359generally, it is possible to state that the objective of the rational owner, respectively management is the profit maximization with minimal inputs applying, that means costs. This objective can be defined as an optimizing task the solution of which could be achieved by applying the linear programming methods, that means the non-parametric approach or by econometric methodology -parametric approach. common sign for both mentioned approaches is production frontier quantification. While parametric approach assume that we know explicit estimation of production function but we do not know its parameters, results of non-parametric approach are estimated measures of technical efficiency which reflect on the company's position either on the production frontier in case of an effective company, or under the frontier in case of an inefficient company.We focused our research on the non-parametric approach application to estimate the companies' efficiency which is known as the Data Envelopment Analysis (DEA). The DEA reaches good results on small extents of the analysed companies and in caseThe returns to scale analysis in the basic industry enterprises in the Slovak Republic

Department of Economics, Faculty of Economics and Management, Slovak University of Agriculture in Nitra, Nitra, SlovakiaAbstract: The analysis in field of the returns of scale is an important indicator which denotes if it is effective for the analyzed companies to increase the input exploitation to expand the production program with the aim to reach higher profits than invested inputs. According to this reason, the objective of the research is the analysis of return to scale in the basic industry enterprises in the Slovak republic. During the whole analysed period, there was estimated the most numerous group of companies which occurred in the area of decreasing returns to scale. This fact confirmed that the total input exploitation in agricultural companies is in a higher measure not profitable, because in comparison with production inputs, lower profits were reached. on the basis of these results, it is not possible to exactly estimate which inputs are indispensable to optimize (for a more specific estimation, it is necessary to apply the non-radial DEA methods), despite the fact that there was evidently confirmed the low measure of input profitability.Key words: Data Envelopment Analysis (DEA), returns to scale, agricultural enterprises, basic industry Abstrakt: Analýza oblasti výnosov z rozsahu je dôležitým ukazovateľom, ktorý vypovedá o tom, či je pre súbor analyzovaných podnikov výhodné rozširovať využívanie vstupov na rozšírenie výrobného programu s cieľom dosiahnuť vyššie výnosy ako vložené vstupy. z uvedeného dôvodu bola cieľom príspevku analýza výnosov z rozsahu v podnikoch poľnohospodárskej prvovýroby v Sr. Počas celého skúmaného obdobia bola odhadnutá najpočetnejšia skupina podnikov, ktor...
