Abstract

In order to explore the application status of Big Data in the field of smart city, this paper uses the literature visualization tool CiteSpace to systematically sort out and quantitatively analyze the related literature from CNKI from 2013 to 2023. By constructing a Knowledge Graph based on core information such as publication time, research institutions, core authors, and keywords, this paper aims to reveal the research hotspots and development trends in this field. The research finds that since 2013, the application research of Big Data in the field of smart city has shown an overall growth trend, and the number of related research papers has risen rapidly, while forming a dense small-scale cooperation network. The keyword co-occurrence and cluster analysis show that big data application plays an important role in the E-government, elderly service, natural resources, urban planning, rail transit, electricity, medical care, and other fields in smart city. At present, urban governance, emergency decision-making and information security have become the research focuses in the field of smart city.
