摘　　要：近二十年来中国大豆进口规模急剧扩张。本文基于价格楔方法扩展模型,通过引入消费偏好和替代弹性,放宽以往研究对于国产大豆和进口大豆的同质假设,进一步利用2012—2018年中国与美国、巴西的大豆贸易月度数据,测算了中国对从两国进口大豆所实施的非关税措施的关税等值水平。测算结果表明,2012—2018年间,中国对美国来源和巴西来源大豆实施的非关税措施的关税等值分别为14%-83%和10%-181%,均远高于3%的大豆进口关税。研究还发现,与国产大豆相比,国内消费者更偏好于进口大豆特别是巴西大豆;国产大豆与进口大豆的替代弹性大于1,大量进口大豆会对国内大豆生产造成冲击。China’s soybean import scale has expanded dramatically in the past two decades.Based on the price wedge method,this paper introduces consumption preferences and substitution elasticity,and expands the homogeneity assumptions of domestic and imported soybeans in previous studies.It applies the monthly data of China’s soybean trade with the United States and Brazil from 2012 to 2018 and calculates China’s Tariff equivalent levels of non-tariff measures implemented on soybean imports from both countries.Calculation results show that from 2012 to 2018,China’s tariff equivalents to non-tariff measures implemented by the United States and Brazil are 14%-83%and 10%-181%respectively,which are much higher than the 3%soybean import tariff.The study also finds that compared with domestic soybeans,domestic consumers prefer imported soybeans,especially Brazilian soybeans.The substitution elasticity of domestic soybeans and imported soybeans is greater than 1,and a large proportion of soybean imports will impact domestic soybean production.
