An Analysis on Technical Efficiency of Mango Farms

This study aimed to analyze the manage achievement and technical efficiency of mango farms. The Budget method for each crop, Data Envelopment Analysis (DEA), and bootstrap DEA are used for the analysis. In the case of efficiency is calculated through input-oriented CCR and BCC models. The data used for the analysis are results of an income survey conducted by visiting 19 mango farms. The main results are as follows. First, the total income is 30,885 thousand won, the management cost is 17,597 thousand won, and the income is 12,928 thousand won per unit (10a) of mango farms. Second, the average technical efficiency (TECRS) is 0.686. This means that 31.4% of the input factors are used inefficiently. Third, the average pure technology efficiency (PTEVRS) is 0.899, and the scale efficiency (SE) is 0.762. This means that 10.1% of the inefficiencies are caused by technology and 23.8% by scale. Forth, as a result of bootstrap DEA, the average bias of the CCR model is 0.185 and the BCC model is relatively low, 0.087. Fifth, most of the inefficient farms are producing in the area of increasing return to scale that can be expected to increase efficiency through scale expansion. Sixth, as a result of examining the scale and rate at which resources can be saved by benchmarking the reference group, the cost of establishing an orchard showed the highest saving rate with an average of 45.7%. On the other hand, the material cost, which has the lowest possible reduction ratio, is the largest, with an average of 15,229 thousand won.
