在民国新闻史研究中，蒋介石对新闻宣传的布置和管控始终是较为薄弱的环节，据《蒋介石日记》（手稿本）及相关蒋档记载，蒋介石在1928至1949年间，大量参与了新闻宣传活动，《日记》中也涉及到大量新闻史人物和他对新闻宣传的观点。1943年8月 25日，蒋介石在其日记中写道：“宣传重于军事”，这与其军事家、政治家的形象大相径庭。本文综合梳理了此间蒋介石所面临的整个国民党文宣系统的运行和失误，认为他之所以发出“宣传重于军事”的感慨，在于其借用人际关系建构的文宣系统，运行到 1943年，在诸多国内外新增压力下，变得漏洞百出，国民党宣传战的失败也从此开始。

The Chiang Kai-shek Dairy is an unexplored treasure for the research of Journalism history. From 1928 to 1949, the dairy recorded a lot of events, people and opinions about the Journalism. In August 1943, Chiang Kai-shek wrote in his diary that “propaganda is more important than military affairs”, which is quite different from the image of his militarists and politicians. This paper combs the operation and failure of the whole KMT propaganda system. Under many new pressures in China and overseas, the KMT propaganda was full of loopholes. The defeat of the war began from then on.
