基于四川省2012年的投入产出表,采用改进的投入产出价格影响模型,分析天然气价格变动对四川省其他部门产品价格与物价总水平的影响。结果表明:当同时考虑政府管制和市场供求关系时,天然气上游和下游产品价格一次性下跌30%,将会导致四川省物价总水平下降0.9024百分点。由于政府管制和供求关系的影响,导致其他产业部门的产品价格变动、物价水平变动都要小于传统模型测算的结果,从而使天然气价格传导机制不能有效地发挥其市场资源配置的作用。
Based on the input-output table of Sichuan Province in 2012, this paper uses an improved input-output price impact model to analyze the effect of natural gas price changes on the product prices and general price levels of other departments in Sichuan Province. The results show that when considering the relationship between government regulation and market supply and demand, the prices of upstream and downstream natural gas products will drop by 30% at a time, resulting in a decrease of 0.9024 percentage points in the overall price level of Sichuan Province. Due to the influence of government regulation and supply and demand, the price changes of other industries are less than those of the traditional model. As a result, the price transmission mechanism of natural gas can not effectively play the role of market resource allocation.
