Abstract
The study aims to study the developments in the government expenditure in Iraq during the period 2003-2017, through analyzing the structure of government expenditures according to the economic division, the changes that have occurred and trying to identify the causes thereof, as well as determining the interaction factors among them in determining the amount of public expenditure (The approved variable). In order to access the research methodology, statistical programs (Minitab, E-views) were used. The statistical results showed that the data are stable at the level as is the case with the growth of government spending and the rate of economic growth and population growth rate, while other variables such as inflation rate and the level of corruption and world prices of oil has become static or stable after taking the first difference. In order to reach the goal of the research, a standard model was estimated to include independent variables (oil prices, GDP growth rate, population growth rate, inflation rate, corruption). The research found a number of results, the most important of which is that the rate of economic growth has had a significant effect on the rate of growth in public spending in Iraq and is in direct relationship with him. The rate of inflation in the Iraqi economy was inversely proportional to the rate of growth in the volume of public spending, and identical to economic logic.
