Regional Specialisation and Sectoral Concentration in Romania on Local Administrative Units Level (LAU)

This study provides an in-depth examination of regional specialisation and sectoral concentration within Romania, focusing on Local Administrative Units (LAU).Leveraging data from the National Trade Register Office spanning 2008 to 2021, the research analyses various economic indicators, including turnover, employment, company count, and profit or loss accounts, across different sectors according to the NACE rev. 2 classification.These indicators are synthesised at the LAU level, corresponding with the Nomenclature of Territorial Units for Statistics (NUTS) framework.The study employs a suite of specialised and concentration indexes, such as the Herfindahl-Hirschman and Krugman specialisation indexes, to dissect regional economic structures and identify patterns of economic specialisation, diversification, and stability.This investigation elucidates the complex dynamics of regional economic development, offering critical insights for policy formulation, economic strategy, and scholarly discourse on economic integration and structural transformation within the context of Romanian administrative units and beyond.This contribution is pivotal for understanding regional economic patterns, guiding strategic decision-making in economic planning, and fostering sustainable development.
