The people-centered development thought is a significant part of Xi Jinping Thought on Socialism with Chinese Characteristics for the New Era and a concentrated expression of Marxism in the 21st century.The perspective of historical materialism provides the main theoretical support for the people-centered development thought based on the dimensions of reality,society,individuals,and human dimensions.They clarify the inherent requirements of this thought:focusing on the"real existence"of people,grasping the"social existence"of people,respecting the"individual existence"of people,and dealing with human"natural existence"appropriately.This undoubtedly inherits and develops the mass perspective of Marxism and the traditional people-oriented thought in China,consolidating the ruling position of the CPC in the new era,addressing prominent issues in the process of Chinese-stye modernization.
