An Empirical Study on the Efficiency Analysis of Management Using the Meta-frontier Method

This study evaluates efficiency from the viewpoint of the short-term and long-term of general construction companies. In general, people think that the higher the rating, the higher the efficiency. The data envelopment analysis (DEA) was used to analyze the significance of these hypotheses, and the meta-frontier was used to evaluate the hypotheses. Data envelopment analysis (DEA) is non-parametric analysis method which is commonly used in efficiency analysis. DEA is a methodology for identifying the relative efficiency of DMUs. It is introduced by Charnes, Cooper and Rhodes (CCR). As a result of the analysis, the overall construction industry showed very high operating efficiency, and most of the inefficiency of the technical efficiency is the result of low scale efficiency. Only 2 out of 2,595 firms with an increase in size (IRS) in economies of scale were found to have 47, and the rest were downsized. The same results were obtained when applied to individual groups. The lower the rating, the lower the efficiency, which is also the cause of economies of scale. And there is no difference in efficiency between regions.
