| 摘 要： | 以德温特数据库的专利信息为数据源,采用专利计量、社会网络分析等方法,以云计算领域的专利为研究对象,从宏观、中观、微观三重视角,对云计算领域的专利进行分析。从宏观角度来看,云计算专利正处于迅猛发展阶段,且美国的基本专利数量最多。从中观角度来看,在专利权人合作粒度上,中外具有较大差异性,同时,产生合作关系的专利权人在主营业务领域上具有相似性。从微观层面来看,中国公司在云计算领域的合作率和合作强度低于国际知名公司,这在一定程度上阻碍了知识的流动和传播以及国家技术生产率的提高。

| Abstract: | Choosing patents in cloud-computing field in Derwent Innovation Index as the objective, this paper analyzes these patents from micro, middle and macro perspectives with patent bibliometrics and SNA methods. In macro view, cloud-computing patents are in the period of rapidly developing, and America owns more patents than the other countries. In middle view, there is a great difference between China and foreign countries in cooperative particle size, and the cooperative institution is similar in primary business. In micro view, the cooperation rate and cooperation intensity of Chinese companies are weaker than international famous international companies, which hinders flow and diffusion of knowledge and the increase of technology productivity. |
