Given that e-government gives birth to the transformation of government, how can that transformation result in and enhance citizens' trust in their government?
Transformation of government also need to involve citizens as stakeholder. By doing so then you can grantee the trust. Other wise transforming without citizen involvement of citizens my end up citizen increasing the gap between the government and citizens, and this will lead to no trust as they are not part of anything going on in the government side.
In this report you can find a very analytical discussion which adderesses the problem of e-govenrmetn and trust in government:
Avgerou, C.; Ciborra, C.; Cordella, A.; Kallinikos, J; Smith, M. "The role of information and communication technology in building trust in governance: Towards effectiveness and results" Inter-American Development Bank. (2005).
E-government can mean so many different things from making information available online to e-voting, and all will have different impact. For instance, in one of our recent study, we found - both experimentally and based on election survey - that e-voting makes people less efficacious and more negative towards politicians rather than the other way round.
