摘要: 本文根据2001年1月至2008年4月我国CPI篮子的8类居民消费价格分类指数的月度数据,分析了我国CPI波动的特征,并运用Gonzalo和Granger(1995)以及Darrat和Zhong(2002)提出的检验协整系统中的长期驱动力和短期驱动力的方法,从CPI分类指数的角度实证分析了我国CPI波动的长期和短期的决定因素。研究结果显示我国CPI波动的具有明显的结构性,食品、烟酒及用品、交通和通信、娱乐教育文化用品及服务等5类分类指数价格的变动是我国CPI波动的长期驱动力,而食品、衣着、医疗保健及个人用品等5类分类指数价格的变动是短期驱动力。

Abstract: In this paper, we use the data of China’s monthly CPI by Category from 2001.1 to 2008.4 to analyze the characteristic of the fluctuation of CPI by the technique proposed by Gonzalo and Granger(1995) and Darrat and Zhong(2002). The research conclusion shows that the fluctuation of CPI is obviously structural, food, tobacco, liquor and articles, transportation and communication et al. are permanent driving force of the fluctuation of CPI, but food, clothing, health care and personal articles et al. are transitory driving force.
