Urbanization, transportation infrastructure, ICT, and economic growth: A temporal causal analysis

In many countries, urbanization is seen as an important policy tool to ensure sustained economic growth. While urbanization can lead to positive economic outcomes, unfettered migration into urban areas without appropriate infrastructure support such as information and communication technology (ICT) infrastructure and transportation infrastructure can lead to negative side effects such as congestion, formation of slums, and other diseconomies of scale. The latter can actually lower economic growth. This study examines the relationships between urbanization, transportation infrastructure, ICT infrastructure, and economic growth in the G-20 countries from 1961 to 2016. Using the panel vector error-correction model, the study shows that there is a myriad of temporal causal relationships between the four variables in both the short and long run. The key policy implication of these results is that long-run economic growth in the G-20 countries depends on the co-development of policies in creating a vibrant urban ecosystem that is enabled by intelligent transportation systems and underpinned by a sound ICT infrastructure plan.
