The descriptive side, which was based on previous and contemporaneous studies that dealt with the same subject, the quantitative second, which was based on econometrics through the use of the multiple linear regression model, and thus the economic interpretation of the results of the quantitative analysis to evaluate the applied side of the research. The study included the most important conclusions reached by the researchers, the most important of which are: The low exchange rates have positive effects in encouraging exports and reducing the volume of imports and creating an investment environment to attract new investments while increasing the value of the currency, the volume of exports will decrease with an increase in imports leading to dumping the market goods and goods Importing and competing for local products especially if those products are of better quality than local and at a lower price which reduces investment as well as the withdrawal of investors from continuing especially in the agricultural sector. Therefore, the researchers recommend: re-evaluation of local exchange rates and Floating by leaving it to be determined on the basis of the mechanisms of the market in the light of its purchasing power and not to exaggerate its role in encouraging exports and reduce imports and create a favorable investment environment.
