A influência das Micro e Pequenas Empresas (MPEs) no crescimento econômico regional no Brasil

 This article investigates the role of Micro and Small Enterprises (MSEs) in regional economic growth in Brazil, employing a quantitative approach based on panel data econometrics. Using a balanced panel for the 27 federative units from 2016 to 2021, we estimate robust fixed effects models (Driscoll-Kraay) and dynamic models (Arellano-Bond) to measure the impact of variables such as density, growth, employment, and credit for MSEs on variation of state GDP. The results show a strong positive correlation between the density/participation of MSEs and regional economic growth. We discuss the plausibility of causal interpretations, methodological limitations, and public policy implications. The study concludes that although MSEs play a relevant role in regional economic dynamics, structural barriers persist, limiting their full contribution to regional development.
