基于专利的技术融合测度方法——以信息技术与电动汽车技术的融合为例

Method of Measuring Technology Convergence Based on Patent——Taking the Convergence of Information Technology and Electric Vehicle Technology as an Example

现代科技的发展使得信息与其它技术组成的技术群落及各技术群落之间相互联系、渗透不断加强,出现了各种技术的交叉融合。如果能及早发现这些技术领域间目前的融合状态及其融合趋势,将会对我国在相关技术方面的优先研发制定发展战略产生重大意义。为解决这个问题提出了一个定量测量技术融合的框架,该框架以专利数据为依据,通过对技术融合的宏观和微观相结合来确定融合的现状,其中微观分析中主要针对技术融合所形成网络的节点以及链路进行测度。最后以德温特数据库中纯电动汽车技术和信息技术的融合为实例对其进行验证。针对实例研究,结果表明G06F(电数字数据处理)、B60L(电动车辆的电力装备或动力装置)、H02J(电能存储系统)等技术与其它技术比较容易发生融合且融合能力较强。G06FB60W,G05F-H02M等技术对的融合在技术融合中起到了较重要的作用,且其融合强度质量均较高。

The development of modern science and technology makes technical communities compose by information technology and other technologies, and various technical communities continue to strengthen the contact and penetration, so appears a variety of technologies＇ cross-convergence. If these technological field＇s current convergence state and the trend of convergence were detected earlier, it will have a major significance on our country＇s priority development and strategies making. To solve this problem, this article proposed a framework based on patent data to measure the technology convergence, and through combining macro and micro study of technology convergence, it could determine the state of convergence. And at the same time the. data of electric vehide technology and information technology＇s convergence from Derwent databases was used as an example to verify.it. The results showed that G06F （ electric digital data processing ） , B60L （ power equipment or power plant of electric vehicle ） , H02J （ electric energy storage system ） and other technologies were more prone to converge with other technologies .and its convergence ability was strong. The convergence of G06F-B60W and G05F-H02M played a more important role in the technology convergence, and their convergence strength and quality was higher too.
