研究技术演进路径对于把握技术脉络、预测技术发展趋势和学习先进技术具有重要意义。本文设计动态支持度阈值进行专利引文过滤,通过专利的关联关系建立专利技术网络,然后采用局域、全局和关键路线搜索算法简化技术路径,从而得到技术演进路径。相比传统主路径分析方法,该方法在选取关键专利节点和描述专利关系上更加合理准确。最后通过对有机发光二极管领域的实证,从结构内容、专利分布、专利强度统计检验几个方面证实了该方法的有效性。

Discovering the technological path is of great significance in tracing the history of technology development, predicting technology development trends, and learning advanced technologies. We design a dynamic support threshold to filter unnecessary patents and then form a patented technology network based on the relationship between patent citations. Finally, we obtain a simplified technological path map with the path searching algorithm. Compared to the main path analysis method, our proposed method is more reasonable and accurate in selecting key patent nodes and analyzing patent relations. W...
