根据经济指数理论和消费者偏好差异，构造基于GFT直接效用函数的可变偏好生活成本指数，并编制和比较1996-2011年中国城镇地区七大收入阶层的分层CPI，结果表明：2007年前各分层CPI间的差异相对较小，而在2007年以后差异明显扩大；低收入居民的分层CPI高于高收入居民的分层CPI；城镇居民CPI总指数近似反映了“中等偏上收入”阶层生活成本变化情况，而其他阶层居民则易对CPI总指数“感觉失真”，2007年以来城镇地区CPI总指数的代表性逐渐降低。因此，针对不同收入阶层编制分层CPI，既能更好地反映各阶层居民的通货膨胀压力，维护CPI的权威性，还能为政府科学决策提供更为准确的信息。
根據經濟指數理論和消費者偏好差異，構造基于GFT直接效用函數的可變偏好生活成本指數，併編製和比較1996-2011年中國城鎮地區七大收入階層的分層CPI，結果錶明：2007年前各分層CPI間的差異相對較小，而在2007年以後差異明顯擴大；低收入居民的分層CPI高于高收入居民的分層CPI；城鎮居民CPI總指數近似反映瞭“中等偏上收入”階層生活成本變化情況，而其他階層居民則易對CPI總指數“感覺失真”，2007年以來城鎮地區CPI總指數的代錶性逐漸降低。因此，針對不同收入階層編製分層CPI，既能更好地反映各階層居民的通貨膨脹壓力，維護CPI的權威性，還能為政府科學決策提供更為準確的信息。

According to economic index theory and consumers preference difference, this paper constructs changeable preference living cost index based on GFT direct utility function, works out and compares stratified CPI in seven income stratified classes in China’ s urban residents during 1996-2011, and the results show that there is relatively small difference between each stratified CPI before 2007, however, the difference is significantly enlarged after 2007, that the stratified CPI in the residents with low income is higher than the stratified CPI in the residents with high income, that overall index of CPI of urban residents approximately reflects the situation of living cost change in the stratified classes with “the income a little more than middle class”, however, other stratified residents usually have“distorted sentiment” to overall index of CPI, as a result, the representation of overall index of CPI in urban areas is reduced, thus, the composition of stratified CPI based on different income classes can not only reflect inflation pressure of each stratified class of the residents to keep the authority of CPI but also provide accurate information for governmental scientific decision-making.
