【目的】提出不依靠专利引文数据、利用专利文本数据评价企业技术实力的方法。【方法】该方法综合采用专利授权数量指标、专利增长率指标、技术中心性指标和专利最小价值指标来评估技术实力。这4类指标分别从技术规模、技术增长性、技术重要性和技术价值性等不同侧面反映一个企业的技术能力。【结果】通过CII和TII指标对比实验,验证引文分析给公开早的专利较高评价的问题;通过TS指标和TSQGIV对比实验,验证提出的技术实力评价方法的有效性。【局限】数据处理中没有对机构名称进行规范化处理,实验结果可能存在误差。【结论】相比于其他评价技术实力的方法,本研究可以在没有引文数据的情况下对企业的技术实力进行评价。 【Objective】 To propose a method to evaluate the technical strength of enterprises without using patent citation data and using patent text data. [Method] This method comprehensively adopts the quantity index of patent authorization, the index of patent growth rate, the technology center index and the patent minimum value index to evaluate the technical strength. These four kinds of indicators respectively reflect the technological capabilities of an enterprise from different aspects such as technical scale, technological growth, technical importance and technical value. 【Result】 The results of CII and TII index comparison experiments were used to verify the citation analysis for early public patent higher evaluation. Through the TS and TSQGIV comparative experiments, the validity of the proposed technical strength evaluation method was verified. [Limitations] There is no standardization of the agency name in data processing. The experimental results may have errors. 【Conclusion】 Compared with other methods to evaluate the technical strength, this study can evaluate the technical strength of enterprises in the absence of citation data.
