This study targeted two purposes. Firstly, we examined the effect of climate changes on crop changes such as Chinese cabbages and Korean radishes, which are typically grown in unprotected farm fields. Through this examination, we intended to estimate cabbage and Korean radish yield models reflecting relevant weather factors and examine the effect on cabbage and Korean radish yields. Secondly, we aimed to assess the time series model of cabbages and Korean radishes, reflecting seasonal features to examine characteristics of price changes and find out which climate changes occur when prices significantly change. The result of this study will contribute to examining what climate changes occur in the season and when the price of Chinese cabbages and Korean radishes dramatically changes. We believe that our accomplishment will help the government establish preemptive strategies for stabilized supply and demand of Chinese cabbages and Korean radishes.
