摘　　要：为了对技术发展路径中关键技术的选择更为准确,文章综合专利直接被引和间接被引的信息设计了专利引证强度指标,并将该指标和专利引用网络思想相结合提出了关键技术发展路径算法。以电动汽车为例进行方法验证,并对其中最大的技术子图进行了聚类分析、4个发展阶段的解读和技术创新点的判断。结果显示该方法不仅有助于简化技术发展的复杂结构,勾勒出由关键技术组成的发展路径,同时对技术创新点预测也提供了一个新思路。In order to select a more accurate key technology for technology development path,this paper designs patent citation strength indicator based on the information of patent direct citation and indirect citation,and combines the indicator and patent citation network to propose algorithm for key technology development path. Taking electric vehicle as an example to verify the method,the paper carries on cluster analysis for the main technical subgraph,as well as the interpretation and judgment for its 4 development phases and technical innovations. The result shows that this method is not only helpful for simplifying the complex structure of technology development and building the development path with key technology,but also helpful for proposing a new idea for the prediction of technology innovation.
