In the last four decades, in particular, the Brazilian countryside has been showing a new dynamic in its population and activities, which leads to a new configuration. This new setting can be observed with respect to the occupation of the people in rural areas, with fall of the number of persons employed in agricultural activities with rural residence in the 21th century. Noting the new rural setting to the states of São Paulo, Paraná, Mato Grosso do Sul, Mato Grosso and Goiás, noted that they have presented the aforementioned phenomena. However, the dynamics of rural occupation in Brazil does not occur homogeneously. That said, we seek to, through this thesis, analyzing the distribution and determinants of agricultural intensity in rural areas of the municipalities of the State of São Paulo, Paraná, Mato Grosso do Sul, Mato Grosso and Goias for the years 2000 and 2010. Through factor analysis were generated three indicators (represented by fatorais scores of factors extracted) namely: the indicator of rurality, the agriculturalização (intensity of agricultural activities in rural areas) and of non-agricultural income. Analyzing the spatial distribution of these indicators, represented by fatorais scores of factors extracted, it has been found that the rurally little changed between the years 2000 and 2010. Was also observed an increase in the intensity of agricultural activities in rural areas and non-agricultural income in the municipalities belonging to the states of Mato Grosso do Sul and Mato Grosso among the two years analyzed. Different associations have been found of factorials, agriculturalização and rurality scores income non-agricultural.Leading to the conclusion that there is no single pattern of evolution and association between rurality, agriculturalização and non-agricultural income in the states examined in the years 2000 and 2010. Through the exploratory analysis of spatial data, it was found the presence of clusters High-High and Low-Low spatial-bass on borders and states that the intensity of agricultural activities of the municipality i suffer influence of agricultural activities of neighboring municipalities. From this result, sought to estimate the determinants of the intensity of agricultural activities in rural areas, using the concepts of variables and nature, and employing spatial Econometrics. The results of the estimates indicate the presence of spillover effect, i.e., a high value in the variable intensity of agricultural activities in the neighboring municipalities, increases the value of this variable in the municipality i and that the total value of the agricultural credit variables for costing, value of agricultural production divided by the area explored, exploited area divided by the total area of agricultural establishments, non-agricultural area and distance from the municipality to the State capital have relevance to explain the intensity of agricultural activities in rural areas of the states examined. However, the variables explored area divided by the area of agricultural ...
