A proposta basica deste trabalho e tentar compreender como se da a expansao de fronteiras no estado de Goias verificando as relacoes entre o preco da terra e as variaveis de padrao tecnologico - terras irrigadas, numero de tratores, investimentos, dentre outras. Realizou-se uma analise das correlacoes entre as variaveis preco da terra de pastagem e agricola e as variaveis que compoem o nivel de padrao tecnologico, chegando-se a conclusao de que a variacao nos precos da terra nao esta associada a modificacao da estrutura do nivel de padrao tecnologico em funcao do baixo coeficiente de correlacao encontrado. Isso pode ter ocorrido, talvez, por uma forte especulacao de terras no territorio, pois a antiga regiao de fronteira foi se tornando saturada impedindo novas ocupacoes ou assentamentos. Palavras-chaves: Frente de expansao, frente pioneira, renda diferencial, padrao tecnologico, coeficiente de correlacao. Abstract: The main purpose of this paper is to try to understand as how occurs the borders expansion in the state of Goias showing the relationship between land price and the variables of technological standard, as irrigated lands, tractors number and investments among others. It has been done an analysis of correlations among variables as cattle and agricultural land price and composing variables of the level of technological standard, structure modification of technology standard, as function of low coefficient of found correlation. It could occurred, maybe, by a strong speculation of land prices in this area, as the ancient border region was been saturated obstructing new occupations and settlements.
