The continuous use of users is the key to the success of mobile government. Based on the self-regulation framework, combined with perceived quality, transparency, participation and cooperation degree, a model of influencing factors of intention to continue using mobile government was constructed from the perspective of trust. The structural equation model was used to analyze 354 valid questionnaires collected. The empirical results show that system quality, service quality and information quality have positive effects on trust in technology (TiT). Transparency and collaboration have positive effects on trust in government (TiG), while participation has no effect on government trust. Mobile government trust is significantly positively affected by TiT and TiG, and positively affects users' continuance intention. This paper explores the antecedent variables of trust, enriches the theoretical perspective of the research on users' continuous usage intention, and provides practical suggestions for improving the sustainable use rate of mobile government.
