以世界主要钢铁企业为研究对象,以德温特世界专利索引为数据来源,探讨研发投入与专利影响力之间的关系。首先,对专利权人在专利中的排序进行探讨,提出专利权人的权重测定方法,在此基础上,从总被引数、篇均被引数、H指数及其衍生指数等角度对企业研发投入与专利影响力进行了实证研究。结果表明,在钢铁领域,企业的研发投入与专利影响力有正相关的关系,且专利权人加权指数对于影响力的评价具有一定的调整作用。
Taking the world's major iron and steel enterprises as the research object and Derwent World Patent Index as the data source, the relationship between R & D investment and patent influence is discussed. First of all, this paper discusses the patentee's ranking in the patent and puts forward the method of determining the weight of the patentee. On the basis of this, it gives some suggestions on the R & D of the enterprise from the aspects of the total quoted quota, the average quoted quotient, the H index and its derivative index And the impact of patents conducted an empirical study. The results show that there is a positive correlation between R & D investment and patent influence in the iron and steel industry, and the patentee weighted index has a certain adjustment effect on the evaluation of influence.
