 In summary, the researchers analyzed various indices related to e-government in the European Union and identified those that could be used in a DEA model to measure the efficiency of e-government related inputs and outputs. They also implemented correlation analysis to verify the selection of inputs and outputs and determined that two models, the CCR and BCC models, were appropriate for calculating the DEA model. Finally, they compared the results from the two models and concluded that the countries of Northern Europe are the most efficient in terms of digitalization, e-government.
