新疆维吾尔自治区作为我国西部大开发的战略地区,其价格总水平与全国基本上保持一致,但是零售商品物价(RPI)却远远高于全国的平均水平(约合20个百分点),这严重地影响了新疆居民的生活质量。文章根据新凯恩斯主义的AD-AS理论,通过运用联立方程模型与VAR模型对其影响因素做出了分析,研究发现新疆运费成本是造成当前RPI偏高的贡献度约为25%,成为最主要的影响因素,供求冲击对新疆RPI存在较长期的效应,并且发现新疆RPI存在着明显的刚性现象。
As a strategic area for the large-scale development of western China, Xinjiang Uyghur Autonomous Region basically maintains its price level in line with that of the whole country. However, the retail price of commodity (RPI) is far above the national average (about 20 percentage points) Affecting the quality of life of Xinjiang residents. According to the new Keynesian theory of AD-AS, the article analyzes the influencing factors through the simultaneous equations model and the VAR model. It is found that the contribution cost of freight in Xinjiang is about 25% of the current high RPI, becoming the most The main influencing factors, the impact of supply and demand on Xinjiang RPI have a longer-term effect, and found that Xinjiang RPI there is a clear rigid phenomenon.
