The overall objective of the MUTEIS project is to explain and understand functional and spatial diversity in Europe's digital economy both from a macro and local/urban perspective. We want to improve knowledge of the macro economic impact of the digital economy, but also on the origins and causes of local diversities in the development of the digital economy as we believe that the urban stories help to understand the macro-overall pattern. The analysis should improve the design and implementation of policy action on European, national and urban levels that efficiently and effectively help Europe's transition into the digital economy in a sustainable way.
