AGGREGATED FINANCIAL CONTRIBUTIONS OF SOME ACTIVITY SECTORS ON NIGERIA’S ECONOMIC GROWTH USING ARDL MODEL

Abstract

The paper examines the aggregated financial contributions of industrial and services sector output on the economic growth of Nigeria using ARDL model. The data sets on gross domestic product (GDP) and industrial and services sector output (measured in billions of naira) cover the period of 1981 to 2019. The ADF unit root test was used to test the order of integration of the variables under study. Applying Generalized Linear Model (Newton-Raphson) method of estimation, the results showed that both the industrial sector (IND) and services sector (SERV) contributed positively to GDP growth both at the short-run and long-run, significant under 5% level and the system is adjusting towards long-run equilibrium at the speed of approximately 102%. Therefore, the government should put more effort in industrial and services sector reforms so as to make these sectors more proactive at improving economic growth in Nigeria.
