Abstract: Since the founding of the Communist Party of China (CPC), the understanding and expression of Party spirit have shown different patterns in different periods. During the Yanan period, the concept of Party spirit of the CPC was initially formed, and the establishment of the Party being a proletariat party was emphasized as the core connotation of Party spirit. During the period of socialist revolution and construction, the focus of the CPCs discourse on Party spirit changed, and the concept of “keeping the people firmly in mind” and the spirit of seeking truth from facts became the central content of Chinese Communists interpretation of Party spirit. In the new era of reform and opening up and socialist modernization, the CPC has put forward a series of new ideas, viewpoints and conclusions in terms of the construction of organizational discipline and the shaping of ideological concepts, thus further extending its concept of Party spirit. Since the 18th National Congress of the CPC, the concept of Party spirit of the CPC has achieved innovative development. The historical changes in the CPCs conception of Party spirit are of great significance to the correct interpretation and the clarification of ambiguous understanding of the connotation of Party spirit, and the promotion of the construction of the discourse system of the discipline of Chinese Communist Party history and Party building.

摘要： 中国共产党成立以来，有关党性的理解和表述在不同时期呈现出不同的样态。延安时期，中国共产党的党性观念初步形成，党的阶级性作为党性的核心内涵被重点阐述。社会主义革命和建设时期，中国共产党关于党性的言说重心发生改变，群众观念和实事求是精神成为共产党人诠释党性的中心内容。改革开放和社会主义现代化建设新时期，中国共产党在组织纪律建设和思想观念塑造方面提出了一系列新的思想、观点和论断，从而使其党性观念进一步延展。党的十八大以来，中国共产党的党性观念实现创造性发展。梳理、考察中国共产党党性观念的历史变迁，对于人们正确理解党性内涵、澄清模糊认识，以及推进中共党史党建学科话语体系建设都具有重要意义。
