Regional fiscal disparities is an academic concept and research area focused on the uneven distribution and availability of financial resources, revenue-generating capacity, and public expenditure across different sub-national regions within a country or jurisdiction. It investigates the causes, manifestations, and consequences of these inequalities, examining how variations in economic base, tax capacity, public service provision, and intergovernmental fiscal relations contribute to differing levels of fiscal health and capacity among regions. Key characteristics include differences in per capita revenue, expenditure levels, tax burdens, and the capacity to fund public services, often manifesting as significant inequalities between urban and rural areas or across different levels of development. Understanding these disparities is crucial for analyzing regional inequality, evaluating the effectiveness of fiscal policies, and designing interventions aimed at promoting balanced regional development and social equity.
