On the Assessment of Anhui Forestry Input-output Ratio Based on the Super-ratio Model DEA
In order to promote the construction of ecological forestry,Anhui Province has sharply increased its input on forestry from the year 1998.This article has assessed and analyzed its forestry input-output ratio with the assessment model DEA.The result suggests that the ratio is generally high from the year 1998 to 2002,but from the year 2003,the number of invalid years in the view of DEA has obviously increased,most of which the scale outputs are decreasing by degrees.In the background of the practical forestry development,it can be found that the reasons for such a low ratio are the unsteady input,the improper input output-structure and the sufficient technological input.
