Structural Equation Modeling Applied to Internet Consumption Forecast in Brazil

Abstract

The growth of Internet services over the past few years has increased the importance of Internet consumption forecasting models in telecommunications network planning activity. Most of these models use historical data of variables that, when reduced in size, form context variables: economic, innovation, technology, and Internet supply. Although they include multiple context variables, the techniques employed in using these models are limited to the analysis of a single dependency relationship. Thus, these models fail to understand the interrelationships between context variables and their effects (direct and indirect) on Internet consumption. This research uses Partial-Least-Square Structural Equations Modeling to understand Internet consumption in Brazil between 2002 and 2017. The results show, for example, that the economic context produces direct effects in the context of innovations and indirect effects in the context of technologies and Internet consumption. These results contribute to increase the knowledge of the relationships between the context variables that influence Internet consumption, providing inputs for the development of more accurate forecasting models, thus contributing to the activity of telecommunications network planning.INDEX TERMS Structural equation modeling, internet consumption, telecommunications networks planning.

“…-the living conditions of the population [26,27]; -health, and social well-being [28]; -the levels of technology and innovation [28][29][30]; -environmental sustainability [31]. Of course, composite indicators have also been widely used in the economic area to represent:…”

Economic analysis through alternative data and big data techniques: what do they tell about Brazil?

“…In turn, factors associated with Research, Development, and Innovation influence and are influenced by economic and technological factors (Libório et al 2020a , b ). Broadband Internet access positively impacts labor productivity and is strongly associated with economic indicators such as gross domestic product and employment levels in the economy (Holt and Jamison 2009 ; Gruber et al 2014 ; Li and Forzati 2018 ; Gallardo et al 2021 ).…”
