Multimodal Mechanisms in Urban Image Construction: An Audiovisual Analysis of Gather in Shenzhen

Abstract

This study applies the integrated theoretical frameworks of visual and auditory modalities derived from multimodal discourse analysis (MDA) to systematically investigate the mechanisms of audiovisual synergy in the official promotional film Gather in Shenzhen, produced for the 2026 APEC Economic Leaders’ Meeting. It aims to demonstrate how the interaction between visual and auditory elements constructs a cohesive and multidimensional urban narrative. The analysis shows that the film strategically employs visual and auditory resources to achieve strong thematic consistency across six core themes: vibrant and innovative, comfortable and convenient, green and beautiful, safe and resilient, virtuous and culturally advanced, and smart and efficient. The findings further underscore the pivotal role of four cross-modal synergistic mechanisms, including reinforcement, complementarity, contrast, and juxtaposition, in maintaining discursive cohesion and enhancing emotional resonance. Overall, the integration of visual and auditory modalities effectively presents Shenzhen as a dynamic, welcoming, and technologically advanced global city, thereby strengthening the communicative power of urban promotional media and offering useful insights into the construction of contemporary national and urban images.
