有的学者提出，前苏共丧失执政地位的根本原因是由于苏联社会长期以来存在着三大矛盾和苏共党内三种势力代表对其采取错误对策的结果。第一大矛盾是苏共“左”的路线和过度集权的党政领导体制同社会主义社会要求尽快发展生产力，发展民主与自由的矛盾；第二大矛盾是党政军官僚? Some scholars have suggested that the fundamental reason why the former Soviet Union loses its ruling position is the result of the three major contradictions in the Soviet society and the mistaken responses of the three representatives of the Soviet Communist Party. The first major contradiction is the line of the “Left” of the CPSU and the conflict between the party and government over-centralized leadership system and the demands of the socialist society for the rapid development of the productive forces and the development of democracy and freedom. The second major contradiction is that of the party, government and army bureaucrats.
