1. The Soviet Union was founded:1At the end of 922, the Union of Soviet Socialist Republics was referred to as "the Soviet Union". The first four republics: Russian Federation, Transcaucasian Federation, Ukraine and Belarus. Later, it was expanded to 15 participating republics.

The great achievement of Soviet socialist construction in the 1920s and 1930s: When the capitalist world was in economic crisis, the Soviet economy developed rapidly. In a short time, more than 9,000 new enterprises were put into production, and heavy industries such as machinery manufacturing were established one after another. 1937 The total industrial output value of the Soviet Union ranks first in Europe and second in the world. The Soviet Union has developed from an economically backward agricultural country to a world-class industrial power, realizing socialist industrialization.

Third, the Stalin model:

1, the symbol of its formation:1The formulation of the new Soviet Constitution in 936 marked the formation of a highly centralized economic and political system in the Soviet Union. It also marks the establishment of the socialist system in the Soviet Union.

2. The content of Stalin model: industrialization and agricultural collectivization.

3. Evaluate Stalin's model:

Positive role: it played a positive role in a certain historical stage, making the Soviet Union rank among the industrialized countries and laying a material foundation for the victory of the world anti-fascist war.

Negative effects: ① There is no distinction between party and government in politics, the Soviet Union exists in name only, democracy and legal system are lacking, and personality cult and paternalism prevail; (2) Economically, market regulation and the law of value are excluded, and administrative means are used to intervene in the economy, resulting in a serious imbalance in the development of economic sectors and a long-term stagnation of agriculture. In a word, the Stalin model hinders the full play of the superiority of the socialist system.
