Abstract: The activity of "Jiangning in Memory" conducted by Jiangning Road Sub-district Office, Jing'an District, Shanghai is a response to the rapid change of an urban block by retaining local collective memory. By applying multiple qualitative research methods such as non-participatory observation, household interview, depth interview of key figures and text analysis, this paper explores whether a cultural map could be an effective carrier of local collective memory, and analyzes the mechanism of subject participation and its influence on the construction of local collective memory through the compilation process of a cultural map. It is found that the cultural map in the activity of "Jiangning in Memory" can be an effective carrier for the construction of local collective memory, within which the residents' participation is an important condition. There exists unequal power relationship among different subjects in the compilation of a cultural map and its elements selection, which shows that the local collective memory carried by a cultural map is also a result of social construction. Finally, this paper discusses the significance of the activity of "Jiangning in Memory" for urban space making and the construction of local collective memory.
