Local savings are an essential source for financing sustainable development.

The research aims to examine the effect of the efficiency of local savings on the level of per capita income of GDP. Moreover, it analyzes the potential impact on income distribution in the local community. The research adopts a multi-faceted approach that uses quantitative data to analyze the statistical relationships between the level of efficiency of local savings and the average per capita income from the gross domestic product, as local savings constitute an essential part of the local and national economy. The research starts from the hypothesis that the efficiency of local savings is represented by both the Local resource gap and the financing gap, which impacts the average per capita output and is linked to a causal relationship with the efficiency of local savings. The importance of this significant impact on the average per capita income, as local savings rates, the efficiency of these savings, and the local savings and financing gaps in Iraq were analyzed by cointegration analysis. The most important results showed that increasing the efficiency of local saving is linked to an increase in local investments, thus improving the level of per capita income and that there is a direct relationship between the Local resource gap and the average per capita share of GDP and an inverse relationship between the financing gap and the average per capita share of GDP.
