现今东欧社会民主主义运动中的特点之一是左派阵营里的力量很难拧成一股绳，内部纷争激烈，派系矛盾突出，严重地影响了左派的行动能力和战斗力，无法共同主宰国家的政治生活。１９９６年以前社会民主派的矛盾主要表现在新、旧社会党的关系上，此后既有实用主义政治操作上的分合；又有不适应议会民主制规则带有旧体制烙印的权力之争；也有思想纲领方面的差异。随着东欧社民党的逐渐成熟，今后左派阵营内无聊纠纷的成份将会减少，逐渐会形成分野明朗的左、右翼，而集中于执政纲领、大政方针方面的区别，向类似于西欧社会党的方向发展。 One of the characteristics of the social-democratic movement in Eastern Europe today is that the forces in the camp of the left are hardly twisted into one strand. The fierce internal disputes and the prominent conflicts among the factions disproportionately affect the ability and fighting capability of the left and can not jointly dominate the political life of the country . The contradictions of the social democrats prior to 1996 were mainly manifested in the relations between the new and old Socialist parties. Since then, they have not only the division of pragmatism in their political operations, but also their dispute over the power of parliamentary democracy with old system imprints. Differences in the ideological program. With the gradual maturity of the Social Democratic Party in Eastern Europe, the composition of the bordering disputes in the leftist camp will decrease in the future and gradually form a left-wing and a right-wing society with a clear distinction. The difference concentrates on the ruling agenda and major policies and principles and will develop in a direction similar to that of the West European Socialist Party .
