Identification and Prediction of Key Technologies Based on Logistic Model and SPC Algorithm:Taking Satellite Internet as an Example
Identifying key technologies helps to gain a first mover advantage in formulating technological and market strategic layouts,which is of great significance to China's economic development and national security.This article proposes a key technology identification method that integrates lifecycle and main path analysis,which is an important supplement to existing research theories and methods.Firstly,re-trieve patent data in relevant fields and divide them into different domains;Secondly,the Logistic model and SPC algorithm are comprehensively used to construct a technological trajectory and identify key tech-nologies;Then,use the Explicit Technological Advantage Index to compare the technological competition trends of major countries;Finally,drawing a technology roadmap based on key technologies and techno-logical competition trends,identifying technology hotspots and frontier predictions.Taking satellite Inter-net as an example,the application process of this method is described.The research results indicate that this method can accurately identify key technologies in this field,reveal the global technological competi-tion situation,and effectively achieve technology hotspot identification and future technology prediction;The identified key technologies of satellite Internet can provide reference for national development policy formulation and relevant industrial layout.
