In theory, market orientation and agricultural reforms in Ukraine should have led to increase in agricultural efficiency and productivity, and, as a result, to increase in production volumes. However, volumes of agricultural production decreased gradually. Therefore, the market mechanism did not produce the expected results, and that's why there is a question whether the transfer to private property was the result of the market mechanism, which facilitated the exit of inefficient enterprises from the market and development of more efficient agents, or this transition was simply the result of several decrees regarding the need to transfer from state to private property. In order to analyze real changes in the efficiency of Ukrainian agricultural enterprises, it is important to determine the adequacy of existing methods for the assessment of efficiency. In this paper we propose nonparametric approaches to the assessment of efficiency, and we also analyzed the efficiency of agricultural enterprises, located in a certain Ukrainian region; we determined, which factors have a dominating influence on agricultural efficiency and which resources are used in a least efficient way and why.
