摘要：
Super efficiency evaluations are introduced along the lines of the potential improvements approach in Journal of Productivity Analysis 12 (1999) 233. Both a reference selection and a related super efficiency index are defined. The new (potential slack) super efficiency index is compared to a Farrell-based super efficiency index (as in Management Science 39 (1993) 1261) with respect to convex envelopment technologies.
