Abstract: Military-civilian integration is the process that integrates national defense construction into economic construction system and optimizes resource allocation.Clearing the overall research context is of great significance to subsequent theoretical research and practical exploration.Using information visualization software CiteSpace, this paper studies 513 academic articles in CNKI database from 2004 to 2018, aiming to clarify the time, periodicals, authors and institutions of military-civilian integration research.With the methods of keywords co-occurrence, hot words burst term and key phrases clustering, the knowledge structure relationship and evolutionary law of this area are revealed.The conclusion comes as: military-civilian integration has become a hot research topic since 2011.During 2015-2018, researchers mainly focus on collaborative innovation, economic efficiency, and technology transformation.Universities and research institutes related to national defense are the backbone of military-civilian integration.The provinces of traditional military industry and political center are the main gathering place of this research.Key phrases centralize on "military-civilian integration", "deep development", "aerospace", "collaborative innovation", "economic efficiency" and "national defense science and technology".Most studies are mainly on empirical judgment or macro-countermeasures.Of those burst terms, the "military and civilian combination" is of the highest intensity, and the "industrial cluster" lasts shorter than any.The research trend basically follows the national policy orientation.
