基于专利分析的通信制造业上市公司技术竞争力评价研究

Research on Technology Competitiveness Evaluation of Communications Manufacturing Listed Corporation in China Based on Patent Analysis

通信行业是我国制造业发展的缩影。选取通信制造业一家具有代表性的上市公司Z为研究对象,通过共现分析和社会网络分析等信息可视化方法对Z公司专利数据集进行可视化,采用历年专利数量分布、高被引专利分析、德温特手工代码和技术主题4个维度从技术层面进行分析,并归纳从技术研发投入、技术研发规模、技术研发质量3个角度构建企业技术竞争力评价指标体系;建立灰靶理论评价模型展开实证分析,通过德温特手工代码共现分析来识别出Z公司及通信领域内的技术热点,可视化Z公司在全球范围通信领域内的竞争态势,从专利信息分析的视角把握通信制造业上市公司竞争力现状。将实证分析结果与专利计量的结果进行对比分析,结合十九大报告关键词,为Z公司战略决策提出建议,以期为通信领域企业发展提供科学参考。

Com m unication industry is the epitome of the development of China's manufacturing industry. Z company, a communication manufacturing firm is selected as the representative of listed company research object in this paper, the patent data set of Z company is visualized by information visualization methods such as co-occurrence analysis and social network analysis, carries out the analysis based on four dimensions of patent quantity distribution, high cited patent analysis, D erw ent manual code and technical theme, and summarizes from three angles of technology R & D investment, technology R & D scale, technology R & D quality to build enterprise technology competitiveness evaluation index system. The evaluation model of grey target theory is established to carry out empirical analysis, and the technical hotspots in Z company and communication field are identified by Derwent manual code co-occurrence analysis, and the competitive situation of Z company in the field of global communication is visible, grasps the competitiveness of listed companies in communications manufacturing industry from the perspective of patent information analysis. Finally, the paper compares the results of empirical analysis with the results of patent measurement, combined w ith key words reported in the 19th National Congress of the Communist Party of China, and puts forward some suggestions for the strategic decision of Z company, in order to provide scientific reference for the development of enterprises in the field of communication.
