中共二大在党的创建史上具有重要的里程碑意义,制定了彻底的反帝反封建的民主革命纲领。为何在建党仅仅一年后的中共二大就能够提出反帝反封建的革命纲领?许多学者认为有两点原因:其一是得到了列宁和共产国际国际的帮助和指导,其二是中国共产党对革命探索的经验总结。然而笔者认为,上述两方面的原因还不足以说明中共二大为何能提出民主革命纲领。回应当时中国政治界不同的主张是其中重要的一个因素。 The Second Congress of the CPC has an important milestone in the party’s history and has formulated a complete program of democratic revolution against imperialism and feudalism. Why was it that the Second Plenary Session of the CPC was able to come up with a revolutionary program against imperialism and feudalism only a year after its founding? Many scholars think for two reasons: one is the help and guidance of Lenin and the Comintern International, and the other is that the Chinese Communist Party Experiences in the exploration of revolution. However, the author believes that the above two reasons are not enough to explain why the Second Congress of the Communist Party of China proposed the program of democratic revolution. Responding to the different opinions of the Chinese political circles at the time was one of the most important factors.
