列宁通过分析帝国主义时代的特征及其基本矛盾,发现了资本主义经济政治发展不平衡的规律,进而得出了新的结论:社会主义有可能首先在少数甚至单独一个国家内获得胜利,修正了马克思、恩格斯关于社会主义革命首先在几个发达的资本主义国家同时取得胜利的公式。社会主义在一国取得胜利,并且在一个贫穷落后、生产力不很发达的俄国取得了胜利。如何建设社会主义呢?这与马克思、恩格斯原来的设想有了很大的差异。 By analyzing the characteristics and basic contradictions of the era of imperialism, Lenin discovers the law of unbalanced economic and political development of capitalism and concludes with the new conclusion that socialism may first win victory in a few or even a single country and amend Marx and Engels first formulated the formula on which victory the socialist revolution won simultaneously in several developed capitalist countries. Socialism won in one country and won in Russia, poor and backward, with less developed productive forces. How to build socialism? This is quite different from the original ideas of Marx and Engels.
