Leninism is Marxism in the age of imperialism and proletarian revolution.As a development and innovation of Marxism during the practice of socialist revolution in the age of imperialism,it created a theory of imperialism,proposed the victory of socialism in one country,adhered to and developed the Marxist theory of party building and the theory of dictatorship of proletariat,advocated and implemented the“New Economic Policy”and the theory of“circuitous transition”to socialism. Leninism is an indispensable and important theoretical foundatrion for the sinicization of Marxism.In the great cause of the sinicization of Marxism,the Communist Party of China should not only unswervingly take Marxism-Leninism as the theoretical basis of its guiding ideology,but also adopt a scientific attitude of seeking truth from facts and keeping pace with the times．
