本文运用投入产出模型,研究存在生产时滞价格黏性时部门间的价格传导规律。引入价格反应期作为价格黏性的度量指标和部门分类基础,建立价格反应期特征矩阵。运用迭代法,以投入端价格的变化率和价格反应期特征矩阵为依据,计算目标期被波及部门的价格变化率。模型的主要功能:各部门当期的价格变化率;直接消耗系数的变动;投入端的价格变化率。模型运行结果:各反应期的横截面价格变化率;分部门价格变化率时间序列。
Based on input - output model, this paper studies the price transmis- sion mode when price stickiness exists due to production delays. The model firstly employs duration of price reaction as an indicator of price stickiness, then builds a characteristic matrix for duration of price reaction for each sector within the econo- my, and finally calculates the price level of influenced sectors considering both price changes of inputs and characteristic matrix of price reaction duration, by u- sing iterative approach. In this way, the rate of price change can be measured for each sector within the economy during the studied period. The functions of model are divided into three parts: the sectoral rates of price changes at current period; the changes in direct input coefficients; the rate of price change for inputs. The main findings of model include: the cross - section rates of price changes for all peri- ods of price reactions (or price index) ; a time series of price change rates (or price index) for all sectors.
