The impact of regional architecture on residents’ identities varies, involving complex emotional aspects. We conducted an in-depth study of the deep connection between regional architecture and identity in China’s Huizhou and Minnan regions, highlighting its key role in stimulating authentic pride. Initially, we carried out a survey among 433 residents from both regions using questionnaires to obtain quantitative data, revealing the mediating role of authentic pride. Subsequently, we conducted in-depth interviews with 20 residents from 4 villages of the 2 regions, and the coding results explained the multidimensional reasons behind the quantitative analysis outcomes. This research not only deepened the understanding of how regional architecture impacts identity recognition but also highlighted the urgency of preserving regional culture under the pressures of globalization and modernization. Moreover, this study provided strong reasons for the preservation of architectural heritage, emphasizing its importance as a cornerstone of identity and a means to enhance community cohesion.
