本文在晚近以来移动网络、人工智能掀起的新一轮新技术、全球化浪潮的历史场景 中，聚焦“打卡”“自拍”等短视频影像实践中的典型经验，探讨新媒体时代的城市影 像如何重塑了人与世界的关系，进而拓展了传播、媒介的涵义。本文认为，短视频是数 字时代的典型影像实践，它突破了媒介表征论，凭借突出的涉身性渗透在赛博城市的肌 理中，成为建构社会现实的强大视觉性力量。作为一种存在方式，它确认了在实体与虚 拟世界双重存在的新型自我：我拍故我在。作为一种具身化媒介实践，它汇聚大众的个 人印迹塑造了公共的城市形象：我们打卡故城市在。

Against the backdrop of new technological changes and globalization, supported by the boom of mobile network and AI, this study focuses on “card-punching” and “selfie-taking” as typical short-video image practices to explore how city imaging in the new media era reshapes the nexus between human being and the world, thereby broadening the signifcance of communication and media. This study posits that short-video based image practices break the premises of media representationalism. By building embodiness into the texture of cyber cities, these practices evoke powerful forces of image to construct social reality. As a mode of being, they establish the self that exist both in actual and virtual realms: I photograph, therefore I am has become the motto. As an embodied form of media practice, they pool individual tracks from the masses to re-build a public city image: Supporting the claim that we card-punch, therefore the city is.
