Identifying and Evaluating Cultural Genes in the Historic Centre of Macao: A Multi-Stakeholder Perspective

Under the dual pressures of urbanization and tourism development, the Historic Centre of Macao, as a World Cultural Heritage site, faces challenges including the inadequate transmission of cultural elements and the excessive commercialisation of tourism development. To systematically identify and safeguard its cultural characteristics, this study introduces the theory of cultural genes, constructing a dual-strand identification model encompassing both tangible and intangible cultural genes. This model integrates architectural function, structure, and ornamentation, alongside indigenous religions, arts, and folklore, thereby achieving a comprehensive extraction of cultural elements. Building upon this foundation, the study employed the AHP-fuzzy comprehensive evaluation method to quantitatively assess the degree of identification with various cultural elements, integrating perspectives from three distinct groups: tourists, residents, and third-party experts. The findings revealed significant disparities in cultural identification across these groups. For instance, residents demonstrated the highest level of identification with beliefs and folk customs, whilst tourists favoured more tangible aspects such as decorative elements and cuisine, exhibiting generally weaker identification with architectural structures. The findings demonstrate that this study, through the establishment of a systematic framework for identifying cultural genes and a multi-stakeholder evaluation system, has accurately discerned the characteristics of various cultural genes and the public’s level of identification with them. This provides a scientific basis for evidence-based, differentiated, and precise governance of the Historic Centre of Macao, offering significant reference value for the conservation and revitalisation of similar cultural heritage sites.
