O presente trabalho tem como objetivo fazer uma análise sistêmica do setor de serviços e, para tal, faz uso de técnicas de insumo-produto. Para isto, algumas atividades pertencentes aos setores de serviços da matriz insumo-produto do ano de 2005 foram desagregadas. Foram utilizados os dados da Pesquisa Anual de Serviços (PAS) e, para que a matriz insumo-produto ficasse consistente, foi aplicado o método RAS. A matriz desagregada foi composta por 65 setores, sendo 24 de serviços. Com a matriz mais desagregada, observou-se que os setores de serviços apresentaram alta capacidade de geração de emprego e baixa capacidade na geração do produto. Destaca-se, também, a inexistência de setores de serviços como setor-chave para a economia. Os setores de serviços mostraram ter, em grande parte, um baixo poder de compra e venda de insumos para o restante dos setores da economia e, na maioria das vezes, a compra e venda se dá de forma concentrada em poucos setores. Percebeu-se que os elos dentro dos setores de serviços se mostraram abaixo da média da economia, enquanto os elos entre os setores industriais mostraram-se muito fortes. Quando foram hipoteticamente retirados os setores de serviços da economia, observou-se que estes impactavam em maior quantidade no produto dos setores industriais, mostrando a importância que os setores de serviços apresentam na economia. A systemic analysis of the service sector in Brazil for the year 2005 :: This study aims to perform a systemic analysis of the service sector in Brazil. For that purpose, some activities of the service sector in the input-output matrices for the year 2005 were disaggregated. We used data from the Pesquisa Anual de Serviços (PAS) and in order to get a consistent input-output matrix we applied the RAS method. The disaggregated matrix was composed by 65 sectors of the economy, 24 being service sectors. With the disaggregated matrix, it was observed that services have had a high employment creation capability and a low product generation capacity. It is worth mentioning the absence of service sectors as key sectors in the economy. Most of the service sectors have a low power of sale and purchase of inputs from the remaining sectors of the economy, and in most cases buying and selling are concentrated in a few sectors. It was shown that the links within the service sectors were below the economy’s average, while the links between the industrial sectors were very strong. When the service sectors were hypothetically removed from the economy, it was noted that their impacts were higher on the industrial sectors’ product, indicating the importance of service sectors for the economy.
