In historic and cultural districts characterized by the coexistence of residential and commercial functions, street spaces play a pivotal role in shaping urban cultural continuity and local identity. They simultaneously support the daily lives and emotional attachment of residents while accommodating the tourism activities of visitors. Despite this dual significance, the distinct functional and experiential expectations of residents and tourists have resulted in multidimensional perceptual differences, which have not been sufficiently addressed in previous studies yet are crucial for enhancing street space quality. Using the Sajinqiao Historic and Cultural District in Xi’an, China, as a case study, this research develops a perceptual evaluation system for street spaces and applies an enhanced IPA-KANO model to examine variations in explicit importance, attribute performance, and implicit importance between residents and tourists. Findings indicate that residents attach greater importance to religious sites, community facilities, and cultural belonging, whereas tourists prioritize transport accessibility, iconic architecture, and commercial vibrancy. Both groups expressed relatively low satisfaction with several key cultural experience elements. Based on these results, this study proposes targeted optimization strategies for elements identified as highly important yet underperforming, providing a practical framework for balancing heritage conservation with contemporary tourism development in such integrated urban environments.

Amid urbanization, historic districts serve as key carriers of urban cultural memory, confronting dual challenges of integrating tradition with modernity and balancing cultural inheritance with spatial renewal. Enhancing residents’ satisfaction with cultural spaces is crucial for improving their quality of life and promoting the sustainable development of urban culture. However, existing research lacks systematic analysis of the intrinsic relationship between residents’ needs and spatial satisfaction, focusing on holistic conservation or spatial design. Using ERG Theory and taking Longweiguan Historic and Cultural District in Dali, China, as the case, this study explores how residents’ needs and cultural space satisfaction interact via theoretical construction and empirical analysis. It establishes a 20-index satisfaction evaluation system, adopting field surveys, in-depth interviews and Structural Equation Modeling (SEM) for quantitative analysis. Findings: (1) Residents reported moderate-to-high overall satisfaction with cultural spaces, where relatedness needs demonstrated the most significant impact on satisfaction, while growth needs scored lowest. (2) Existence needs directly affect satisfaction through basic elements like spatial safety and indirectly strengthen relatedness needs. (3) Cultural industry spaces hinder satisfaction due to disconnected innovation and resident participation. Thus, a “safety–social interaction–innovation” strategy is proposed to support the living conservation and sustainable development of historic districts.

Traditional village resilience is shaped by interactions among ecological foundations, cultural continuity, and social functioning, yet cultural resilience and the coordination and constraints among internal subsystems remain insufficiently understood. This study evaluated 16 sampled traditional villages in the northern foothills of the Qinling Mountains, Xi’an, China. Based on the theory of cultural ecology and the pressure–state–response framework, an ecological–cultural–social resilience evaluation system was developed. The coupling coordination degree model, obstacle degree model, and two-step cluster analysis were applied to examine overall resilience, subsystem coordination, and obstacle patterns. Results reveal differences in overall resilience among villages and clear asynchronous characteristics among ecological, cultural, and social subsystems, with cultural resilience showing the greatest inter-village variation. Ten villages fall into the barely coordinated level, five reach the primary coordination level, and one achieves intermediate coordination. Under the combined weighting scheme, the cultural subsystem is identified as the dominant obstacle dimension in 13 villages, while three exploratory obstacle patterns are observed based on subsystem constraint combinations. Sensitivity analysis indicates that overall resilience rankings are generally stable, whereas dominant obstacle identification shows some sensitivity to weighting schemes. These findings support differentiated conservation and resilience enhancement by integrating overall resilience, subsystem coordination, and constraint structures.
