物价总水平指标体系由各类价格水平的相对数即指数所构成。它是宏观经济指标总体系的重要组成部分,具有综合性经济指标体系的性质。一般所说的物价总水平,是指在一定时期内各种商品和劳务价格的平均水平而言,它是一个动态指标,总是随着经济等因素的变化而波动的。为了能够反映物价总水平的变动趋势和程度,就须借助各类价格水平的相对数即物价指数来反映计算期同特定时期相比显示出的差异情况,如大体持平、上升或下降及其程
The overall price index system consists of the relative number of various price levels, that is, the index. It is an important component of the overall system of macroeconomic indicators and has the nature of a comprehensive economic index system. Generally referred to as the general price level, it refers to the average level of prices of various commodities and services within a certain period of time. It is a dynamic indicator and always fluctuates along with changes in economic and other factors. In order to be able to reflect the trend and degree of changes in the general price level, the relative price of various price levels, that is, the price index, must be used to reflect the difference between the calculation period and the specified period, such as the general level, increase or decrease, and its duration.
