摘　　要：【目的/意义】在现今激烈的市场竞争中,技术竞争力对企业整体竞争力有重要影响。通过更细粒度地刻画技术竞争格局,企业可根据发展需求制定相应的竞争策略。【方法/过程】将专利文献的国际专利分类号(International Patent Classification,IPC)、德温特手工代码(Manual Code,MC)、术语(Term)依次组合为不同的IPC-MC-Term三元组,将所有三元组构建为一个高维向量空间,每个三元组视为其中的一个维度。通过机构专利权人在IPCMC-Term三元组向量空间中进行投射后的位置计算机构专利权人之间的相似度,以分析技术竞争格局,并在水处理领域进行应用分析。【结果/结论】研究结果表明:该方法有利于从更微观的技术方向上识别机构专利权人的技术竞争关系,更具化地描述技术竞争态势。[Purpose/significance ]In the current fierce market competition,the technological competitiveness has an important impact on the overall competitiveness of enterprises.Through a more fine-grained description of the technical competition pattern,enterprises can formulate corresponding competitive strategies according to the development needs.[Method/ process]The International Patent Classification (IPC),Manual Code (MC)and terms of the patent documents are sequentially combined into different IPC-MC-Term triad,and all triads are constructed as a high-dimensional vector space,with each triad is considered as one of the dimensions.The similarity between the patentees is calculated by the position of the patentees after projection in the vector space of IPC-MC-Term triad to analyze the competition pattern and applies in the field of water treatment.[Result/conclusion]The result shows that the method is beneficial to identify the technical competition of patentees from a more micro technical direction and to describe the technology competition situation more concretely.
