本文主要以战时上海媒体文化的转变为中心,重点探讨日本帝国主义对中国媒体文化转变的影响。文中根据战前国民政府与上海民营报业的关系及其对国民政府战争动员的影响,集中阐述了太平洋战争爆发后,日本侵略者和汪伪政府直接控制上海报业,钳制沦陷区人民群众的思想言论。因此,战时上海媒体文化转变后所做的宣传,既不为中国人民所信任,也无法配合汪伪政府的战争动员,更无力支持日本帝国主义者的侵略战争政策。 This paper mainly focuses on the change of media culture in wartime Shanghai and focuses on the influence of Japanese imperialism on the change of media culture in China. According to the relationship between the pre-war National Government and the privately owned newspapers in Shanghai and its impact on the mobilization of the KMT government, this paper focuses on the direct control by the Japanese invaders and Wang’s puppet government on the press in Shanghai and the suppression of the people in the occupied areas following the outbreak of the Pacific War Thought and speech. Therefore, the propaganda made after the wartime media culture in Shanghai was transformed was neither trusted by the Chinese people nor could it be coordinated with the wartime mobilization by the Wang pseudo government, but even less capable of supporting the Japanese imperialists’ policy of aggressive war.
