【 摘 要 】

Improving agricultural productivity has been an important area of research to assure that the needs of a growing population do not outstrip the ability for producers to supply food.This growth in demand will mostly come from developing countries.The tension between producing more food and reducing the impact on the world’s natural resources reflects a significant challenge for global agribusiness in general, and specifically in the new agricultural growth regions in the tropics.Therefore the primary objective of this research is to better understand and examine the production economics of the tropical soybean-maize succession cropping, which have not received much attention by researchers, and thus are not well understood.This paper measures changes in agricultural total factor productivity (TFP) from the succession cropping system of soybean and maize in Mato Grosso, Brazil from 2005 to 2012 using farm level data.The second objective of this research is to analyze the input and output factors driving total factor productivity.Total factor productivity takes into consideration all of agricultural inputs (land, labor, fertilizer, seed, pesticide, diesel, and machinery) used in the production of soybean and second maize (safrinha) crops and compares them with the total amount of agricultural output.A Tornqvist index is created to minimize biases that may result from relative price changes in input and output cost shares.The results indicate that the agricultural TFP of the soybean-maize succession cropping system increased 6% from 2007-2012.
