Abstract: In the rapid development of the contemporary China,what is the position of the city's tradition and history? This paper studies the city changes in the framework of the tradition-modernity,taking Beijing as an example,through the comparison between Beijing,Paris,and Tokyo. It focuses on the changes of the traditional urban communities in the modern history of China,the relationship between Chinese traditional urban communities and the modernization process and their “future possibilities”in the current process of city modernization in China. Compared with some particular foreign cities,the traditional city appearance in China replaced by the modern urban space,is gradually fading away. Unless the traditional space in cities would adapt itself to the demand of the commercial development and modernization renewing,or it will be replaced by the new type of the urban space.
