Resumo
O artigo foca o setor brasileiro de operadores logísticos (OLs) que, frente a um cenário altamente competitivo, oferece a seus clientes uma gama de serviços e de tecnologias de informação em busca de níveis maiores de eficiência. Seu objetivo principal é determinar as variáveis que apresentam impacto significativo na eficiência de escala dos OLs, por meio de modelagem de DEA (Data Envelopment Analysis – análise envoltória de dados) em dois estágios. Dados (2001-2008) da pesquisa anual feita pela Revista Tecnologística foram utilizados em um modelo de painel incompleto. Os inputs e outputs necessários para essa análise foram identificados, assim como as variáveis contextuais que podem impactar na eficiência de escala dos OLs. Os resultados corroboram evidências na literatura sobre o papel dos processos de coordenação no desempenho logístico.
Palavras-chave

Abstract
This paper focuses on the third-party logistics (3PL) industry in Brazil which, facing a highly competitive scenario, offers its clients a broad range of services and information technologies in pursuit of higher levels of efficiency. Its main objective is to determine the variables that significantly impact on the 3PL scale efficiency by means of a two-stage Data Envelopment Analysis (DEA). Data (2001-2008) from the annual survey developed by Revista Tecnologística were used in an unbalanced panel data model. The inputs and outputs required for this analysis were identified as well as the contextual variables that may impact on the 3PL scale efficiency. The results corroborate the evidence in the literature on the role of coordination processes in the logistics performance.
