关于帕氏指数，下列说法中错误的是( )。
A．帕氏指数以报告期变量值为权数
B．帕氏指数不能消除权数变动对指数的影响，因而不同时期的指数缺乏可比性
C．帕氏指数可以同时反映出价格和消费结构的变化，具有比较明确的经济意义
D．帕氏数量指数由于包含了价格的变动，符合计算物量指数的目的，因而在实际中应用得较多
参考答案：D
解析： 帕氏指数以报告期变量值为权数，又称基期加权综合指数。帕氏指数以报告期变量值为权数，不能消除权数变动对指数的影响，因而不同时期的指数缺乏可比性。但是帕氏指数可以同时反映出价格和消费结构的变化，具有比较明确的经济意义。帕氏数量指数由于包含了价格的变动，这本身不符合计算物量指数的目的，因而在实际中应用得较少。
