Summary in the original language of the document
Sabe-se que a agricultura e uma atividade que depende, basicamente, das potencialidades do meio ambiente fisico natural onde ela se desenvolve. No entanto, os processos tecnologicos associados a disponibilidade dos fatores capital e mao-de-obra sao capazes de influenciar fortemente os niveis de produtividade e de producao a serem obtidos em dado meio fisico agroeco1ogico. Dessa forma, o conhecimento da eficiencia no uso dos fatores em zonas agroecologicas, similares quanto a sua estrutura de producao, pode indicar o seu uso mais racional. Pretende-se, neste trabalho, estimar a eficiencia/ ineficiencia tecnica no uso dos fatores de producao em zonas agroecologicas brasileiras. Para tal, especificamente procurou-se: agrupar e caracterizar as zonas agroecológicas brasileiras de acordo com sua estrutura de producao; estimar e comparar os niveis, inter e intragrupais, de eficiencia/ineficiencia tecnica dos fatores de producao. Para alcancar o primeiro objetivo utilizaram-se duas tecnicas de analise mu 1 1 ivariada, a saber: a analise fatorial em componentes principais e a hierárquica aglomerativa. O segundo objetivo foi alcancado mediante a estimativa, inter e intragrupal, do indice geral de eficiencia tecnica, obtida atraves das diferencas encontradas entre os interceptos da funcao de produção fronteira e do calculo do indice parcial da eficiência tecnica, dado pela produtividade media dos fatores de producao. Pode-se concluir, portanto, que a analise permitiu caracterizar as diferentes realidades regionais, tornando possivel identificar regioes diferenciadas quanto a estrutura de producao e quanto aos niveis de eficiência tecnica dos fatores de producao. Essa analise pode ser utilizada como base de conhecimento sistematizado que, em termos de planejamento agricola, atenda as características regionais da estrutura de producao e busque o desenvolvimento de tecnologia apropriada para os diferentes ecossistemas.
Summary translation
It is known that agriculture and an activity that basically depends on the potential of the natural physical environment in which it develops. However , the technological processes associated with the availability of capital and factors mao workforce are able to strongly influence the levels of productivity and production to be obtained in agroeco1ogico given physical environment . Thus , knowledge of the efficiency in the use of agroecological factors in similar areas as the structure of production , may indicate its rational use . It is intended in this work to estimate the efficiency / inefficiency in the use of production factors in Brazilian agro-ecological zones . To this end , specifically sought to : cluster and characterize the Brazilian agro-ecological zones according to their structure of production ; estimate and compare the levels , inter and intragroup of efficiency / inefficiency of production factors . To achieve the first objective were used in two Technical analysis of mu 1 1 ivariada , namely the factor analysis in principal components and hierarchical glomerativa . The second objective was achieved by estimation, inter-and intra-group , the general index of technical efficiency obtained through the differences found between the intercepts of the frontier production function and the calculation of the partial index of technical efficiency, given by the average productivity of production factors . It can be concluded , therefore, that the analysis allowed us to characterize the different regional realities , making it possible to identify different regions as the structure of production and how the levels of technical efficiency of production factors . This analysis can be used as the basis of systematized knowledge that , in terms of agricultural planning , attend the regional characteristics of the structure of production and seek the development of appropriate technology for different ecosystems .
