The implication of savings and investment on economic growth is mixed and controversial both theoretically and empirically. There is large empirical literature which examines the relationship between savings and economic growth in Nigeria. There is also a considerable literature which looks at the relationship between economic growth and investment. However, little attention has been given to examining the implications of savings and investment on economic growth in Nigeria. The aim of this paper is to evaluate the implications of savings and investment on economic growth in Nigeria using ordinary least square regression. Results for ADF and PP unit root tests show that all variables under consideration are I(1). The study also revealed that there is long run relationship between savings, investment and economic growth in Nigeria. The result of the regression indicates that change in gross domestic savings movements has negative and significant effect on the change in economic growth in Nigeria and that the change in gross domestic investment has positive and significant effect on the change in the Nigerian economic growth. We therefore recommend that government should set a sound and fertile environment in order to foster domestic saving that will help to increase the level of economic growth in Nigeria
