Citizens' Trust, E-Government, and Government Performance

E-government has become a central instrument for transforming public governance. Despite its growing importance, limited research has examined how e-government website quality shapes the relationship between citizens' trust in government and perceptions of government performance. This study investigates the mediating role of e-government website quality—operationalized through information quality, service quality, and system quality—within the extended DeLone and McLean IS success model (2003, 2004), drawing on Teo et al.'s (2008) framework. Analyzing survey data from Korean citizens (n = 1,015), we find that citizens' trust is positively associated with all three quality dimensions, but only information quality significantly mediates the trust–performance relationship. This mediation is stronger among e-government users and absent among non-users, underscoring the pivotal role of informational clarity and accuracy in translating trust into enhanced perceptions of government performance.
