Technical efficiency of potato production in Turkey by Stochastic Frontier Analysis

摘要

This study aims to determine the technical efficiency of potato production enterprises and develop proposals to increase their efficiency by determining the factors that cause inefficiency. Afyonkarahisar province, one of the significant potato production centres in Turkey, was opted for this examination. The data constitute from the statistics obtained from 79 enterprises selected through the stratified random sampling method. "Stochastic Frontier Analysis" (SFA) techniques were utilised to estimate farm-level efficiency values, and the factors affecting the efficiency of potato production were determined by "A Model for Technical Inefficiency" methods. The variables used in the analysis of efficiency models are potato yield, labour, machine operating time, electricity, pure nitrogen, pure phosphorus, and seed usage levels. According to the research findings, it was determined that the technical efficiency scores calculated with the SSA method ranged between 0.244 and 0.999, and the average technical efficiency score was 0.690. It was found that potato enterprises can increase the amount of output by 31.00 without changing the existing inputs. The potato area and plot numbers that cause inefficiency were found statistically significant. For enterprises to increase their efficiency score, expanding their land and reducing the number of plots was proposed.
