本文以实际贸易为出发点,采用2005.1~2010.12的月度数据,对外部冲击对我国物价的传导效应进行实证分析,定量给出外部冲击对输入型通胀的影响和对国内物价的传导路径。研究表明,外部冲击能通过进口价格传导到国内价格体系,但传递不完全,国际大宗商品价格冲击最大。外部冲击对国内物价的传导路径存在中下游价格倒逼上游价格的现象;进口价格对上中下游价格的传导都不显著,其它价格却能反向传导到进口价格。 Based on the actual trade, this paper uses monthly data from January 2005 to December 2010 to analyze empirically the conduction effect of external shock on China’s price, and quantitatively gives the impact of external shock on input inflation and the conduction path to domestic price. Research shows that external shocks can be transmitted to the domestic price system through import prices, but the transmission is incomplete and the impact of international commodity prices is the biggest. The impact of external shocks on the domestic price channel exists in the middle and lower reaches of the price of upstream prices forcing the phenomenon of the import price of the conduction of prices in the middle and lower reaches are not significant, other prices can be reversely transmitted to the import price.
