Resumo: | The theme about efficiency and productivity of companies that act in regulated industries have been extensively discussed in literature. In Brazil, there are just a few studies about the analysis of efficiency and productivity of interstate passenger coach transportation (trip). in this sense, this paper has three main objectives: to choose between the Cobb-Douglas and translog functions which is the best function to measure the technical efficiency on trip for the period of 2004-2006; to compare the efficiency scores among the companies of trip; and to make an analysis of the efficiency dynamic on trip and the factors that contributed for the gains and losses of the efficiency. It can be a strategy to competition in a long term. The results indicate a loss of efficiency during the years analyzed and this loss is probably due to the expansion of the capacity installed by acquisition of new buses, it can be a strategy to compete in quantity. The increase in production in 2005 based on 2004 is 4%; however, it was accompanied by an increase of 6% and 26% of annual distance traveled in km and employment of labor (drivers,) respectively, and 31% reduction in fleet use, with similar results for 2006. |

The theme about efficiency and productivity of companies that act in regulated industries have been extensively discussed in literature. In Brazil, there are just a few studies about the analysis of efficiency and productivity of interstate passenger coach transportation (trip). in this sense, this paper has three main objectives: to choose between the Cobb-Douglas and translog functions which is the best function to measure the technical efficiency on trip for the period of 2004-2006; to compare the efficiency scores among the companies of trip; and to make an analysis of the efficiency dynamic on trip and the factors that contributed for the gains and losses of the efficiency. It can be a strategy to competition in a long term. The results indicate a loss of efficiency during the years analyzed and this loss is probably due to the expansion of the capacity installed by acquisition of new buses, it can be a strategy to compete in quantity. The increase in production in 2005 based on 2004 is 4%; however, it was accompanied by an increase of 6% and 26% of annual distance traveled in km and employment of labor (drivers,) respectively, and 31% reduction in fleet use, with similar results for 2006. |
