Ensaios sobre a Economia do Rio de Janeiro: uma abordagem de redes complexas

Abstract

The study, divided into two essays, analyzes the economy of the state of Rio de Janeiro through a Complex Input-Output Network (RIP), revealing structural characteristics of the input-output matrix of Rio de Janeiro. Using data from 2015, the research identifies the interdependencies between 22 economic sectors of the city of Rio de Janeiro (R1), the metropolitan region (R2) and the state of Rio de Janeiro as a whole (R3). The analysis shows the relevance of the extractive and manufacturing industries, in addition to the trade in services sector, especially the so-called industrial services of public utility (SIUP), which are distributed throughout the territory of Rio de Janeiro. We also identify the significant participation of the services sector, including commerce, transportation, financial and scientific activities. These are the most significant generators of forward (weighted degrees of output in RIPs) and backward (weighted degrees of input in RIPs) linkages. Although it is the second largest state GDP in Brazil, the production matrix of R3 has weaknesses resulting from the concentration of production and dependence on specific sectors. The results of the RIPs highlight key sectors with high potential for disseminating positive economic externalities, which are important for the development of economic diversification strategies, as well as for regional strategic planning. The results also suggest that intersectoral relationships of the RIPs can be useful in understanding and analyzing network resilience, which contributes to overcoming the economic challenges of the three regional levels analyzed. In addition, we hope that they can contribute to the quality of public policy decisions that promote sustainable growth of the economy of Rio de Janeiro.
