群众性是中国共产党党报的重要原则，群众在党报报道中曾有过不同的定位。从中共早期党报实践到《解放日报》改版前，群众是党报教育、组织和鼓动的对象；改版后，在抗日战争时期，党报成为群众的报道者、反映者和喉舌；抗战胜利后，尤其自土地改革宣传开始，群众逐渐成为党报工作者“学习的对象”。“群众性”内涵重心的不断变化，背后的原因比较复杂，既有党报工作者对群众认知的改变，也有不同历史时期宣传政策调整、甚至党的大政方针调整的原因。

Mass character is an important principle of Chinese party newspaper, and there had been a different position on masses in the party newspaper. From the early Chinese party newspaper to "Liberation Daily" before the revision, the masses in the party newspaper are the object of education, organization and agitation; After the revision, the party newspaper become a reporter, reflect and mouthpiece on masses during the Anti-Japanese War; After the victory of the war, especially since the beginning of the land reform propaganda, masses gradually become "learning objects" among party newspaper Workers. The focus of "mass" connotation had been changed constantly, and the reasons behind are the more complex, including both the party workers' cognitive change to the masses and the adjustment of propaganda policy during different periods of history, and even the adjustment of party's fundamental policy.
