Abstract in Portuguese
Esta tese tem como objetivo principal avaliar os efeitos dos incentivos fiscais sobre a estrutura de capital e a rentabilidade das companhias abertas brasileiras não financeiras. Sob o aspecto metodológico, este estudo pode ser classificado como do método quantitativo, do tipo descritivo-longitudinal e transversal. A população-alvo do estudo são as companhias abertas brasileiras não financeiras, cuja amostra é composta por aquelas que têm ações negociadas na Bovespa, totalizando 590 empresas, perfazendo um número potencial de registros contábeis de 7.670 no período de 1995 a 2007, cujos dados foram obtidos no banco de dados da Economática. Na análise transversal, os indicadores de incentivo fiscal, estrutura de capital e rentabilidade, para cada empresa, foram reduzidos aos seus valores médios. A comparação dos referidos indicadores nos grupos sem e com incentivos fiscais foi realizada por meio do teste U de Mann-Whitney para amostras independentes, com utilização da Análise de Homogeneidade (HOMALS) na construção de mapas perceptuais e realização do procedimento GLM Univariate Test para avaliar o efeito da obtenção de incentivos fiscais sobre aqueles indicadores. Na análise longitudinal, considerou-se o procedimento GLM Multivariate Test na avaliação do efeito da obtenção de incentivos fiscais e do ano em que a operação contábil foi realizada sobre os referidos indicadores. Os resultados do estudo sugerem não haver correlação estatisticamente significativa entre incentivo fiscal e indicadores de estrutura de capital. Por outro lado, identificou-se correlação estatisticamente significativa entre incentivo fiscal e rentabilidade das empresas.

Abstract in English
The main goal of this research is to evaluate the effects of the tax incentives on the capital structure and the profitability of the Brazilian non-financial public companies. Under the methodological aspect, this study can be classified as a quantitative method, in the longitudinal-descriptive and transversal type. The target population of the study is the Brazilian non-financial public companies, which the sampling is composed by those that have stock negotiated in the Bovespa (the Brazilian trading market in São Paulo), totalizing 590 companies, amounting to a potential number of 7,760 registers during the period of 1995- 2007, which data were obtained in the data bank of Economática. In the transversal analyses the tax incentive indicators, were reduced to their average values. The comparison of the above-mentioned indicators in the groups with and without incentive was done by the test U of Mann-Whitney for the independent sampling, by the usage of the Homogeneity Analysis (HOMALS) in the construction of the perception maps and the accomplishment of the GLM Univariate Test procedure to evaluate the effect of obtaining the fiscal incentives under these indicators. In the longitudinal analyses was considered the procedure GLM Multivariate Test in the evaluation of the effect of obtaining the tax incentives and of the year that the accounting operation was done under the referred indicators. The results of the study suggest that there are no meaningful statistical correlation between the tax incentive and the capital structure indicators. On the other hand it was found a meaningful statistical correlation between the tax incentive and the profitability of the companies.
