Can Collective Memory be Cognized after Heritage Revitalisation? Cases of Shanghai and Hong Kong

Abstract. The Heritage revitalisation is a necessary process of urban renewal and development. Collective memory is the core value of heritage revitalisation carrying the history and cultural information, as well as reflecting the local daily lives. Thus, it is essential to preserve the collective memory during the revitalisation. However, various reasons can lead to its preserved consequence, and various people have different cognition for it. To analyse the influential factors of the memory cognition after heritage revitalisation, the study proposed a comprehensive framework comprising subjective analysis and objective exploration, traditional methods and novel techniques. Influential factors include tangible parts and intangible parts. Tangible parts include global integration, local integration and intelligence of spatial characteristics. Intangible parts are dominantly inclusive of activities held at the sites. Through analysis, the study found that the preservation of memory information and activities can influence human behaviors, and these behaviors can generate different cognitions for the memory of heritage revitalisation. The finding explores the interaction of space, people and memory, enhances the heritage revitalisation in a vivid way, and lays the solid foundation for future urban (re)development.
