Abstract: Spenglers theory of the life cycle of cultures has made the issue of how to transcend or resolve the constraints of such a cycle a major intellectual challenge.  Relevant research, both in China and abroad, offers us ample insights for reference. The Marxist conception of culture, in essence, provides a transcendental interpretation that offers fundamental theoretical guidance for deciphering the life cycle of cultures. Centering on the concept of a “new cultural organism”, Xi Jinping Thought on Culture advances both theoretical and practical innovations, thereby providing a guiding framework and opening new pathways for fundamentally addressing the issue of the life cycle of cultures. It not only directs China in promoting its cultural prosperity, building up its cultural strength, and ensuring the enduring development of Chinese civilization, but also inaugurates a new paradigm in the history of human civilization for achieving the sustainable development of civilization through boosting our awareness of Chinese culture.

Key words: Xi Jinping Thought on Culture, new cultural organism, life cycle of cultures, Spengler

摘要： 斯宾格勒提出的文化生命周期理论使得如何破解文化生命周期成为一个重大课题。国内外相关研究为我们提供了丰富借鉴。马克思主义文化观实质上对之进行了超越性阐释，为破解文化生命周期提供了原理性启示。习近平文化思想以“新的文化生命体”为内核进行理论与实践创新，为从根本上破解文化生命周期提供了指南，开辟了道路，既指引中国推动文化繁荣、建设文化强国进而确保中华文明永续发展，也在人类文明史上开创了通过文化自觉实现文明永续发展的新范式。
