Trade Intensity In Digitally Delivered Services And Economic Complexity

Purpose. Digitally delivered services have become a pivotal component of global trade, accounting for over 50% of total services exports worldwide as of 2020 (Mourougane, 2021). But how is this digital trade related to the structure of an economy? Despite the growing significance of digital trade, the relationship between trade intensity in digitally delivered services and the structure of an economy remains underexplored (Mourougane, 2021; Dong and Xu, 2022; Zhou et al., 2023; Chiappini and Gaglio, 2024). In this paper, we fill this research gap by examining how exports per capita of digitally delivered services relate to multidimensional economic complexity, encompassing measures for the trade and research structure of an economy (Stojkoski et al., 2023). Understanding this relationship is crucial for policymakers and stakeholders aiming to enhance competitiveness in the digital economy (Hidalgo and Hausmann, 2009; Hausmann et al., 2014; Hartmann et al., 2017; Hidalgo, 2021; Romero and Gramkow, 2021). Design/methodology/approach. We employ a panel regression analysis with time-fixed effects to control unobserved heterogeneity and temporal dynamics across countries and over time. We follow the Handbook on Measuring Digital Trade (Mourougane, 2021) and define digitally delivered services as all international trade transactions that are delivered remotely over computer networks. These range from providing online educational services to cloud computing subscriptions (Stojkoski et al., 2024). Using this definition, we collect data from the BATIS WTO dataset on services (Fortanier et al., 2017) and Eurostat mappings (European Commission). Statistical Office of the European Union, 2021) to calculate per capita exports of digitally delivered services for over 120 countries from 2005 to 2020. We also use data on the Economic Complexity Index (ECI) for the research and trade dimensions from the Observatory of Economic Complexity (Simoes and Hidalgo, 2011). These indexes compare the economic structure of a country to an ensemble of other countries, with higher values implying that the country is more sophisticated compared to the ensemble. We then employ panel regression analysis on average data segmented into four four-year periods: 2005-2008, 2009-2012, 2013-2016, and 2017-2022 in which the dependent variable is the log of the digitally delivered services exports per capita. This methodological approach allows us to investigate the correlation between exports per capita and the economic complexity indices derived from trade and research data, and to study their interaction in explaining digital trade. Findings. The analysis reveals a robust positive relationship between economic complexity and digitally delivered services exports per capita (see Table 1 for the regression results). Specifically, according to our final model (including all covariates, Table 1, column 7), a one-unit increase in trade ECI is associated with a 0.733 increase in the log of digitally delivered services exports per capita (p
