Matriz insumo-produto no estado do Ceará: uma análise de encadeamentos

Abstract

The present work proposes to analyze structurally the relations between the sectors of the economy of Ceará using the input-output matrix. This analysis focuses on the degree of dependence that each sector has on the others (behind in the productive process), which reveals its importance in the productive chain. It is intended, therefore, to identify the proportion of sectors that are classified as chained in the economy. The analysis also looks at the dependence of groups of sectors allocated by nature of the activity. The input-output matrix of the state of Ceará produced by the Instituto de Pesquisa e Estratégia Econômica do Ceará (IPECE) with data from 2013 was used. The Hirchman-Rasmussen index was used to identify the sectors that have a link and the index of variability to capture the magnitude of impact. It was noticed that the economy of Ceará presents 41.53% of the existing sectors in the input-output matrix chained. With regard to the group of sectors, all the sectors related to energy present themselves as chained; of the transport sectors, 83.33% are linked; the same proportion for services and direct production is 42.85% and 42.10%, respectively; of those related to creation, 33.33%; and none of the sectors related to cultivation/agriculture/fishing/extraction is chained.
