Abstrakty

Eko-wydajność może być scharakteryzowany następująco: dobra i usługi mogą zostać wyprodukowane przy użyciu mniejszej ilości energii, zasobów i mniejszej emisji odpadków. Należy pozwolić, żeby możliwości produkcyjne gospodarki były determinowane przez modele typu wejście-wyjście, poszerzone o nakłady pierwotne, generację zanieczyszczeń i spadek zanieczyszczenia. Stopień w jakim wektor produkcji netto może być poszerzony dla danych nakładów pierwotnych i standardów środowiskowych, może być uznany za miarę braku eko-wydajności. Można to również osiągnąć przez obniżenie nakładów pierwotnych dla danych standardów środowiskowych i żądań ostatecznych. (AT)

Eco-efficiency can be characterised as follows: goods and services can be produced with less energy and resources and less waste emission. Let the production possibility frontier of an economy be determined by the input-output model extended by primary inputs, pollution generation and abatement. The degree by which a net-output vector could be extended for given primary inputs and environmental standards can be considered as a measure of eco-inefficiency. This could equivalently be achieved by a reduction of primary inputs for given environmental standards and given final demand. In the first part of the paper radial and slack based measures of eco-efficiency are derived. In the second part the authors propose another approach based on the construction of a production possibility frontier. For this purpose a multi-objective optimization problem with maximisation of final demand for each commodity subject to constraints on the primary inputs is formulated. Then, using data envelopment analysis with the production possibility frontier as the standard envelope, the eco-efficiency of an economy is estimated. The eco-efficiency values for the radial efficiency measure and the one based on the DEA model coincide. A demonstration of the viability of these methods and their relationships is given using input-output from Austria and NAMEA data.
