This paper aims at analysing the technical efficiency and productivity of the 22 railroad lines using the SBM model and the Malmquist index. This paper utilizes data for the period 2004-2010. The SBM model uses two inputs to produce two outputs. The inputs consist of the number of staffs and non-labor cost and the outputs are the passenger revenue and man-kilometer. The result shows that most of lines not only have larger operational inefficiencies than scale ones, but are in a condition of increasing returns to scale. That indicates that it is more reasonable to increase the staffs as well as the investment in infrastructure rather than downsize the organization. The SBM/WINDOW analysis reveals that there is a very large efficiency gap among the DMUs. The efficiency is only greater than 0.8 in 3 of 22 lines, but that of 14 lines is below 0.4. The Malmquist productivity analysis indicates that both technological progression and higher technical efficiency enable the 9 lines including Kyungbu High Speed Line to increase their productivity. The other lines, however, suffer from lower productivity due to decrease of technical efficiency in spite of technological progression. The Kyungbu High Speed Line is shown to record the highest productivity increase of all lines.
