【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Hedonic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。更多还原

【Abstract】 In this paper we construct a number of quality-adjusted price indexes for personal computers in the China marketplace over the period 1995—2005.Linear and nonlinear hedonic models are estimated using data from personal computers.The results indicate that nominal quality-adjusted prices declined at an average annual rate of 35%.We conclude that taking quality changes into account has an enormous impact on the time pattern of price indexes for(PC’s.)更多还原
