摘要
选取2003年~2013年的月度玉米价格数据,分为2008年以前和2008年以后两个样本区间,采用脉冲效应函数和方差分解的方法,从产业链的视角研究了我国玉米价格的传导机制,其中重点考察了玉米饲用消费产业链和以玉米淀粉为代表的工业深加工消费产业链。研究表明：与2008年以前相比,2008年以来,我国玉米价格在产业链上的价格传导作用明显增强且具有非对称性。
According to price monthly data from 2003 to 2013 which was divided into two sample areas, this paper studied the maize price transmission mechanism from the perspective of industry chain, using the Impulse Response Function and Vari- ance Decomposition methods, especially for the maize feed consumption industry and the maize deep-processing consumption industry which was represented by maize starch. Research has shown that, since 2008, the transmission effects of maize price in the industrial chain have significantly enhanced compared with those before 2008 in China. Meanwhile, from this study, the price transmission of maize price in the industrial chain in China was unsymmetrical between before 2008 and after 2008. And overall, the effects of maize price on the upstream and downstream price transmission were stronger than that of upstream and downstream price transmission on maize price.
