Industrial complexes have shown significant roles in advancing Korean manufacturing. Especially the national industrial complexes are regarded as driving forces of Korean economy. At this juncture, it is meaningful to measure the efficiency of the national industrial complexes and evaluate what areas should be considered to improve the efficiency of the complexes. This study uses the DEA models to measure the efficiency of the national industrial complexes. Malmquist Productivity Index is also used to evaluate the productivity changes of the complexes for last 10 years. Malmquist Productivity Index shows the change of efficiency for a certain period in terms of the change of technical efficiency and technical change. The study provides the effects of the changes of technical efficiency and productivity of the national industrial complexes and suggests policy implications.
