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.

本文的目的是提出一种量化方法，以计算 ICT 部门对经济的结构性影响，重点关注希腊的案例。我们根据最新的希腊投入产出表和国家层面的结构性商业统计数据，使用假设提取方法构建了一个复合部门。我们的框架建立在经合组织提供的 ICT 行业正式定义的基础上，包括两个不同的子组件，即 ICT 制造和 ICT 服务。在本研究的第二阶段，我们使用基于投入产出和基于网络分析的指标来探索 ICT 服务、ICT 制造业和希腊其他产业之间的生产联系，这些指标建立在扩大的投入产出的中间交易之上包括这两个部门的希腊经济表。我们的实证研究结果表明，整个 ICT 部门在 GDP 和就业方面对希腊经济做出了重大贡献，但这主要是由 ICT 服务部分驱动的。我们进一步发现，与 ICT 制造业相比，ICT 服务在希腊生产网络中的整合程度更高，但它们的生产联系在对其他行业活动的有意义贡献方面表现不佳。这些结果反映了数字技术的低集成度，可以进一步纳入关于希腊经济的 ICT 缺陷以及有针对性的监管和金融干预的必要性的讨论。我们进一步发现，与 ICT 制造业相比，ICT 服务在希腊生产网络中的整合程度更高，但它们的生产联系在对其他行业活动的有意义贡献方面表现不佳。这些结果反映了数字技术的低集成度，可以进一步纳入关于希腊经济的 ICT 缺陷以及有针对性的监管和金融干预的必要性的讨论。我们进一步发现，与 ICT 制造业相比，ICT 服务在希腊生产网络中的整合程度更高，但它们的生产联系在对其他行业活动的有意义贡献方面表现不佳。这些结果反映了数字技术的低集成度，可以进一步纳入关于希腊经济的 ICT 缺陷以及有针对性的监管和金融干预的必要性的讨论。
