Abstract: Danwei System was a gradually constructed tool by the nation to achieve communism and modernization in the period of planned economy and under special historical conditions. The representation of its fundamental characteristic is“urban unit”. Both the nature and feature are unfolded in spatiality, temporality and sociality. Danwei research System can help understand the history of planned economy to sublate Danwei factors through evaluation. Also, Danwei System research forms an important and special perspective not only to understand the mechanism of the urban transition in China but also to analyze those problems in the same period. As far as future planning is concerned, Danwei System research can promote further protection and development of those old Danwei, as well as help the application of the positive factors to new urban increments. Danwei System research in the perspective of geography can be carried out in three related aspects, the first space, the second space and the third space. The first space research consists of spatial structure, function and deformation of the physical space; the second space research describes and explains the spatial representations of political organization, professional function and society and culture; the third space research will be done in different perspectives and methods to deconstruct spatial conflicts in Danwei space and construct harmonious space. The research in the perspective of geography includes three scales, social scale, spatial scale and temporal scale. The existing research has made some important achievements, but much more work needs to be done in the aspects of span, theoretical depth and interdisciplinary studies.
