The concept of building a community of common health for mankind, put forward by President Xi Jinping, represents a major theoretical innovation in adapting Marxism to the Chinese context and the needs of the times. It provides a profound explication of the paradigm transformation and the practical path of global health governance. In terms of the subject dimension, it builds a cooperative pattern of joint contribution and shared benefits. In the health dimension, it establishes a coordinated mechanism for joint prevention and control. In the governance dimension, it establishes a practical consensus on mutualistic symbiosis. These dimensions demonstrate the theoretical characteristics, including scientific, people-centered, practical, innovative and systematic. A systematic analysis of a community of common health for mankind across the three dimensions of scientific connotation, theoretical characteristics, and contemporary value holds great theoretical value and practical significance for improving the global governance system and advancing the development of a new form of human civilization.
