Abstract: 【Purpose/significance】Clarifying the dimensions of user experience of government APPs is crucial for improving public sat‑ isfaction and promoting the digital transformation of government services.【Method/process】Taking the "Suihaoban" APP as an ex‑ ample, this study discovered anomalies during APP usage through screen recording experiments. The user experience dimensions were identified based on the questionnaire survey. The existing issues and causes were analyzed through in-depth interviews, before the op‑ timization strategies were finally proposed.【Result/conclusion】Process experience, performance experience, efficiency experience, trust experience, and interface experience constitute a comprehensive government APP user experience framework.【Innovation/limita‑ tion】The study has introduced user experience theory and constructed a comprehensive government APP user experience framework through multiple methods, exploring the dimensions of user experience and providing a new perspective and theoretical foundation for government APP optimization. Practically, several optimization strategies are proposed to help promote the precise, personalized, and efficient development of government APPs to maximize the social benefits of e-government.
