Mathematical Methods in Determining Spatial Development Priorities for The Industrial Sector at The Level of The Iraqi Governorates: A Study of Quantitative Measures to Determine Investments in Industrial Urbanization

The levels of development exhibit significant disparities across countries and even among different parts of the same governorates. The major focus of many planners and decision makers was to investigate and analyze the regional variation in development levels. The study aims to examine the regional disparities in investment within the industrial sector throughout the governorates of Iraq. This analysis is not just based on quantitative indicators, but also takes into account the specific investment requirements of each governorate. To overcome this issue, we do the following actions: A mathematical model is constructed to elucidate the regional differences in investment amongst governorates. This model use factor analysis to quantify the association between various variables studied. Utilize the Ridge Regression Model to assess the influence of the factors on the geographical distribution of investment. The study aimed to determine the allocation of investment in the industry sector among the Iraqi governorates. The priorities for distribution were as follows: ''Al-Muthanna'', ''Missan'', ''Wasit'', ''Salahuddinni'', ''Thi-Qar'', ''Diala'', ''Kerbala'', ''Kirkuk'', ''Al-Qadisiya'', ''Al-Anbar'', ''Al-Najaf'', ''Babil'', ''Nineueh'', ''Basrah'', and Baghdad. This allocation aimed to achieve a balanced regional development. The value of the challenge coefficient (R²= 0. 84 and the correlation coefficient) (R= 0. 91), which indicates the strength of the effect of the economic variables on the investment sector. This value is the spatial distribution of industrial investments among the governorates, and this is confirmed by the decrease in the value of (MSE) as it reached 3319. 41, which confirms the increase in the efficiency of the model at (k= 0. 016).
