This paper estimated the demand function of the cuts of pork by using the consumer panel and the weather data from the Korea Meteorological Administration with a log-log model and AIDS model. The results show that the price elasticityof demand for cuts of pork is high in the sequence of arm shoulder, leg, special cuts, tenderloin, blade shoulder. Incontrast, spare rib, belly and loin are classified as low price elasticity of demand. The income elasticities of demandfor leg and blade shoulder are 11% and 7.6% respectively. The loin is classified as inferior goods, because demand decreases when income increases. The results also demonstrate show that the demand increases highly in the sequenceof loin, arm shoulder, spare rib, belly if housewife is older, and the demand of belly increases when family numberincreases. Belly substitutes every cut except spare rib, and tenderloin substitutes special cuts. Spare rib, on the otherhand, does not substitute other cuts. In addition, job status, family member, husband job, purchasing place, consumer characteristic, eating-out times, purchasing time, and weather are statistically significant.
