几内亚：按购买力平价（PPP）衡量的人均居民最终消费支出（2021年不变价国际元）历年数据

单位：Constant 2021 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 constant 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. The core indicator has been divided by the general population to achieve a per capita estimate. This indicator is expressed in constant prices, meaning the series has been adjusted to account for price changes over time. The reference year for this adjustment is 2021. 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：该指标表示人均最终消费支出，以不变国际美元计价，通过购买力平价（PPP）换算。PPP考虑了各国不同的价格水平，使基于PPP的经济产出比较更适合比较经济体及其居民的平均物质福利，而不是基于汇率的比较。居民和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愿望（无论是个人还是集体）而购买的商品和服务。该核心指标已除以总人口以获得人均估计值。该指标以不变价格表示，意味着该序列已调整以考虑随时间的价格变化。调整的参考年份为2021年。PPP转换因子是货币转换因子和空间价格平减指数。PPP将不同货币转换为共同货币，在转换过程中，通过消除各国之间的价格水平差异来平等其购买力，从而实现GDP及其支出组成部分的产量或产出比较。

数据口径与风险提示

• PPP转换涉及统计估算，存在一定的测量误差
• 人均指标掩盖了内部收入分配的差异
• 非正规经济活动通常未被计入
• 不同国家的消费结构和商品质量存在差异
