阶级性是政党的本质属性。但是,民主党派具有不同于其它政党的特殊性和复杂性,在讨论中国各民主党派问题时一般不采用“阶级基础”的提法,而是代之以“社会基础”。民主党派的社会基础随着社会的发展而不断发展。 Class nature is the essential attribute of a political party. However, the democratic parties have a peculiarity and complexity different from those of other political parties. When discussing the various democratic parties in China, they usually do not adopt the reference of “class basis” instead of “social basis.” The social foundation of democratic parties continues to evolve with the development of society.
