SANTOS, Ricardo Bruno Nascimento dos. Technical efficiency in brazilian forest industry base via milestones. Rev. Árvore [online]. 2011, vol.35, n.6, pp.1319-1326. ISSN 1806-9088. http://dx.doi.org/10.1590/S0100-67622011000700018.
This work aimed to search for targets in stages with intermediate targets in the isoefficiency layers so that the Manufacturing Sector of Forest-Based Products (MSFBP) of each state gradually reached a higher technical level of efficiency. Data from Pesquisa Industrial Anual (PIA) (the Annual Industrial Survey) 2007 from Instituto Brasileiro de Geografia e Estatística - IBGE (Brazilian Institute of Geography and Statistics) were used. Data envelopment analysis (DEA) was applied geared towards inputs. Net revenue in the sector as a product and inputs was the total industrial operations cost (IOC) and wages in the sector (WS). Among fourteen analyzed states, Espírito Santo State is the most efficient and Rio de Janeiro the most inefficient. Another twelve states are technically inefficient, so that three states shall, in the short term, seek the layer 1, three for the layer 2, two for the layer 3, and three for the layer 4. It was found that in Brazil the IOC is the main cause of technical inefficiency.
