Efficiency evaluation of regional ecological economic systems based on the network DEA model

Abstract

It is the usual policy of Inderscience to retract from publication any paper if, subsequent to publication, it becomes a matter of dispute about intellectual property, publishing ethics or legal issues. Each case is judged on individual circumstances. In this case, the authors ask that this paper be removed from the journal because following publication the authors found some calculation errors in the paper which needed attention. This paper has therefore been retracted.
