How Streetscape Design Shapes Everyday Street Vitality: The Mediating Role of Commercial Satisfaction within a Servicescape Framework
摘要
Everyday streets are fundamental social–spatial units of urban life that support residents, workers, and commuters through routine small-scale commercial services and the social interactions associated with them. The vitality of such streets—manifested primarily in high-frequency consumption-related activities and associated pedestrian presence—constitutes a key component of sustainable and livable cities, particularly in daily-life-oriented urban environments. However, prior research has often treated the impact of streetscape design on street vitality as a direct effect, paying limited attention to the perceptual and cognitive pathways through which physical environments shape commercial activity patterns and pedestrian behavior. Drawing on servicescape theory, this study investigates everyday streets within Wuhan’s Third Ring Road and integrates multiple sources of urban big data—including OpenStreetMap, Baidu Street View images, Dazhong Dianping platform data, and China Unicom signaling data—to construct and test a mediation model linking streetscape design, commercial satisfaction, and commercially driven everyday street vitality. The results indicate that moderate vertical complexity at the streetscape skeleton level enhances commercially driven everyday street vitality via higher commercial satisfaction, whereas excessive enclosure reduces pedestrian activity. At the streetscape skin level, natural elements and pedestrian infrastructure tend to foster vitality when effectively coupled with commercial functions. Among perceptual factors, perceived beauty emerges as the primary perceptual driver, while perceived safety appears to function primarily as a threshold condition. By extending servicescape theory to open urban street environments, this study identifies commercial satisfaction as a critical cognitive–affective nexus linking streetscape design to collectively expressed, consumption-oriented everyday street vitality. The findings offer planning-relevant insights for designing vibrant, human-centered everyday streets oriented toward routine urban consumption.
