Abstract
The authors propose a method of assessment of efficiency of regional
PES’s by selecting statistically significant inputs and outputs as well as the
environmental variable. In the final DEA model variables which show the
positive correlation and statistically significant relationships between input
variables and outputs (effects) were selected. Among the environmental
variables the one with the strongest relationships with output variables
was chosen. For the purposes of the resource management assessment of
PES’s an analysis of technical relative efficiency of two Polish provinces was
conducted using the Data Envelopment Analysis (DEA) method. These
provinces represent a different labour market situation as Podlaskie is one of
the peripheral regions and Mazowieckie voivodeship has the best economic
indicators in Poland. The analysis has shown that the environmental variable
has a significant impact on PES performance (overall improvement in technical
efficiency results). The results of the analysis also enabled the identification
of benchmark PES’s, the identification of areas requiring improvement and
the selection of changes that will contribute to improving efficiency more
prominently than for other variables.
