党的先进性是具体的历史的,人民的利益也是具体的历史的。党只有实现了人民的根本利益,才能体现先进性;党只有具备了先进性,才能实现人民的根本利益。在中国革命、建设和改革的全过程中,党以最广大人民群众的根本利益为目标,不断实现人民的利益,始终保持先进性,从而受到人民的拥护和支持,获得合法性认同。 The advanced nature of the party is specific to history, and the interests of the people are also specific to history. Only by realizing the fundamental interests of the people can the party demonstrate its advanced nature. Only when the party possesses the advanced nature can the fundamental interests of the people be realized. In the entire process of China’s revolution, construction and reform, the party, with the fundamental interests of the overwhelming majority of the people as the goal, has continuously realized the interests of the people and always maintained its advanced nature, gaining the support and support of the people for its legitimacy.
