摘　　要：[目的/意义]构建基于LDA的企业竞争对手识别模型,在海量同领域企业中精准识别竞争对手,剖析其技术发展领域,为企业制定竞争策略提供情报支撑。[方法/过程]首先,根据技术领域与目标企业下载专利数据;其次,将目标企业与相同技术领域企业专利数据合并,对专利摘要进行主题建模并借助LDAvis可视化工具与相对接近度计算识别潜在竞争对手;最后,借助LDA模型、困惑度与主题相似度计算潜在竞争对手技术多样化指数(TD)与技术专业化指数(TS),通过竞争力气泡图识别竞争对手类型,从而完成竞争对手识别模型的构建。[结果/结论]构建的企业竞争对手识别模型可以较好地识别出目标企业的竞争对手,并建议目标企业应积极对标竞争对手的技术领域,制定相应发展战略,从而促进企业在激烈的市场竞争中脱颖而出。[Purpose/significance]Build a Corporate Competitor Identification Model based on LDA,accurately identify competitors among a large number of enterprises in the same fields,analyze their technology development fields,and provide intelligence support for enterprises to formulate competitive strategies.[Method/process]Firstly,the patent data is downloaded according to the technology fields and the target enterprises.Secondly,the patent data of the target enterprises and the enterprises in the same technology fields are combined,and the patent abstracts are subject-modeled and the potential competitors are identified with the help of LDAvis visualization tool and relative proximity calculation.Finally,the technology diversification index(TD)and technology specialization index(TS)of potential competitors are calculated with the help of LDA model,perplexity and subject similarity,and the competitor types are mapped by the competitiveness bubble,so as to complete the construction of the competitor identification model.[Result/conclusion]This model can better identify the competitors of the target enterprises,and suggest that the target enterprises should actively compare the technical fields of the competitors and formulate corresponding development strategies,so as to promote them to stand out in the fierce market competition.
