Efficiency of Digital Economy in the Context of Sustainable Development: DEA-Tobit Approach.

The paper aims at measuring the efficiency of the digital economy in EU countries. For that purpose, data envelopment analysis (DEA) is used. Sub-dimensions of the Digital Economy and Society Index (DESI) are used as inputs and the Sustainable Development Goals Index (SDGI) as an output. The results revealed that Bulgaria, Italy and Romania are the most efficient digital economies in terms of human capital; Belgium, Bulgaria, Cyprus, Croatia, Estonia, Finland, Greece, Lithuania, Poland and Portugal in terms of connectivity; Bulgaria, Hungary and Romania in terms of integration of digital technology; and Romania in terms of digital public services. The result of tobit regression analysis showed that not all the indicators of the DESI dimensions positively influence the efficiency of the digital economy. [ABSTRACT FROM AUTHOR]
