Evolution Path and Development Trend of Domestic Marine City Research --- A Visual Analysis Based on CiteSpace

Abstract

This paper uses the information visualization software CiteSpace, through the main research methods of spatiotemporal knowledge atlas and content knowledge atlas analysis, to search the CNKI with "marine city" as the key word or title. The publication time is selected from 2012 to 2022. A total of 146 effective documents are retrieved for analysis, revealing the current research hotspots and development frontier of marine cities in China. The analysis results show that the development of the research field of marine cities presents three stages: the first stage is from 2012 to 2016, and the publication volume of the documents related to marine cities is relatively flat; the second stage is from 2017 to 2020, showing a trend of steady growth year by year; the third stage is from 2021 to 2022, when the number of marine cities shows a "blowout" surge. The authors and institutions of the papers present scattered distribution, and the parts are slightly tight. The research focuses on three aspects: Marine center city, Marine industry and Marine power, and the research context is easily affected by the policy effect, showing a dynamic development trend. At present, academic research on marine cities is relatively scarce. Therefore, this paper gives a further summary and reflection, with a view to providing a reference for further research, exploration and promotion of marine undertakings in China's marine cities.
