Opis:
The paper presents the literature review concerning the general assumptions of the Data Envelopment Analysis (DEA) and its applications in forest management and wood industry evaluation. So far, efficiency evaluation in forestry sector was carried out using mostly the ratio analysis only. The DEA approach, which was developed in the 1970s, is based on the mathematical programming algorithm and gives more opportunities to analyze efficiency in forestry sector. We describe the main steps of DEA and possible options for the analysis. It also discusses the advantages and disadvantages of the method applications. We also present the most significant papers concerning DEA application in forest management and wood−based industry. As far as forest management is regarded, DEA was used for evaluating forest offices, administration and institutions and optimizing forestry operations performed by both private and state−owned companies. In case of wood−based industry, the method was used mostly for evaluating efficiency of sawmills and pulp mills. Most of the research in this field was carried out in the United States and Canada. DEA was applied to measure efficiency in forest management in Poland only recently, which should be considered as a good step towards improvement of research quality in this field in Poland and should provide comprehensive results of forest management efficiency evaluation. The method should be used more widely to evaluate efficiency of various aspects of forestry and wood−based industry in Poland.

Opis:
The aim of this paper was to evaluate the financial and economic resources efficiency of forest districts in the years 2008−2012 using a nonparametric approach of the Data Envelopment Analysis (DEA). DEA is a linear programming based method for evaluating the performance of comparable production units such as firms. The relative efficiency of compared forest districts is calculated with the Variable Returns to Scale (VRS) model. Although the method is already extensively applied in many areas of economics, its use in forestry remains limited. We studied 110 forest districts from Wrocław, Katowice, Kraków and Krosno regional directorates of the State Forests. The research was conducted in groups of forest districts according to the similar forest site type, which ensured the homogeneity of the units and the comparability of research results. Two categories of the forest districts were identified: ‘lowland' and ‘upland−mountain' ones. The study covered selection of input (efforts) and output (results) variables as well as selection of appropriate DEA model, which were used to evaluate technical efficiency of the forest districts. Within the so−called model of economic resources they were quantified in technical units, whereas in a financial model – in value terms. The research shows differences in the use of economic and financial resources by the analyzed forest districts. The ‘lowland' were more effective than ‘upland−mountain' ones both in terms of the use of the financial and economic resources. Average relative efficiency in a financial model for the ‘lowland' forest districts amounts to 0.896, while for the ‘upland−mountain' ones – to 0.839. In economic resources model this parameter equals 0.853 and 0.823, respectively. The DEA method may be an alternative or complementary to other methods of evaluation of the forest district efficiency. Any attempt of such analysis may be very valuable support in the forest management.
