Abstract: From the level of political culture, institutional system and behavior patterns, this paper makes an in-depth study of the CCP mass line during the Soviet period. From their attitudes, emotions and values, Chinese Communists identified that the masses of the people is the lifeline of its development and growth. A series of systems were also formulated during the Soviet period, which provided a platform and security for the political participation of the general public. The behavior patterns of the Chinese Communists were closely related to the actual effects of the mass line. As a political party, Chinese Communist Party takes the “mass line” as the main line and has basically achieved a positive interaction and balance between the “political ecology” and “Human Ecology”, which can also provide some lessons for the party activities in reality.

Key words: mass line; Soviet area; political ecology
