基于专利技术共现网络的共性技术识别——以家电行业为例

Generic Technology Identification Based on Technology Co-occurrence Network of Patents:Case Study of Household Appliance Industry

[目的/意义]识别产业共性技术对实现科技资源高效分配与共享,以及影响国家产业发展路径的选择具有重要的理论意义和现实意义。[方法/过程]基于专利技术共现网络,结合社会网络分析中的K-核分析、中心性分析等相关理论和方法,探索产业共性技术的识别方法,并以家电产业为例进行实证研究,得出以海尔、美的、格力三家家电领跑企业所代表的家电产业的共性技术以及共性技术的演化趋势。[结果/结论]家电产业的共性技术集中在“空气调节、空气增湿、通风”“制冷设备、加热和制冷联合系统、热泵系统”“冷柜、冷藏室、冰箱”这三类中,“气温、外气、湿度等与空气特性相关的控制输入”可能是家电产业新兴共性技术的研究方向。

[Purpose/significance]Generic technology identification has great theoretical and practical significance to realize efficient allocation and sharing of scientific and technological resources and to choose the development path of national industry.[Method/process]Based on the technology co-occurrence network of patents combined with the theories and methods of K-Core analysis and centrality analysis in social network analysis the paper explores the identification method of industrial generic technology and takes the household appliance industry as example obtains the generic technology and evolution trend of home appliance industry represented by Haier Midea and Gree.[Result/conclusion]The results show that the generic technology in home appliance industry focuses on the“Air conditioning air humidification ventilation”“Refrigeration equipment combined heating and cooling system heat pump system”and“Refrigerator freezer refrigerator”.“Control inputs related to air characteristics such as air temperature external air humidity etc”may be the research direction of emerging generic technology in household appliance industry.
