以社会主义初级阶段理论为立论基础 ,并经过以邓小平为核心的第二代中央领导集体和以江泽民为核心的第三代中央领导集体的艰辛探索 ,中国共产党创立并形成了“阶段性”发展理论。这一理论历经了从“三步走”发展战略到“台阶式”发展思想 ,再到“具体发展过程的阶段性”思想的两次大飞跃 ,凝结了两代领导人的集体智慧 ,是我国改革开放和现代化建设实践经验的最新总结 ,丰富和发展了社会主义初级阶段的理论。进入新世纪 ,学习掌握党的“阶段性”发展理论 ,必将增强我们分阶段有步骤扎扎实实推进我国社会主义现代化建设的自觉性和坚定性 ,并最终实现中华民族的伟大复兴 Based on the theory of the initial stage of socialism and through the arduous exploration of the second generation of the central collective leadership with Deng Xiaoping as the core and the third generation of the central collective leadership with Jiang Zemin as the core, the CPC has created and formed a “phased” development theory.
