摘要:GESis (Neves 2008) is a practical process for developing strategic plans for production chains and was applied to several projects in Brazil. One of the initial steps is mapping and quantification of production chains. This step provides knowledge of the size of the chain analyzed, in terms of social and economic magnitude. Using the method GESis, the main objective of this article was to estimate the financial transactions for one of the most important production chains to Brazil, the beef chain. In this research, the gross value of the beef sector in Brazil was estimated at $167.5 billion in 2010. This material can serve as a stimulus to public and private decision-making and it shows the intimate interconnection between the links in the chain and its ability to generate revenues, taxes and jobs.
