The profound conceptual vitality of "localization" in the humanities and social sciences has endowed archival cultural and creative research and practice with constructive epistemic significance. Taking two ACC exhibitions organized by the Society of Chinese Archives as case studies, this paper analyzes the localization features of archival cultural and creative products—spanning production, memory, conceptualization, and emotion—and reveals their generative logic from material carriers to cultural identity. The study identifies critical challenges in current practices, including imbalance in cultural attributes, superficial interpretation of symbols, and limited communication efficacy. A four-dimensional optimization framework is proposed: cultural integration, experiential enhancement, demand-oriented engagement, and meaning reconstruction. These pathways aim to promote the transition of "localization" from spontaneity to consciousness, thereby providing theoretical and practical foundations for constructing archival cultural services with Chinese characteristics.
