Investigation of Telecommunication Infrastructures-Industrialisation-Growth Nexus: Evidence from Disaggregated Panel Data Analysis

Volume 76 - Issue 2, May 2023
(pp. 209-264)
JEL classification: C33; O30; O14; O47; O55
Keywords: Regional Groupings; Panel VAR-Granger Causality; Telecommunication Infrastructures; Industrialisation; Economic Growth


This study examines the telecommunication infrastructures-industrialisation-economic growth nexus in developing countries over the period 2000-2018. A panel data comprising of 99 developing countries were collected and divided into three sub-regions: Latin American & Caribbean (LAMC), Middle East & North Africa (MENA) and Sub-Saharan Africa (SSA). For the analysis, the newly developed panel VAR in generalized method of moment (GMM) estimation approach was applied. Our findings suggest a long-run equilibrium relationship between the three variables. At the same time, strong evidence of two-way causality among the three variables in the entire sample and regions was reported. The panel VAR results suggest that: (i) telecommunication infrastructures have a negative and positive impact on industrialisation and growth, respectively; (ii) industrialisation has a negative impact on growth which imply the inability of the former to drive the latter across the regions. Thus, there is a need to promote realistic policies that will enhance telecommunications infrastructure, levels of industrialisation and economic growth concurrently in the developing countries/regions.
