The purpose of this study is to analyse the impact on the production constraints of Korean regions through employing the indexes of environmental efficiency and output loss in case of emission constraint on the GHGs. To estimate the indexes of 120 regions in 2006, this study employes technical efficiency based on Hyperbolic Measure of Productive Efficiency. The results reveal that most of the Korean regions undergo the production possibility area to get constricted due to the constraint. Of 120 regions, 34 are environmentally efficient, while 86 have the index less than '1', which means that they have output losses, experiencing the production techniques shift because of the constraint. Environmental efficiencies of Gun regions are slightly higher than those of Si's, while output loss rates of Guns are slightly lower than those of Si's. The correlations of the two technical efficiencies and environmental efficiency of with population size, industry structure and land use as follows. All variables indicate positive correlations with the two technical efficiencies significantly, while the correlations of only industry area ratio and energy intensive industry employees with environmental efficiency have positive correlations significantly. From these results, to reinforce environmental efficiency, it is necessary for the structures of industries and spaces in the regions to be changed into energy saving ones.
