Abstract

The purpose of this study is to investigate the own price elasticity and cross-price elasticity for energy factor demand, and the cost elasticity for energy prices based on the results estimated the cost function of greenhouse vegetable cultivation farms. This study uses the raw agricultural income data of the Rural Development Administration in 2022. Through these elasticity measurements, the cost structure characteristics of greenhouse vegetable cultivation farming, such as changes in energy factor demand, the possibility of substituting energy with other inputs, and changes in agricultural production costs, were analyzed when energy prices rise. As a result of the analysis, the own price elasticity value for energy factor demand was relatively higher than the own price elasticity of other inputs, confirming that greenhouse vegetable cultivation farming is more sensitive to changes in energy prices than other input prices, and that energy has a cost structure that is difficult to substitute with other inputs. Therefore, when energy prices rise, it is efficient for greenhouse vegetable cultivation farming, which uses relatively high amounts of energy, to use renewable energy that can reduce energy usage costs, and it was found that energy replacement can be achieved more quickly starting with farms with large farm sizes.
