中文摘要：

专利竞争情报技术可以为产业技术路线图的绘制发挥重要作用。将多重关系专利网络分析技术引入产业技术路线图的制定中，并选取电动汽车锂电池这一新兴领域进行实证研究。构建了由5个层面的网络共同组成的多重关系专利网络，进行了多重专利关系网络演化分析、关键成员识别与子群分析，最后对分析结果在产业技术路线图绘制中的应用进行了解读。分析结果表明：多重关系整合方法能够促进整个专利数据分析的全面性与准确性，对多重关系整合的专利网络分析能够更好地描述网络的整体演化情况，也能更好地捕捉到个体在组织中的重要性，且能比单一层次内的分析获得更多信息。

英文摘要：

The patent competition intelligence can play an important role in industry technology roadmapping. In this paper, the multi-re-lation integrated patent network analysis method is introduced in the rendering of industry technology roadmap. A multi-relation integrated patent network composed of 5 layers networks is constructed, and then the patent network＇s evolution, the key entity identification and subgroup division are processed. The analysis results show that the multi-relation integrated method can improve the comprehensiveness and accuracy;the overall evolution and the node＇s importance of the organization can be better described and more information can be ob-tained compared to the single layer patent network.
