Study of Spatial Disparities in Algerian Regions: Using a Parametric and Non-Parametric Approaches

In modern economic development strategies, the achievement of developed regions and create interaction between them in order to make it convergent and cohesion is necessary to reduce disparities. Because there are spatial factors who have driven development . This article attempts to investigate spatial disparities among Algerian regions through the application of parametric and non-parametric methods (principal component analysis, nearest neighborhood and spatial regression) in order to identify the economic structure of regions and study the spatial disparities. The main results of this study indicate the existence of disparities from the lower spatial auto-correlation rate between regions and the heterogeneity tests. In other hand, the insignificant of spatial econometric tests (spatial dependence of error) indicate the independence of Algerian regions, which denoted that the thinking of decision makers on the spatial structure plans of Algerian economic cities is still limited.
