DEA 文章英文翻譯

First,the use of ratios leads to a loss of information about the size of

the unit, and implicitly assumes constant returns to scale in

the operation of the units under analysis.

Second, in practice,

many applications do not use identical denominators for all

ratios. They create a variety of performance indicators, based

on different denominators that have the virtue of being

independent of the size of the unit and, therefore, facilitate the

comparison between the units.

Third, although offending

some purists, the ratio approach will not lead to major

difficulties in practice, providing that the role of the DEA

weights is kept under close scrutiny. They should continue to

represent the value of a unit increase in one ratio relative to a

unit increase in another.

Finally, if the ratio form of DEA is

used, it will then be essential that the BCC (Banker et al.,

1984) form of the DEA model be specified. This specification

ensures that all comparisons between units are solely by

interpolation, and that the extrapolation of behavior to

infeasible performance is ruled out.
