Abstract: After the outbreak of the War of Resistance against Japanese Aggression, the Communist Party of China, in accordance with the historical environment and main tasks at that time, timely shifted the focus of ideological construction from class struggle to the fight for national liberation. Bearing in mind the new strategy of the Chinese united front against Japanese aggression, the Communist Party of China insisted on adapting the basic tenets of Marxism to Chinas specific realities, and resolutely fought against all hostile ideas, thus building a common ideological foundation for the Party to lead the people to win the complete victory in the War of Resistance against Japanese Aggression and the Chinese revolution, defending the guiding position of Marxism in the field of ideology, realizing the first historic leap in adapting Marxism to the Chinese context, iedeveloping Mao Zedong Thought, and promoting ideological construction into a new stage. Although the Partys ideological construction in different historical stages is different in form and content, the basic experience of the Party in leading ideological construction during the Yanan period provides enlightenment for ideological construction in the new era, which is of great significance for building a socialist ideology with strong cohesion and leadership.

Key words: Yan'an period, Marxism, the Communist Party of China, ideological construction 

摘要： 抗日战争爆发后，中国共产党根据当时的历史环境和主要任务，适时把意识形态建设的中心从阶级斗争转向民族斗争。围绕抗日民族统一战线的新策略，中国共产党坚持把马克思主义基本原理同中国具体实际相结合，对一切敌对思想进行坚决斗争，从而筑牢了党领导人民夺取抗日战争和中国革命最后胜利的共同思想基础，捍卫了马克思主义在意识形态领域的指导地位，实现了马克思主义中国化的第一次历史性飞跃——毛泽东思想，推动意识形态建设进入新阶段。尽管在不同历史阶段党的意识形态建设在形式和内容上有所不同，但延安时期党领导意识形态建设的基本经验，可以为新时代意识形态建设提供一些方法借鉴，对于建设具有强大凝聚力和引领力的社会主义意识形态具有重要意义。
