Infrastructural development and economic growth in Nigeria

Abstract

The paper examines the empirical investigation between infrastructure facilities and economic growth in Nigeria using time series data that spans 1990 to 2020. The estimating technique is the Autoregressive Distributed Lag (ARDL) model. The indices of infrastructure are electricity, telecommunication technology and road transportation infrastructure. Real Gross Domestic Product is used to proxy economic growth. Two models are estimated. In the first model there is positive significant relationship between power sector and growth and negative significant relationships between both the road transportation and telecommunication on one hand and economic growth on the other. The second model is to show the influence of only telecommunication infrastructure on growth and it gives the desired result. It is therefore expedient for government to take steps at improving the development of infrastructure in order to contribute to economic growth. The government is also advised to evolve a policy of maintaining these infrastructures for longevity of the infrastructural facilities.
