本文基于2010年2月至2015年4月的小麦月度价格指数数据，采用非对称误差修正模型，对国际小麦价格非对称性传导效应在贸易路径和期货路径两方面分别进行了检验。结果表明，国际小麦现货价格和国际小麦期货价格与国内小麦收购价格之间存在长期均衡关系，但是无论是基于贸易路径还是期货路径，国际价格对国内价格传导都表现出对称性，这一点与假设不符，为此本文在结尾给出了解释。%Based on monthly wheat price index data of 2010 February to 2015 April, using asymmetric er-ror correction model study on trade test path and futures path international wheat prices conduction char -acteristics .The results showed that there is the long -term equilibrium relationship between the interna-tional wheat spot price and futures prices of international and domestic wheat price , but whether it is fu-tures or trading route path based on international prices for domestic prices showed symmetry , which is not match the hypothesis , so that an explanation will be given at the end of this article .
