analysis, and considering highly-cited patents, middle-cited patents and zero-cited patents as different level inventions, by using four indicators, we ex- plore the issue whether significant inventions have the characteristics of technology diversification. The results show that the former three indicators verifies the research hypothesis. In terms of individual patent R＆D activity, maybe diversification is helpful to significant inventions.
