租界是近代中国半殖民地化的象征 ,但又树立了近代西方城市的模板 ,促进了中国城市的近代化 ;租界是西方列强掠夺中国人民财富的基地 ,但又是中国近代经济发展的一种促进因素 ;租界既是殖民侵略的桥头堡 ,又是先进的资本主义文明在落后的封建中国的窗口。租界充当了历史的“不自觉的工具”。 The concession symbolized the semi-colonialization of modern China, but also set a template for the modern western cities and promoted the modernization of Chinese cities. The concession was the base for Western powers to plunder the wealth of the Chinese people, but it was also a promotion of the economic development in modern China Factors; the concession is not only a bridgehead for colonial aggression, but also the window of advanced capitalist civilization in the backward feudal China. The concession serves as an “unconscious instrument” of history.
