Research Review on Technology Convergence Based on Patent Data 后印本

Abstract: [Purpose/significance] Technology convergence research based on patent data is the main way and hot direction of technology convergence research. In order to support following research work of technology convergence, this paper reviews the current research of technology convergence based on patent data. [Method/process] According to the research content, the existing research can be divided into six categories:the research on the measurement and prediction method of technology convergence; the measurement and trend prediction of specific field, multi fields and whole field technology convergence; the research on the measurement index of technology convergence; the research on the characteristic factors influencing the technology convergence; the technology opportunity discovery based on the perspective of technology convergence and the research on the relationship between technology convergence and innovation. The research results were also commented. [Result/conclusion] Research on technology convergence based on patent data has achieved certain results, but there are still some problems, such as unreasonable measurement basis, lack of validation of prediction methods and low attention of the whole field research. These problems can be solved by introducing semantic relationship to optimize technology convergence network, using GNN technology to improve technology convergence prediction method and improving technology convergence measurement and prediction in the whole field.
