马克思晚年在研究俄国社会未来发展前景时,提出了跨越资本主义“卡夫丁夹谷”的设想。这一设想,突破了科学社会主义理论初定模式,第一次探索了东方落后国家如何实现社会主义的问题,它是历史唯物主义和科学社会主义理论的一次新拓展,为东方落后国家走社会主义道路指出了方向和科学的方法论原则。中国共产党几代领导人通过对社会主义理论与实践的探索,走出了建设有中国特色社会主义的新路子,以新的理论和实践丰富、发展了马克思列主义。 In his later years, in studying the future development of Russian society, Marx proposed the idea of ​​crossing the capitalist “Cafudine Valley.” This idea broke through the initial mode of scientific socialism theory and first explored how the underdeveloped countries in the East can realize socialism. It is a new expansion of the historical materialism and scientific socialism theory, The path of direction points out the methodological principles of direction and science. Through the exploration of the theory and practice of socialism, several generations of leaders of the Chinese Communist Party stepped out of a new path of building socialism with Chinese characteristics and enriched and developed Marxism-Leninism with new theories and practices.
