Abstract

Este estudo investiga a integração das Regiões Geográficas Intermediárias (RGInt) de Minas Gerais (MG) com base nos fluxos comerciais inter-regionais e no multiplicador de produção regional. Utilizando uma Matriz Insumo-Produto (MIP) inter-regional estimada para 2019, mapeiam-se os fluxos entre as 13 RGInt, identificando vantagens competitivas e efeitos de polarização/propulsão. Os resultados indicam que, apesar da competitividade em setores como o agronegócio, a economia mineira é regionalmente desarticulada, com baixa integração produtiva. A cadeia metalomecânica mostra potencial integrador, ainda que centralizado em Belo Horizonte (BH), enquanto a cadeia da moda apresenta articulação limitada. A heterogeneidade produtiva e a concentração de setores tecnológicos restringem sinergias regionais. O estudo destaca a importância de políticas públicas para adensar cadeias estratégicas do estado. This study investigates the integration of the Intermediate Geographic Regions (Regiões Geográficas Intermediárias – RGInt) of Minas Gerais (MG) based on interregional trade flows and regional output multipliers. Using an interregional Input-Output Matrix (IOM) estimated for 2019, the study maps the flows among the 13 RGInt, identifying competitive advantages and polarization/propulsion effects. The results indicate that, despite competitiveness in sectors such as agribusiness, the economy of Minas Gerais is regionally fragmented, with low productive integration. The metalworking supply chain shows integrative potential, although it remains concentrated in Belo Horizonte (BH), while the fashion supply chain exhibits limited regional articulation. Productive heterogeneity and the concentration of technological sectors constrain regional synergies. The study highlights the importance of public policies to strengthen strategic value chains in the state.
