北平的和平解放以及中共北平市委按照毛泽东“原封原样接收”思想对北平的先接后管，都充分反映了中共对古都的重视和对北平文化背景的认识。然而，中共对解放初北平现状进一步了解，是在接收的过程中逐步完善的。北平解放初，由于和平接管，旧时代遗留下的社会问题无法在短期内予以解决，社会状况极为混乱，敌情严重，治安相比围城期间更为复杂。在对北平的历史及现状认识的基础上，中共在国民党旧职人员的处理、社会混乱现象的消除、特务的肃清及反动党团分子的登记、乞丐妓女的收容教育等方面进行了一系列革故鼎新的工作。中共为巩固北平新生的政权而进行的初步实践，保障了政权的平稳过渡，赢得了民众对新政权的信任与支持。北平解放前后，中共中央正考虑党的工作重心的转移和进城后的相关问题，由此，对北平的接管也适时地体现了中共城市工作的初步理念。在城市中，中共依靠谁、建立什么样的城市，是摆在中国共产党人面前必须要解决的问题。中共在巩固北平新生政权的过程中，逐步形成了控制城市社会的初步理念，即依靠工人阶级，团结教育工人群众，坚持走群众路线和建立新民主主义的新城市。这种城市控制理念必然成为中共在随后解放城市运行的模本，并且将日臻完善。

The peaceful liberation and taking over of Beiping by the Communist Party of China were done followed Mao Tse-tung’s instruction “take everything as it was”, which reflects the importance attached by the party to the traditional city and its culture. However, because of the mild way, it is during the stage of taking over the city that the party knew better of the situation of the city which was then plagued by such problems as espionage, prostitution and social chaos left by the former regime and could not be solved in a short period.Based on her knowledge of the Beiping’s present and past, the Party executed a variety of policies to strengthen the new power, and the policies included relocating of the public servants of the Kuo Ming Tang, the rooting out of spies and registration of the counter-revolutionary societies, and the housing and educating of the prostitutes and beggars. Thus the new government was successfully established and won the local people’s trust and support.In the process of liberating Beiping, the Communist Party was trying to change the emphasis of her work and adapt to new environment of the city. And the taking over of Beiping reflects well the party’s concern of depending on whom and building what kind of city. The answer they found was to depend on the working class, follow the mass line and build cities on the ideal of New Democracy, and this concept was taken as the principle in city management in later times.
