折衷物价指数:一种新的物价指数计算方法

Eclectic Price Index:A New Way to Count Price Index

拉氏指数和帕氏指数是当前广泛采用的反映物价变动水平的两种指数,然而两种指数在反映物价变动水平时存在一定的缺陷:拉氏指数会高估而帕氏指数会低估物价变动对消费者产生的影响,均会比较大地偏离消费者的真实生活成本变化。折衷指数是将拉氏指数和帕氏指数综合起来考虑的一种计算物价指数的新方法,能更真实有效地反映生活成本的变化。

The Laspeyres price index and Paasche price index are two indices that are used universally to reflect the price change in the present statistics system, but there are some deflects yet. The Laspeyres price index will enlarge the influence of price change to consumer and the Paasche price index will reduce that. Both of them will deviate from the real cost-of-living change largely. Eclectic price index is a new way to count price index by taking both of them into account, so it can reflect cost-of-living more truly and more effectively.
