An analysis of the technical efficiency of industrial water Input in manufacturing

Frame of Image paper estimates the technical efficiency of industrial water in order to test whether the reduction of industrial water usage is a result of improving the level of technical efficiency of industrial water. This paper shows that the technical efficiency of industrial water use slightly decreased from 0.5183 in 1998 to 0.4853 in 2003. In addition, these estimates are much less than those of other inputs and so, there is still much room for reducing the amount of industrial water use through improving technical efficiency even though the average productivity of industrial water has improved during this period. ❙Keywords ❙ Technical  Efficiency,  Data  Envelop  Analysis,  Industrial  Water

Ⅰ. Introduction
Until  the  early  1990’s,  the  water  management  policies  of  Korea  focused  on  water  supply.  For  example,  the  government  had  constructed  several  dams  to  meet  the  increasing  demand  for  water.  However,  these  supply‐side  policies  encountered  difficulties  due  to  serious  environmental  damage  during  the  1990’s.  Therefore,  the  government  shifted  the  focus  of  its  water  policies  from  supply  to  water  demand  management  in  order  to  resolve  future  water  shortage  problems. However,  until  the  1990’s  the  water  demand  management  policy  regarding  industrial  water  was  rarely  applied  due  to  a  set  of  limiting  factors.  For  example,  it  is  difficult  to  estimate  the  exact  amount

Abstract

While water management policies in Korea have focused on industrial water demand during the last decade, the amount of industrial water usage has decreased significantly. This paper estimates the technical efficiency of industrial water in order to test whether the reduction of industrial water usage is a result of improving the level of technical efficiency of industrial water. This paper shows that the technical efficiency of industrial water use slightly decreased from 0.5183 in 1998 to 0.4853 in 2003. In addition, these estimates are much less than those of other inputs and so, there is still much room for reducing the amount of industrial water use through improving technical efficiency even though the average productivity of industrial water has improved during this period.
