Digital government are transforming governmental structures and institutions. The common institutional arrangement of a multi-level government system (MLG) clearly affected by the increased use of digital government systems within public administration. This is a hierarchical structure structuring powers and resources in which digital government has to be embedded. The outcomes of digitalization in such settings can be different. This argument builds on two previous implementation studies that open for this argument. These studies are here used as illustrations for the theoretical embedding of how digitalization can glue levels of government together. The conclusion is that digital government systems, if used smartly, can function as glue between the levels of government in an MLG system.
