Research Hotspots and Dynamic Analysis of Knowledge Spillover in Modern Service Industry Based on CITESPACE Big Data Analysis

The rapid and sustainable development of economy and society requires us to abandon the previous development mode and carry out the optimization and adjustment of industrial structure. In this paper, we use Citespace software and knowledge graph visualization technology to analyze the core journals in the database in terms of keyword analysis and literature co-citation analysis based on the database information of WOS, with “modern service industry” and “knowledge spillover” as the themes. Through the visual analysis of the knowledge map, we comprehensively study and discuss the current status of research on “modern service industry” and “modern service industry” related to knowledge spillover, as well as the research hotspots and development trends in various periods, so as to prepare for the next step of “knowledge spillover in modern service industry”. It will pave the way for the next research on “knowledge spillover in modern service industry”.
