基于专利引用的计量分析是测度跨国知识流动的有效方法,通过分析知识在各个国家(地区)之间的流动情况,为发现和认识不同国家(地区)产业创新主体间的知识流动与交互作用提供了独特的分析视角。以计算机与通信产业领域为例,开展基于专利跨国引用网络的产业创新国际化知识流动测度。研究发现,产业创新主体在进行专利发明的过程中,更多关注国外同行的专利技术,并通过专利引用将其吸入到自己的专利产出中;新兴国家(地区)尽管进入了中心组,但是对于网络的影响有限;中国台湾和韩国的赶超轨迹,值得其他国家(地区)借鉴。
The quantitative analysis based on patent citation is an effective method for measuring transnational knowledge flow. The understanding of knowledge flow among countries (regions) provides a special perspective to enhance the realization of the interaction between different national (regional) industrial innovation subjects. This paper takes the industrial field of computers and communications as an example to measure the knowledge flow of industrial innovation internationalization based on the transnational patent citation network. The paper finds that the subjects of industrial innovation pay more attention to the patented technology of foreign counterparts and adapt such technology into their own patent output through patent citation. And although emerging countries (re-gions) enter the core group, their influence on the network is limited. The advancing track of Taiwan and South Korea is worthy of study by other periphery countries and regions.
