Measurement and analysis of the relationship between the diversity of public revenues and the composition of Iraq's Gross Domestic Products for the period (2004-2023)

The present study aims to analyze the relationship between the diversity of public revenues and the composition of Iraq's GDP by highlighting three basic public revenues approved in the Iraqi general budget. (Zedalis, 2007): (oil revenues, tax revenues, and other revenues), and then measure the extent to which the diversity of the public revenue’s base affects the diversity of GDP by measuring and analyzing the relationship between these revenues and GDP. The importance of the current study stems from the fact that it focuses on the need to diversify the general revenue base to ensure that the necessary financial resources are available to spend on various economic activities. Which in turn provides the development of the composition of the GDP of the state(Fildes, 1988), The study reached several important conclusions in this regard, most notably that the variable tax revenues (TR) had no significant impact on the composition of GDP as it came (Prob) for the variable (0.077) This percentage is greater than 5% which is an indication of the weak contribution of tax revenues to the composition of Iraq's GDP. The following questions can highlight the study problem: Increased reliance on oil revenues will expose the State's macroeconomic structure to the risks of economic shocks affecting the development of economic activity through the impact of GDP on those shocks.
