长期以来，实体空间这一因素常常在主流传播学研究中被忽视。近十几年来，传播理论的空间转向催生了“空间媒介”的话语建构，空间从一种边缘性概念成为建构现实的重要力量，空间媒介化成为研究的热点。随着城市化进程的推进，城市中涌现出各具特色的空间形态。这些空间不仅涵盖了公共场所、住宅区和建筑群等具有公共属性的领域，同时也包括了商圈、酒店和咖啡厅等充满商业气息的场所。在此背景下，传播学领域逐渐兴起了“城市空间媒介化”的研究视角，探讨这些空间如何作为媒介载体，在信息传播和社会互动中发挥着重要作用。
本文选取广东省深圳市的夜市作为研究对象，以“白石龙公园夜市”作为个案展开研究，通过质性研究的方法，以列斐伏尔的空间三元辩证法为理论切入，将城市空间的主体分为感知的空间、构想的空间和生活的空间三部分，进一步探究深圳夜市与深圳城市形象的互动关系。研究发现，深圳夜市不仅是市民日常生活不可或缺的组成部分，更是深圳多元文化交融和经济繁荣的生动缩影。深圳夜市作为一种空间媒介，其背后蕴含的符码意义、文化特质都深植于深圳市民的日常生活，构成了这个城市的精神气质，塑造了深圳市年轻活力、多元包容的城市形象，打造了积极的城市名片，推动城市的持续健康发展。
在此基础上，针对当前都市居民普遍面临的心理疏离和文化同质化问题，本文基于空间媒介化和城市传播的双重视角，提出了深圳夜市在促进居民地方认同和城市形象传播方面的策略。具体而言，深圳夜市应当在象征符号的展示、媒介矩阵的打造、在地情感的连结三个方面作出进一步努力，推动深圳城市形象传播、提升城市的文化软实力。

For a long time, the factor of physical space has often been neglected in mainstream communication studies. In the past decade or so, the spatial shift in communication theory has given rise to the discourse construction of "spatial media", and space has become an important force in the construction of reality from a marginal concept, and the mediation of space has become a hot topic of research. With the advancement of urbanisation, a variety of distinctive spatial forms have emerged in cities. These spaces not only cover public places, residential areas and building complexes with public attributes, but also include commercial places such as shopping districts, hotels and cafes. Against this background, the field of communication studies has gradually developed the research perspective of "mediatisation of urban space", which explores how these spaces play an important role in information dissemination and social interaction as media carriers.
In this paper, the night market in Shenzhen City, Guangdong Province is selected as the research object, and "Baishilong Park Night Market" is taken as a case study. Through the qualitative research method and Lefebvre's spatial triadic dialectic as the theoretical entry, the main body of the urban space is divided into three parts: the perceived space, the conceptualised space, and the living space, so as to further explore the relationship between Shenzhen night market and Shenzhen's urban image. night market's interaction with Shenzhen's urban image. It is found that Shenzhen night market is not only an indispensable part of citizens' daily life, but also a vivid microcosm of Shenzhen's multiculturalism and economic prosperity. As a spatial medium, the symbolic meaning and cultural qualities of Shenzhen night markets are deeply rooted in the daily life of Shenzhen citizens, constituting the spiritual temperament of the city, shaping Shenzhen's young, dynamic, diversified and tolerant urban image, and creating a positive urban business card that promotes the city's sustained and healthy development.
On this basis, in response to the psychological alienation and cultural homogenisation problems commonly faced by urban residents, this paper proposes strategies for Shenzhen night markets to promote residents' local identity and the dissemination of the city's image based on the dual perspectives of spatial mediatization and urban communication. Specifically, Shenzhen night markets should make further efforts in the display of symbols, the creation of a media matrix, and the linking of local emotions, so as to promote the dissemination of Shenzhen's urban image and enhance the city's cultural soft power.
