This academic work, inheriting and developing the basic principles of Marxism, analyzes the world's historical structure by using materialist dialectics and forecasts the direction of the socialist movement and the ways to realize communism. It not only makes up for the horizontal dynamic part of Marxist theory but also points out a logical path for the development of human society. Furthermore, it predicts the proposal and practice of China's "the Belt and Road Initiative" from various aspects and provides the theoretical basis and rationale for building a community with a shared future for mankind.
