The impact of public expenditures on regional development in the TRC-3 Region

Regional development disparities in Turkey remain a key focus of public policy. This study examines public expenditures in the TRC-3 Region (Batman, Mardin, Siirt, and Şırnak) between 2009 and 2023, evaluating their impact on regional development using trend and comparative analysis methods. The findings show that there has been an increase in public expenditures directed to the region in recent years, but imbalances in the distribution among provinces persist. While Batman and Mardin have benefited relatively more effectively from public investments, periodic fluctuations have been observed in Siirt and Şırnak. Consequently, it has been revealed that sustainable development in the TRC-3 region depends not only on the transfer of resources but also on the quality of expenditures, their strategic orientation, and their implementation based on local needs.
