Historic district regeneration often faces a disjunction between spatial reproduction and value creation. This study proposes a Dual-Helix Synergy Model, integrating a “spatial reproduction chain” and a “value creation chain” through four “base-pair” space typologies: Symbiotic Engine, Community Lounge, Professional Workshop, and Dormant Node. Using analytic network process (ANP) with supplementary social network and spatiotemporal analyses, we examine the micro-regeneration of Yongqing Fang, Guangzhou. We identify an evolutionary pathway (“Dormant Node → Professional Workshop → Community Lounge → Symbiotic Engine”) and introduce the synergistic conversion rate (SCR) to measure coupling efficiency. The four SCR phases (0.90, 1.10, 0.43) reveal a non-monotonic pattern, with economic revenue rising 100%, cultural capital 92%, and social trust 78% from 2016 to 2024. The findings suggest that, within this specific case context, sustainable regeneration is associated with integrating cultural, economic, and social values through networked spatial nodes. As these findings are derived from a single case, generalizability to other institutional contexts requires further empirical testing. Theoretically, the model advances regeneration research from binary opposition to systems thinking. Practically, it offers a diagnostic and intervention toolkit for historic district governance.
