在我国,考察价格水平的变动时一般只注重价格水平的纵向比较,或者说是一种时间序列的比较。目前编制的各种价格指数都是反映时间序列的纵向比较,它们不能完全满足经济分析的需要。例如,要比较不同地区价格水平、收入和生产水平等的差异,首先需要对地区间的价格水平进行横向比较。不同区域价格之间的横向比较,也叫相对价格水平的研究。目前国际上对这方面的研究方兴未艾,而在我国基本上还是一个空白。这里对价格水平的横向比较问题作一简要介绍,以期引起我国经济理论界和物价及经济管理部门的重视。价格水平的横向比较,就其范围而言,通常包括国家间和地区间的比较两种。除价格水平的横向比较以外,还有对收入、生产、财富等等的比较,但它们都是以价格水平的比较为基础进行的。一般统称它们为国际比较或者地区比较。国际比较要牵涉到不同国家的汇率问 In our country, examining the changes in price levels generally focuses only on longitudinal comparison of price levels, or a comparison of time series. The current price indices compiled are all longitudinal comparisons that reflect time series and do not fully meet the needs of economic analysis. For example, comparing differences in price levels, incomes, and production levels in different regions requires first a horizontal comparison of price levels across regions. Horizontal comparison between prices in different regions, also known as the relative price level of the study. At present, the research in this area is still in the ascendant in the world, but it is still basically a blank in our country. Here a horizontal comparison of the price level to make a brief introduction, with a view to causing our economic theory and price and economic management departments attention. The horizontal comparison of price levels, in terms of their scope, usually includes two more intercountry and interregional comparisons. In addition to the horizontal comparison of price levels, there are comparisons of income, production, wealth, etc., but all are based on a comparison of price levels. They are generally referred to as international comparisons or regional comparisons. International comparison to involve the exchange rate of different countries asked
