Abstract: The great call of the “three musts” put forward by the 20th National Congress of the Communist Party of China is the political declaration of the Communist Party of China on its new journey to comprehensively build a modern socialist country. Comparing the “change” and “no change” of the core logic of “three musts” and “two musts” has important theoretical and practical significance for the new journey of the second centenary goal. In the new development stage, the “change” of the core logic of the “three musts” is mainly the “change” of external direction, practical field and practical needs, that is, the change of struggle mentality, struggle environment and struggle goal. The “no change” of the core logic of the “three musts” is mainly the “invariance” of the fundamental premise, political stance, and ideal original intention, that is, the sobriety and political determination of the big party, the position and guiding ideology of the people, the original intention of the century and the mission of the times. At the same time, the relationship between “change” and “no change” is dialectical unity between phenomenon and essence, subjective and objective, reality and ideal.

Key words: “three musts”; core logic; dialectical relation

摘要： 党的二十大报告提出“三个务必”伟大号召，是中国共产党在全面建设社会主义现代化国家新征程上的政治宣言。比较“三个务必”与“两个务必”核心逻辑的“变”与“不变”，对走好第二个百年奋斗目标新征程具有重要理论和实践意义。在新发展阶段，“三个务必”核心逻辑的“变”主要是外在指向、实践场域、现实需要之“变”，即奋斗心态、奋斗环境、奋斗目标的变化；“三个务必”核心逻辑的“不变”主要是根本前提、政治立场、理想初衷之“不变”，即大党清醒与政治定力、人民立场与指导思想、百年初心与时代使命的不变。同时，“变”与“不变”之间分别表现为现象与本质、主观与客观、现实与理想的辩证统一关系。
