Our paper is based on the five principal dimensions of the International Digital Economy
and Society Index (I-DESI), but instead of using the original scoring model based
on arbitrary pre-determined weights, we apply more objective ranking methods that
use the statistical properties of the data series to determine where the Visegrad
Group (V4) countries (Czechia, Hungary, Poland and Slovakia) stand in terms of digital
development among the countries of the European Union and other developed countries
in the data set. The ranking is performed using the DEA-CWA (Data Envelopment Analysis/Common
Weights Analysis) method (with six models) and the TOPSIS (Technique for Order of
Preference by Similarity to Ideal Solution) method. Although the resulting weight
vectors differ significantly from the arbitrary weights set by the European Commission,
the country rankings remain similar, displaying relatively little sensitivity to the
weighting method chosen.
