This paper presents a quantification approach for calculating the structural effects of the ICT sector in the Greek economy. The study finds that the ICT sector, particularly the ICT services component, has a significant contribution to the Greek economy in terms of GDP and employment. However, ICT services are more integrated in the Greek production network compared to ICT manufacturing, but their production linkages are underperforming in terms of contributing meaningfully to other sectors.
The aim of this paper is to present a quantification approach for the calculation of the ICT sector's structural effects in the economy, focusing on the case of Greece. We construct a composite sector using a hypothetical extraction methodology based on the most recent Greek input-output table and structural business statistics at the national level. Our framework builds on the formal definition of the ICT sector provided by OECD and includes two distinct sub-components, ICT manufacturing and ICT services. In the second stage of this study, we explore the production linkages among ICT services, ICT manufacturing and the rest of the Greek industries using input-output-based and network analysis-based metrics that build on the intermediate transactions of an expanded input-output table of the Greek economy that includes the two sectors. Our empirical findings suggest that the total ICT sector has a major contribution to the Greek economy in terms of GDP and employment, but this is driven mainly by the ICT services component. We further identify that ICT services are more integrated in the Greek production network compared to ICT manufacturing, but their production linkages are underperforming in terms of meaningful contribution to the activity of the rest of the sectors. These results reflect the low integration of digital technologies and can be further embedded in a discussion on the ICT deficiencies of the Greek economy and the need for targeted regulatory and financial interventions.
