Econometrics Analysis of the Impact of Some Selected Economic Services Spending on Nigeria Economy

This study focused on econometrics analysis of the impact of Road and Construction Spending (RCS) as well as Transport and Communication spending (TCS) as selected Economic Services Spending on Nigeria Economy proxy by Gross Domestic Product (GDP) during the period 1981- 2022. The study used time series data like GDP, RCS and TCS sourced from the Central Bank of Nigeria (CBN) Statistical bulletin and National Bureau of Statistics. The data were subjected to Unit root diagnostic test to determine whether they are stationarity or otherwise. The data were integrated of order 1(0) and 1(1), hence, the need for Autoregressive Distributed Lag (ARDL) model and the Error Correction Model (ECM) technique was also adopted to check for the speed of adjustment. The finding reveals that Road and Construction Spending (RCS) as well as Transport and Communication Spending (TCS) have positive and insignificant impact on GDP. Therefore, the researchers recommend that more still need to be done by all ties of government to improve road and communication networks that will enhance sustainable economic growth in Nigeria.
