In integration of Turkey to the EU, the scope of regional programs has been transformed to reach the basic regional socio-economic standards of the Union. In this way, new cooperative regional programs have been applied in Turkey by the EU and Turkey. Therefore, some regional programs in Nomenclature of Territorial Units for Statistics （NUTS） level-2 regions have been examined in this study. In this point, the data of regional GDP per capita by sectors has been used to analyze sectoral disparities in terms of Gini index. To discuss and evaluate the future of the programs on regional disparities, related sector parameters of GDP per capita have been calculated by regression analysis through（ balanced） panel data. The findings showed that there is a remarkable sectoral disparity among program regions, and the sector priorities of the programs are not sufficient to bring any long-term solution for the regional disparities. Finally, Turkey from regional and/or multiregional perspectives needs to reconsider the regional programs for decreasing the disparities as much as development of the regions.
