Public Perceptions of Emergency Language Services: Importance–Performance Analysis from an Urban Resilience Perspective in Xi’an Chanba International Port, China

Accessible emergency information supports inclusive urban resilience. This study examines public perceptions of emergency language services (ELS) in Xi’an Chanba International Port, China. A cross-sectional convenience sample of 318 respondents completed a 22-item paired importance–satisfaction questionnaire. Exploratory factor and parallel analyses suggested five dimensions for both rating scales. Analyses included paired tests, data-centered importance–performance analysis (IPA), 5000 bootstrap resamples, and exploratory covariate-adjusted linguistic inclusiveness (LI) comparisons. Importance exceeded perceived performance for all five LI attributes. Frontline language skills for communicating with foreign nationals, intelligent language technologies, and simultaneous dissemination across channels had Concentrate Here stability rates above 99%; accessible support and routine training were boundary cases. Adjusted comparisons did not provide robust evidence of LI rating differences across the recorded language and hukou/identity categories. The findings provide a public-perception baseline for targeted consultation and scenario-based service assessment.
