中国：按购买力平价（PPP）衡量的人均居民及非营利机构最终消费支出（现价国际元）历年数据

单位：Current international $

指标解释

World Bank official description / 世界银行官方说明

This indicator provides values for final consumption expenditure per person expressed in current international dollars, converted by purchasing power parities (PPPs). PPPs account for the different price levels across countries and thus PPP-based comparisons of economic output are more appropriate for comparing the output of economies and the average material well-being of their inhabitants than exchange-rate based comparisons. Households and NPISHs final consumption expenditure includes expenditure on goods and services by the Household and NPISH sector for the direct satisfaction of human needs or wants, whether individual or collective. This series has been linked to produce a consistent time series to counteract breaks in series over time due to changes in base years, source data and methodologies. Thus, it may not be comparable with other national accounts series in the database for historical years. The core indicator has been divided by the general population to achieve a per capita estimate. This indicator is expressed in current prices, meaning no adjustment has been made to account for price changes over time. The PPP conversion factor is a currency conversion factor and a spatial price deflator. PPPs convert different currencies to a common currency and, in the process of conversion, equalize their purchasing power by eliminating the differences in price levels between countries, thereby allowing volume or output comparisons of GDP and its expenditure components.

可供参考的中文翻译：本指标提供以现价国际元表示的人均最终消费支出数值，并通过购买力平价（PPPs）进行货币换算。PPP考虑了不同国家的价格水平差异，因此与基于汇率的比较相比，基于PPP的经济产出比较更适合比较经济体产出及其居民的平均物质福利。居民及非营利机构最终消费支出包括住户和非营利机构部门为直接满足人类需求或欲望而对商品和服务支出的费用，无论是个人的还是集体消费。本序列已进行链接处理，以产生一致的时间序列，从而抵消因基准年、源数据和方法变化而导致的序列断裂。因此，其可能无法与数据库中历史年份的其他国民账户序列进行可比性比较。核心指标已除以总人口以获得人均估计值。本指标以现价表示，意味着未对随时间的价格变化进行调整。PPP换算因子既是货币换算因子，也是空间价格平减指数。PPP将不同货币换算为共同货币，在此过程中通过消除各国之间的价格水平差异来平衡其购买力，从而实现GDP及其支出组成部分的规模和产出比较。

数据口径与风险提示

• 本指标采用现价国际元，不剔除了价格变动影响，因此时间序列比较受通货膨胀和汇率波动干扰。
• PPP换算因子每若干年会更新基准年，数据库对历史数据进行了链接处理，但与原始数据可能存在口径差异。
• 人均指标使用总人口计算，未区分城镇与农村、就业与失业人口的消费结构差异。
• 指标反映的是住户和非营利机构的直接消费支出，不包括政府公共服务消费和资本形成。
• 跨国比较时，PPP转换因子本身基于一篮子商品价格，存在基期选择和方法论差异。
• 本指标不反映收入分配状况，高人均消费不一定意味着居民福祉分配均衡。
