解放战争是由中国共产党领导的，为推翻国民党反动统治，解放全中国而进行的一场关乎中国前途命运的重要战争。解放战争初期，国民党军队的装备优良、物资条件充足，无论在官兵数量还是军队质量上，与共产党相比都是占据了绝对优势。但是随着历史的发展，中国共产党领导的人民解放军逐步扭转战局，最终赢得了解放战争的胜利，并且用时远远小于时间预期。战争能够取得胜利有诸多因素，除了国民党的腐败统治与人民解放军的战略战术得当之外，党宣传工作的成功是绝不可忽视的一环。

总体来说，解放战争时期中国共产党宣传工作的内容和载体都有鲜明的特点。这一时期党的宣传工作主要有三种载体，分别是印刷类、文艺类和电台类。解放战争时期宣传工作内容也根据战争进程在不同阶段呈现不同特点，本研究主要分为三个阶段：为争取和平民主进行的宣传、战略防御阶段和反攻阶段的宣传、战略决战阶段的宣传。为争取和平民主的宣传内容主要以战后局势分析、揭发国民党暴行和瓦解敌军为主；随着全面内战爆发，战略防御阶段和反攻阶段的宣传内容包括战事消息播报、土地改革运动和国统区学生运动等方面；在战略决战阶段的宣传，主要任务是对革命进行到底的宣传，关于城市保护和纪律的宣传与旧中国宣传机构的接管也是极为重要的工作。在中国共产党制定的一系列政策方针下，解放战争时期宣传工作开展得如火如荼、卓有成效，在瓦解敌军、动员群众参军、鼓舞士气、坚定理想信念等方面都作出了极大贡献。

本研究从中国共产党在解放战争时期开展的宣传工作实践中主要总结了四个方面的经验：一是党的正面引领能够坚定宣传工作的方向；二是宣传内容与时俱进可以增强宣传影响；三是加强宣传者与宣传对象的双向互动；四是宣传策略灵活多变有助于提高宣传效率。这些历史经验在当代中国依然有重要的价值。

The liberation war is an important war led by the Communist Party of China to overthrow the reactionary rule of the Kuomintang and liberate the whole China. In the early days of the liberation war, the Kuomintang army had excellent equipment and sufficient material conditions. Compared with the Communist Party, it had an absolute advantage in both the number of officers and soldiers and the quality of the army. However, with the development of history, the People 's Liberation Army led by the Communist Party of China gradually reversed the war situation, and finally won the victory of the war of liberation, and took far less than time expected. There are many factors for the victory of the war. In addition to the corrupt rule of the Kuomintang and the proper strategy and tactics of the People 's Liberation Army, the success of the party 's propaganda work is an indispensable part.

Generally speaking, the content and carrier of the propaganda work of the Communist Party of China during the liberation war have distinct characteristics. During this period, there were three main carriers of the party 's propaganda work, namely, printing, literature and art, and radio. The content of propaganda work during the liberation war also showed different characteristics according to the different stages of the war process. This study is mainly divided into three stages : propaganda for peace and democracy, propaganda in the strategic defense stage and the counter-offensive stage, and propaganda in the strategic decisive stage. The propaganda content of striving for peace and democracy is mainly based on the analysis of the post-war situation, exposing the Kuomintang atrocities and disintegrating the enemy. With the outbreak of the comprehensive civil war, the propaganda contents of the strategic defense stage and the counterattack stage include war news broadcast, land reform movement and student movement in the Kuomintang-controlled areas ; in the stage of strategic decisive battle, the main task is to publicize the revolution in the end. The publicity of urban protection and discipline and the takeover of the old Chinese propaganda institutions are also extremely important work. Under a series of policies and guidelines formulated by the Communist Party of China, the propaganda work during the War of Liberation was carried out in full swing and fruitful. It made great contributions to disintegrating the enemy, mobilizing the masses to join the army, inspiring morale, and strengthening ideals and beliefs.

This study mainly summarizes four aspects of experience from the propaganda work practice of the Communist Party of China during the war of liberation : First, the party 's positive leadership can strengthen the revolutionary direction ; second, the propaganda content with the times can enhance the propaganda influence ; third, strengthen the two-way interaction between propagandists and propaganda objects ; fourth, flexible publicity strategies can help improve publicity efficiency. These historical experiences still have a lot of inspiration in contemporary China, and also play an important role in realizing Chinese-style modernization.
