Research on Technological Convergence Analysis Framework Based on Patent Co-classification——Taking the Convergence of Elderly Gerontechnology and Information Technology as an Example

Purpose/Significance]Technogical convergence is an important means of technological innovation.Analysis of technogical convergence is of great significance for enterprises to gain insight into technology opportunities and plan R&D activities.Method/Process]Based on patent co-classification,the analysis framework of technogical convergence was constructed from the overall and local perspectives.At the overall level,the network indicators were analyzed for the network formed by technogical convergence.At the local level,node and link analysis were carried out for the selected key technologies,among which node analysis included correlation degree,uniformity and gravitation analysis,and link analysis included cohesion subgroup,tightness and difference analysis.Finally,an empirical study was conducted on the convergence of elderly gerontechnology and information technology.Result/Conclusion]The proposed analysis framework was helpful to grasp the overall trend of technogical convergence and R&D hotspots,and could effectively identify the core technology nodes and links.
