TYPOLOGY OF MODELS FOR ASSESSING THE TECHNICAL EFFICIENCY OF FOOD POTENTIAL ELEMENTS

The article summarizes the experience of using technical efficiency models based on stochastic frontier production functions, which are an effective tool for studying the technical efficiency of food potential elements. The aim of the work is to identify the distinctive features and analytical capabilities of their types based on the systematization of stochastic frontier production functions. Research objectives: development of a classification system for stochastic frontier production functions; typologization of stochastic frontier production functions; approbation of the application of various types and modifications of functions using empirical data; assessment of the applicability of individual models in the analysis of the technical efficiency of elements of food potential. As a result of the work carried out, the most commonly used models of the stochastic frontier production function were identified, their types were identified within the proposed classification groups. In addition, based on empirical data from grain and leguminous crop producers in the Saratov region for 2010-2022. The main differences and prospects of using individual models in conducting research on the effectiveness of elements of food potential are shown. We have established that the model of time-dependent technical efficiency, taking into account technological changes, providing a similar result in terms of parameters common to all models, has additional capabilities for evaluating the dynamic indicators of the object of study. The results obtained indicate a low rate of technological development of grain production — 1.62% per year, and an increase in the technical efficiency of producers — by 10.46% over the entire period of the study.
