Abstract in Portuguese
Através de um banco de dados de oitenta e quatro milhões de notas fiscais eletrônicas coletadas através de um sistema de auxílio ao compliance tributário digital, são modeladas os seguintes tipos de redes comerciais brasileiras: redes de transações entre empresas, redes de transações entre grupos empresariais, redes de transações entre ramos de atividade econômica e redes de transações entre cidades. Através de técnicas de análise de rede como menor caminho médio, distribuição de graus, coeficiente de agrupamento, medidas de centralidade e detecção de comunidades, procura-se entender as propriedades estruturais que rege a economia brasileira. Este trabalho serve como alicerce para o desenvolvimento de novos estudos relacionados ao entendimento da economia brasileira por meio de redes complexas, abrindo portas, por exemplo, para o estudo de fenômenos como instabilidade de mercado e surgimento de monopólios.

Abstract in English
From a database of eighty four million electronic invoices collected through a software system that helps with digital tax compliance, the following types of Brazilian commercial networks are modeled: inter-company transaction networks, inter-group transaction networks business networks, cross-industry transaction networks and inter-city transaction networks. Through network analysis techniques such as shortest average path, degree distribution, clustering coefficient, centrality measures and community detection, we seek to understand the structural properties that govern the Brazilian economy. This work serves as a foundation for the development of new studies related to the understanding of the Brazilian economy through complex networks, opening doors, for example, to the study of phenomena such as market instability and the emergence of monopolies.
