摘要：社交媒介与城市空间的“虚实互动”已成为一些地区城市更新的重要特征，但当前研究对虚实关系和媒介作用的认知尚不全面。本研究通过梳理整合“从实到虚”“从虚到实”“虚实混合”三种路径，建立了虚实互动的城市更新分析框架，并以朝天宫街道为例解析机制演进：（1）虚拟符号建构向实体具身访问延伸，启动了分散自主更新；实体集聚格局与虚拟热点链接相互促进，引发了街巷串联更新；“媒介凝视”固化多元共治的社会纽带，推进了街区协商更新。（2）社交媒介实现了载体与主体间的转换与兼容，一方面承载公众愿景表达、商家路线营销、游客身份展演和政府方案宣传，传播空间印象、热点格局、引流规律；另一方面通过算法控制强化虚拟链接，施加“媒介凝视”塑造虚实地方感。（3）社交媒介激发了市场活力，推动了公众参与，吸引了政策关切，使城市更新从分散走向整合、从自下而上走向上下联动，应因势利导有序推进。
Abstract：The “virtual-physical interaction” between social media and urban space has become an important feature of urban regeneration in some regions, but the current research on the virtual-physical relationship and the role of media is not comprehensive. This paper sorts out three paths: “from reality to illusion”, “from illusion to reality”, and “mixed reality and illusion”, and constructs the virtual-physical interaction framework to investigate the evolutionary mechanisms of urban regeneration. Through an empirical analysis of Chaotiangong Street, three fundamental mechanisms are identified. First, spatial transformation progresses from virtual symbolic construction to physical embodied engagement, initiating decentralized regeneration that evolves into serial revitalization through the mutual reinforcement of physical clustering patterns and virtual hotspot linkages, ultimately consolidated by media-gaze-enabled multi-stakeholder governance. Second, social media operates dualistically as both a transmission channel disseminating spatial narratives (public aspirations, commercial strategies, tourist identities, and policy agendas) and an algorithmic apparatus shaping place perception through virtual-physical hybridization. Third, social media has invigorated market vitality, promoted public participation, and attracted policy attention. It has transformed urban renewal from being fragmented to integrated, and from a bottom-up approach to a model of collaboration between top-level and grassroots efforts, which should be guided and advanced in an orderly manner.
