思想是行动的先导，理论是实践的指南。回溯抗日战争时期，中国共产党带领中国人民取得全民抗战的胜利，其中最主要的原因之一就是重视党的思想建设。为了适应抗战的需要，统一全党思想，通过规范党内思想、深入群众进行宣传和动员、促进革命理论通俗化、开展作风整顿等途径，凝聚思想、汇聚民心，确保党在抗战时期的领导力、战斗力与威信力。深刻总结党在抗日战争时期的经验启示，有助于在新的时代征程上激发磅礴奋进的力量、筑牢广泛的社会共识。

Thought is the precursor of action, and theory serves as a guide for practice. Looking back at the period of the War of Resistance Against Japanese Aggression, one of the primary reasons for the victory achieved by the Chinese Communist Party and the Chinese people as a whole was the emphasis placed on the Party’s ideological construction. To meet the needs of the war effort, unify the Party’s ideology, promote popularization of revolutionary theory, conduct ideological rectification, and mobilize the masses through various means, such as standardizing Party ideology, engaging in extensive propaganda and mobilization efforts, and fostering a sense of unity and shared purpose among the people, all of which ensured the Party’s leadership, combat effectiveness, and prestige during the war. A thorough analysis of the Party’s experiences and lessons learned during the War of Resistance can help unleash powerful momentum and build broad social consensus in the new era.
