投入产出粘性价格模型研究

投入产出价格影响模型考察了部分产品价格的变动,而引起其他产品价格或整体物价水平的变动程度。多年来,学者们设计了很多扩展的价格影响模型,并仍在不断改进。但是绝大部分改进模型仍被困于不存在价格传导影响的假设之下,即所谓的价格传导阻滞。通过本研究的分析,发现价格传导是否顺畅对价格变动的影响具有相当大的差异。因此,对于价格传导条件的修正就显得至关重要。基于此,本文依据价格粘性理论,特别吸取了费希尔模型的特点,针对现有模型的价格传导机制等方面进行了有效改进,并使其更加符合实际情况。最后,本文利用中国1992年至2007年的实际数据对改进后的价格影响模型进行实证分析,考察了在价格粘性情况下某产业部门产品价格的变动对整个中国经济的短期影响情况。

Research on an Input-Output Sticky-price Model

Input-output price model is able to calculate the change of price on other products or the whole price index induced by the changes in the price of some products.Over the years,scholars have tried to improve it,designed a lot of extended models and continued to refine the models.According to this research,we find that the degree of smoothness of prices' transmission makes the result greatly different.However,the vast majority of the improved models are still trapped in the assumption that price block does n...
