本文分析了从国民党统治到共产党政权的过渡时期内(1949—1952)中国共产党实行的统一战线政策,以及上海资产阶级对此做出的反映和结果。在此阶段内,中国共产党对工商界采取了逐步加强监督管理的策略。而上海资产阶级从现实利益出发,以爱国主义和现代化等崇高的理念为名义,同意与共产党结盟。一年半后,共产党以对资产阶级的控制取代了联盟,上海资产阶级的地位从共产党的合作者变成共产党的助手。 This article analyzes the policy of the united front carried out by the communist party during the transitional period from the reign of the Kuomintang to the communist regime (1949-1952), and the reaction and result made by the Shanghai bourgeoisie. During this period, the CPC has adopted a strategy of stepping up its supervision over the business community. The bourgeoisie in Shanghai, proceeding from its real interests, took the lofty idea of ​​patriotism and modernization as its name and agreed to alliance with the Communist Party. A year and a half later, the Communist Party replaced the Alliance with control over the bourgeoisie and the status of Shanghai bourgeoisie from an associate of the Communist Party to an aide of the Communist Party.
