기후변화 대응 식량안보를 위한 지불의사 분석

Abstract

This study examines consumers' perception of and willingness to pay for food security under climate change in Korea. We surveyed 508 consumers and found that 91.9% of those questioned perceive that climate change is a serious problem and 80.4% reply that climate change would have a negative effect on food security. All five components of food security index designed by Yang and Kim (2011) were perceived as important factors and the self sufficiency ratio is regarded as the most important component followed by the international market situation. Some 52% of conusmers perceive that the 32% target self-sufficiency ratio of grain set by the government is not sufficient for food security. The optimal target ratio suggested by the respondents is 48.9%. We also surveyed the willingness-to-pay (WTP) for food security using a multi-alternative question method with the indirect tax either on oil or food as a means of payment. The results show that the consumers who prefer taxing on oil to food would pay 1.66% more in addition to the current value-added tax, while those who prefer taxing on food to oil would pay 1.79% more. The total amounts of WTP calculated are 902 billion Korean won (US $801 million) for oil tax and 1,375 billion Korean won (US $1,221 million) for food consumptio ntax, respectively.
