Review on Research Methods of Technological Topic Evolution

Abstract

[Purpose/significance] The analysis of technological topic evolution is of great significance for understanding the technological development process and forecasting technology trends in the future. Exploring the roadmap of research methods of technological topic evolution analysis is helpful to understand its research status and lay the foundation for further research. [Method/process] This paper divided the existing research methods of technological topic evolution analysis into three major categories: qualitative methods, quantitative methods and hybrid methods combining qualitative and quantitative analysis, and then describes representative methods for each category. [Results/conclusion] Based on the systematic analysis of current research methods of technological topic evolution, the author discusses the shortage of existing research methods and prospects for future research.
