Abstract [en]

In this research, data envelopment analysis (DEA) is employed to study the comparative performance of German and Colombian manufacturing industries between 1998 and 2005. The results of the DEA indicate that the great majority of manufacturing industrial sectors improved on this index during the sample period, demonstrating that energy input is an important variable within the production structure and a key element in technology development. At a second stage, regression analysis using panel data analysis reveals that several factors, including labour productive, enterprise size, investments and capital input can be considered determinants of differences in energy efficiency among German and Colombian manufacturing industries. Our results also show that different energy policies should apply across manufacturing industries and that they should encourage the importance of energy efficiency in order to improve it, especially in non-energy-intensive sectors, small and medium enterprises and manufacturing industries of developing countries.
