Resumo: The article identifies the spatial concentration of production and analyzes the sources of growth and income instability of the corn crop in the state of Pará. Time series of harvested area, production, productivity, gross production value and corn prices in the state of Brazil were used. Pará, from 1990 to 2018, obtained from the Brazilian Institute of Geography and Statistics (IBGE). To assess the level of spatial concentration, the Locational Quotient and the Gini Index were determined. The assessment of the sources of growth was carried out based on the Shift-Share model, which allows decomposing the variation in the gross value of production in the effects of harvested area, yield and price. Income instability was estimated by determining the Cuddy Della Valle Index. The results indicate that fluctuations in the gross value of production in the early 1990s were associated with the expansion of cultivated areas, in contrast to the current scenario where fluctuations are greatly influenced by increased productivity. The most specialized microregions in corn production are: Paragominas, Conceição do Araguaia, Parauapebas and Santarém. The concentration of production is relatively high and the income generated by the crop shows low instability as it is strongly associated with price stability in recent years.

Se utilizaron series temporales de área cosechada, producción, productividad, valor bruto de producción y precios del maíz en el estado de Brasil. Pará, de 1990 a 2018, obtenido del Instituto Brasileño de Geografía y Estadística (IBGE). Para evaluar el nivel de concentración espacial, se determinaron el cociente de ubicación y el índice de Gini. La evaluación de las fuentes de crecimiento se realizó en base al modelo Shift-Share, que permite descomponer la variación en el valor bruto de la producción en los efectos del área cosechada, el rendimiento y el precio. La inestabilidad de los ingresos se estimó determinando el índice de Cuddy Della Valle. Los resultados indican que las fluctuaciones en el valor bruto de la producción a principios de la década de 1990 se asociaron con la expansión de las áreas cultivadas, en contraste con el escenario actual donde las fluctuaciones están muy influenciadas por el aumento de la productividad. Las microrregiones más especializadas en la producción de maíz son: Paragominas, Conceição do Araguaia, Parauapebas y Santarém. La concentración de la producción es relativamente alta y el ingreso generado por el cultivo muestra una baja inestabilidad, ya que está fuertemente asociado con la estabilidad de precios en los últimos años.Objetivou-se com o estudo identificar a concentração espacial da produção e analisar as fontes de crescimento e instabilidade da renda da cultura do milho no estado do Pará. Foram utilizadas séries temporais de área colhida, produção, produtividade, valor bruto da produção e preços do milho no estado do Pará, no período de 1990 a 2018, obtidas a partir do Instituto Brasileiro de Geografia e Estatística (IBGE). Para avaliar o nível de concentração espacial, foram determinados o Quociente Locacional e o Índice de Gini. A avaliação das fontes de crescimento foi efetuada com base no modelo Shift-Share que permite decompor a variação no valor bruto da produção nos efeitos área colhida, rendimento e preço. A instabilidade da renda foi estimada por meio da determinação do Índice de Cuddy Della Valle. Os resultados indicam que as flutuações no valor bruto da produção no início da década de 1990 estiveram associadas a expansão das áreas de cultivo, contrastando com o cenário atual onde as flutuações sofrem grande influência da produtividade. As microrregiões mais especializadas na produção de milho são: Paragominas, Conceição do Araguaia, Parauapebas e Santarém. A concentração da produção é relativamente alta e a renda gerada pela cultura apresenta baixa instabilidade por ser fortemente associada à estabilidade dos preços nos últimos anos.Research, Society and Development2020-07-30info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://rsdjournal.org/index.php/rsd/article/view/573310.33448/rsd-v9i8.5733Research, Society and Development; Vol. 9 No. 8; e566985733Research, Society and Development; Vol. 9 Núm. 8; e566985733Research, Society and Development; v. 9 n. 8; e5669857332525-3409reponame:Research, Society and Developmentinstname:Universidade Federal de Itajubá (UNIFEI)instacron:UNIFEIporhttps://rsdjournal.org/index.php/rsd/article/view/5733/5164Copyright (c) 2020 Carina Chagas Madeira de Souza, Joyce dos Santos Saraiva, Marcos Antônio Souza dos Santos, Fabrício Khoury Rebellohttp://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessSouza, Carina Chagas Madeira deSaraiva, Joyce dos SantosSantos, Marcos Antônio Souza dosRebello, Fabrício Khoury2020-08-20T18:00:17Zoai:ojs.pkp.sfu.ca:article/5733Revistahttps://rsdjournal.org/index.php/rsd/indexPUBhttps://rsdjournal.org/index.php/rsd/oairsd.articles@gmail.com2525-34092525-3409opendoar:2024-01-17T09:29:09.469128Research, Society and Development - Universidade Federal de Itajubá (UNIFEI)false
