Abstract
Nonparametric efficiency analysis methods such as data envelopment analysis (DEA) have been widely employed for evaluating eco-efficiency. However, virtually all published studies in this literature implicitly assume weak sustainability. This is a very strong assumption that allows for substitution among different forms of inputs and/or outputs, treating ecological conservation as merely one among several competing objectives that can be traded off against economic growth. To broaden the scope of nonparametric eco-efficiency evaluation, this paper proposes a novel approach based on a strong sustainability perspective. Drawing on a newly introduced method termed Fixed Proportion Constrained DEA, our eco-efficiency evaluation approach restricts the substitutability among inputs and/or transformability among outputs, highlighting the intrinsic value and irreplaceability of ecosystem services and natural capital. By incorporating this perspective into eco-efficiency measurement, our proposed method offers a more comprehensive understanding of sustainability and underscores the importance of preserving natural ecosystems for future generations.
