To achieve the research objectives, the inductive approach was used, relying on its statistical and measurement tools using the statistical program (EVIEWS 9) in order to conduct the required statistical tests. In addition to the descriptive and analytical approach to present the theoretical aspect and analysis of the research variables, the Autoregressive Distributed Lags (ARDL) methodology was used to estimate the relationship in the short and long terms. The research reached an important conclusion, which is that the independent variables explain the dependent variable by (90%) through the R-squared coefficient of determination test, and the existence of a cointegration relationship between the research variables according to the limits test, as the calculated (F) value reached (12.376).)Article
