Driven by the continuous digital upgrading of smart exhibition industries and innovative development of digital tourism, Artificial Intelligence-Generated Content (AIGC) technology has emerged as a novel technical and creative support for modern exhibition space design. Featuring efficient content output, intelligent scenario deduction, and parametric design advantages, AIGC has broken the traditional creative limitations of the exhibition design industry. Taking the whole workflow of modern exhibition space scheme design as the main research framework, this paper categorizes the functional attributes of mainstream AIGC design tools and explores their practical application strategies in the full-cycle design process covering thematic planning, spatial layout planning, visual effect creation, and interactive scene design. By discussing the innovative significance and practical advantages of AIGC technology in exhibition space design, this study provides a solid theoretical basis and feasible practical references for the standardized, in-depth, and intelligent application of AIGC technology in the field of smart exhibition design.
