Designer UGC (user-generated content) communities serve as the epicenter of contemporary innovation and creativity, offering a platform for a broad design community to showcase their talents, communicate, and collaborate. Grounded in Self-Determination Theory, this study constructs a research model aiming to delve deeply into the underlying driving factors influencing users’ intention to share their works within these communities. Through online surveys targeting UGC community users and employing structural equation modeling, this research validates the determinants affecting their sharing intentions and dissects the pathways of each influencing factor. The findings reveal that in designer UGC communities, factors such as autonomy, competence, relatedness, online social support, and value fit have a significant positive impact on users’ intention to share their works. This study offers profound insights into the intrinsic logic behind user behaviors in the design creativity domain, also providing robust guidance for the operation and management of online community platforms.

Urbanization's swift advance has positioned outdoor advertising as a vital medium in defining city image, highlighting the urgent need for an aesthetic perception evaluation system for city outdoor advertising. This research aims to develop such a system, providing actionable insights to guide the enhancement of the aesthetic experience of city outdoor advertising. To this end, we identified the factors affecting the aesthetic perception of outdoor advertising in cities through literature, interviews, and questionnaires. We then explored the commonalities and differences in perception judgments between residents and tourists, as well as their priorities for improving the aesthetic perception of city outdoor advertising, using the Kano model and the two-dimensional quadrant analysis of the Satisfaction Increment Index (SII) - Dissatisfaction Decrement Index (DDI). The result reveals that residents and tourists hold distinct perceptions regarding "clear and understandable information" and "offer multilingual support" However, there is a consensus between the two groups on other factors influencing aesthetic perception. Additionally, the research highlights disparities in their priorities for improvement. For residents, "clear and understandable information," "engaging and entertaining," "cultural adaptability," "environmental adaptability," and "provide social service information" are of greater importance. In contrast, tourists place a higher value on "rapid responsiveness." These findings provide theoretical support and practical guidance for urban planners and outdoor advertising designers.

In the evolving discourse of affective urbanism, emotions are increasingly recognized as fundamental, systemic drivers shaping the social, perceptual, and symbolic dimensions of urban space. Meanwhile, advances in visual technologies and media aesthetics have transformed contemporary cities into visually saturated environments, where visual cues actively influence how urban space is perceived, navigated, and emotionally experienced. While prior research has addressed affective belonging and spatial identity, these studies often treat emotion and visual design as separate influences rather than examining their interdependent, systemic roles. To address this gap, this study develops an emotion-driven systemic model to analyze how visual design activates affective pathways that contribute to the sustainable construction of place branding. Drawing on survey data from 134 residents in Wuxi, China, we employed Partial Least Squares Structural Equation Modeling (PLS-SEM) to examine the interrelations among emotionally durable visual design, urban emotion, and place branding. The results reveal that visual attachment design (VAD) significantly strengthens place branding through emotional mediation, while visual behavior design (VBD) directly enhances sustainable branding by fostering participatory engagement even without emotional mediation. In contrast, visual function design (VFD) demonstrates limited impact, underscoring its insufficiency as a stand-alone strategy. These findings underscore the value of modeling emotionally durable visual communication as a system that links emotion, behavior, and identity in citizen-centered place branding.
