Statistical Modeling of Development Gaps in the Counties of Iași and Sibiu

Summary/Abstract: This study explores regional development disparities between the counties of Iași and Sibiu, focusing on the period 2004–2024, which was marked by integration into the European Union and significant economic restructuring. The main objective is to identify structural disparities using indicators of economic performance, demographics, and infrastructure. The methodology adopted is quantitative, based on the analysis of validated data series from the INESSE TEMPO-Online database, using SPSS software. The study includes 21 annual observations for each county, applying T-tests, Pearson correlations, and linear regression models. The results indicate the existence of statistically significant disparities where p < 0.05. Therefore, although Iași has a significant demographic and academic advantage, Sibiu demonstrates superior labor market efficiency, with a much lower unemployment rate and a greater capacity to generate value added through the industrial sector. In this regard, the study highlights the crucial role of road infrastructure and foreign investment in reducing regional disparities.
