ABSTRACT
This paper discussed the circumstances that do not affect the efficiency value of each Decision Making Unit (DMU), and the relation between "evaluating efficiency space" under equivalent Data Envelopment Analysis (DEA). If the changing relation of "evaluating efficiency space" can be controlled, then the changing quantity of each input and output can be controlled. This paper used a substitutive function to identify the substituting relations between inputs or outputs of each DMU. Therefore, by considering the whole market economically, a "lower cost" item can be substituted for a "higher cost" item. To describe this strict deduction, this paper developed 3 theorems, 4 corollaries, and 4 definitions. A few examples were utilized to demonstrate concept practicability.
