(An Analysis of Effects of the Changes in Oil Price on Income Ratio of Greenhouse Farming)

The purpose of this study is to take a close look at what crops sensitively react to the change in oil prices by analyzing the relation between oil prices and income ratio of greenhouse farming. In addition, this study also analyzed how differently the adjustment takes place in different regions for the same greenhouse crops. The analysis shows that the crops and the regions reacting sensitively to the changes in oil prices are generally those whose shares of energy cost in total production cost are relatively high. The income ratios for tomatoes, cucumber, and rose are expected to be most significantly affected by the rise in oil price. It is also shown that the income ratio considerably drops when oil price rises up to 1,200 won per liter. The result indicates that greenhouse farming might confront with serious difficulties without appropriate policy tools to help reduce the burden of the increased cost.
