文章对CPI“篮子商品”中非食品类和食品类商品的价格传导机制进行考察,采用2005—2010年月度价格指数数据实证分析了两个产业链渠道的上中下游价格传导效应。研究结果显示,两个渠道内的价格指数之间都存在稳定的长期均衡关系,但短期内食品渠道内的价格传导比非食品渠道顺畅,而非食品渠道内存在显著的价格倒逼机制。当两个产业链上的价格各自受到外部冲击时,在食品渠道中能显著传递至下游的CPI,但在非食品渠道中传递至CPI的效应并不明显。

This paper investigates the price transmission mechanisms of nonfood and food products in the basket of products concerning CPI and empirically analyzes the upstream, midstream and downstream price transmission effects of nonfood and food industrial chains by using the data of monthly price index from 2005 to 2010. Empirical results show that there exists stable long-run equilibrium relationship among price indexes in both two channels. But in the short term, the price transmission mechanism in food channel is smoother than the one in nonfood channel, while there is an obvious reversed price mechanism in nonfood channel. When the upstream prices suffer an unexpected shock in both industrial chains, the impact will be transmitted to the downstream prices significantly in food channel while the pass-through effect is not significant in nonfood channel.
