城市发展进程中，历史文化街区的更新正面临着挑战。文章以南京钓鱼台历史街区为例，探索盈利导向下的更新路径。通过田野调查、GIS分析和数据整合，发现三大核心矛盾：空间再生产失衡、主体利益割裂和经济动能阻滞。提出“分阶段盈利导向”策略，即外生动力阶段依靠政府完善基础设施；内生动力阶段推动“共享院”模式试点；共生动力阶段实现业态升级和差异化路线设计。整合成本效益分析框架与空间经济学理论，提出多维协同治理路径，平衡保护与开发矛盾，为居住型历史街区的可持续更新提供参考。

In the process of urban development, the regeneration of historic and cultural districts faces significant challenges. This study takes Nanjing's Diaoyutai District as a case to explore profit-oriented regeneration pathways. Through field investigations, GIS analysis, and data integration, three core contradictions were identified: imbalanced spatial reproduction, fragmented stakeholder interests, and blocked economic momentum. A "phased profit-oriented strategy" is proposed: Exogenous-driven phase: Government-led infrastructure enhancement; Endogenous-driven phase: Pilot "shared courtyard" community models; Symbiotic-driven phase: Business format upgrades and differentiated cultural-tourism route planning. By integrating a cost-benefit analysis framework with spatial economics theories, the study proposes a multidimensional collaborative governance pathway to balance preservation and development conflicts, offering insights for the sustainable regeneration of residential historic districts.
