Analysis of the efficiency of national civil construction firms
The article analyzes the efficiency of national civil construction firms, through the application of Data Envelopment Analysis in multistage, for a pool of construction companies, between the years 2005 and 2008.TheMalmquist index is used to calculate the variation in total factor productivity over the period, decomposing it into variations in technical and scale efficiency and technological progress. The results for our sample, point to significant differences in technical and scale efficiency according to the invoicing level and indicate that, on average, technical efficiency scores decreased between 2005 and 2008, as well as the variation in total productivity of factors. The average technical efficiency score for the period was 0.433 and showed a downward trend since 2006. The total factor productivity in the period from 2005-2008, decreased by 7.2% due, mainly, to the negative variation in the technological progress.
