用Hedonic函数估计中国PC机价格指数

Hedonic Price Indexes for Personal Computer

    摘要
  • 摘要: 建立PC机价格指数时样本的质量调整问题变得越来越突出。文章运用线性和非线性的Hedoni c函数估计中国1995～2005年的PC机价格指数。最终的估计结果表明,中国质量调整后的PC 机价格指数平均每年下降35%。从这个结果可见,考虑质量调整对于价格指数的估计结果有 很大的影响。

     

    Abstract: In this paper we construct a number of quality-adjusted price indexes for perso nal computers in the China marketplace over the period 1995—2005. Linear and no nlinear hedonic models are estimated using data from personal computers. The res ults indicate that nominal quality-adjusted prices declined at an average annua l rate of 35%. We conclude that taking quality changes into account has an enorm ous impact on the time pattern of price indexes for PC-s. 
