Abstract Frontier technologies refer to the guiding and advanced core technologies in high-tech fields.The accurate identification and prediction of frontier technologies is crucial to the effective allocation of technical resources.From the perspective of patent topic similarity, this study develops a frontier technology identification method covering outlier technologies, and introduces the technology evolution law (nine screen method)of the TRIZ theory to predict the future frontier technologies, including determining the current system, identifying technological evolution points and extending prediction.By collecting the data of graphene patents from 2001 to 2021, this study empirically identifies and predicts the frontier technologies in the graphene field.The findings show that the frontier technology identification method developed in this study can make up for the lack of completeness of traditional identification methods, and accurately identify the outliers and non-hot frontier technologies.The extending prediction results of frontier technologies are of great reference value for the technology layout of future industries.

Key words： Frontier technology Patent topic similarity network Technology evolution law Technology identification Technology prediction
