Abstract: The ideological history of the Communist Party of China (CPC) is highly isomorphic with the history of social progress in China and the history of the rejuvenation of the Chinese nationThe centennial ideological history of the CPC is also the history of continuously promoting the sinicization of Marxism, and facilitating theoretical innovation and creationFour central clues run through this historical process, namely the CPC's ideological theme, ideological system, ideological building and ideological communicationThe ideological history is a dynamic reflection of the real historyStanding up, growing rich, and becoming strong have been the ideological themes of the CPC at different historical stages, showing the CPC's ideological and theoretical exploration into and response to fundamental issues of the timesThe CPC has established an ideological system characterized by original contribution and powerful vitality, which derives from but goes beyond practice, and realizes the creative unity of “explaining the world” and “changing the world”The CPC attaches much importance to ideological building and theoretically strengthening the PartyIt takes ideological building as a fundamental task, and arms the Party members and guides the practice with its innovative theoriesFrom the introduction of Marxism into China to the international spread of Marxism of contemporary China and Marxism in the 21st century, the CPC's ideological communication has achieved historical development and increasingly manifested the world historical significance of the Chinese way of modernization.

摘要： 中国共产党的思想史与中国社会的进步史、中华民族的复兴史是高度同构的。一部中国共产党的百年思想史，就是一部不断推进马克思主义中国化的历史，就是一部不断推进理论创新、进行理论创造的历史。这一历史进程贯穿着中国共产党的思想主题、思想体系、思想建设与思想传播这四条核心线索。思想的历史是现实历史的能动反映，站起来、富起来与强起来，构成了不同历史阶段中国共产党的思想主题，反映出党的思想理论对于时代根本问题的求索与回应。中国共产党在实践中建构起具有原创性贡献与强大生命力的思想体系，这一思想体系源于实践又高于实践，实现“解释世界”与“改变世界”的创造性统一。中国共产党注重从思想上建党、从理论上强党，把思想建设作为党的基础性建设，用党的创新理论武装全党、指导实践。从马克思主义传入中国，到当代中国马克思主义、21世纪马克思主义走向世界，党的思想传播实现了历史性发展，愈发彰显出中国式现代化道路的世界历史意义。
