本文利用投入产出价格模型,以1992～2007年18部门全国可比价投入产出表为基础,测算了我国农产品价格上涨对其他部门的波及效应。结果显示:相同农产品价格上涨幅度对其他部门产品价格的影响呈现逐渐减小的趋势,但在不同部门之间存在一定的差异;另外,相同农产品价格上涨幅度对物价总水平的贡献逐年下降,但近几年农产品价格的大幅度上涨,使得其对物价总水平的贡献度增大。
In this paper, we use the input-output price model to estimate the spillover effect of the rising prices of agricultural products on other sectors based on the input-output tables of the 18 national sectors in 1992-2007. The results show that the influence of the same agricultural product price increase on the product prices of other departments shows a decreasing trend, but there are some differences among different departments. In addition, the contribution of the same agricultural product price increase to the general price level declines year by year. In recent years, the sharp rise in the prices of agricultural products has contributed to its contribution to the general price level.
