The concentration of ozone, one of major air pollutants, is gradually increasing, enormously damaging not only human body but also animals and plants. In particular, its strong oxidization gives harmful effects on a number of plants. The purpose of this analysis is to find out what impact rice yield changes from the amount of ozone can give to social surplus. For this purpose, dose-response function is used to clarify relations between rice and ozone based on materals generated from the open top chamber system, by putting them into weibull function to estimate. This research covers seven regions in Korea, Gyeonggi-do, Chungcheongbuk-do, Chungcheongnam-do, Jeollabuk-do, Jeollanam-do, Gyeongsangbuk-do and Gyeongsangnam-do, where 91.3% of the entire Korean rice production is made. The rice yeild increased by 1.5%, 2∼3% and 4∼7% respecitvely when ozone polluation reduced by 5%, 10% and 20% compared to that of 2000. From calculating social surplus of Korea by using the optimization model, about 420 billion won, 830 billion won and 1.73 trillion won of social surplus are estimated to be additionally generated in each case when 5%, 10% and 20% of ozone concentration amount decrease in comparison with that of 2000.
