Abstract: This Study aimed to examine the relationship between the savings rate and the investment rate in the Algerian economy during the period (1970-2011). In order to improve whether the time-series variables stable or not, it is required the use of certain statistical tools, in addition to the unit root tests, were also identified integration rank each variable separately. It turns out that the variables integrated first-class, and in the light of this, Co-Integration test was used for each of the joint method Engle - Granger and Johansen method, in addition to our use of the methodology of Granger causality, in order to verify the existence of a long-term relationship between the two. It was evident from the analysis the lack of equilibrium relationship between savings and investment in the Algerian economy during the period of the study. The probably explanation for this is due to the nature of the national economy, which is heavily based on the hydrocarbon sector as a major source of the national income and the foreign exchange, and lack of diversity of economic activity and the structure of exports on one hand, and to weakness capacity of the national economy on the other.
