索马里：按购买力平价 (PPP) 衡量的人均国民总收入（GNI）（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 gross national income (GNI) 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. Gross national income is the total income earned by all residents within an economic territory during an accounting period. It is equal to gross domestic product plus earned income receivable from abroad minus earned income payable abroad. The core indicator has been divided by the general population to achieve a per capita estimate. 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. 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：该指标提供以现价国际元表示的人均国民总收入（GNI）数值，通过购买力平价（PPP）进行货币换算。PPP考虑了不同国家的价格水平差异，因此基于PPP的经济产出比较比基于汇率的比较更适合用于比较经济体产出及其居民的平均物质福利。国民总收入是一定核算期内一个经济体内部所有常住单位形成的收入总和，等于国内生产总值（GDP）加上来自境外的劳动者报酬和财产收入减去支付给境外的劳动者报酬和财产收入。该核心指标除以总人口得到人均估计值。本序列已进行链式处理以生成一致的时间序列，以抵消因基准年、源数据和方法变化而导致的序列断裂。因此，其与数据库中历史年份的其他国民账户序列可能不具可比性。该指标以现价表示，未对随时间的价格变化进行调整。PPP换算因子是一种货币换算因子和空间价格平减指数。PPP将不同货币转换为通用货币，在转换过程中通过消除国家间价格水平差异来均衡购买力，从而实现GDP及其支出组成部分的规模比较。

数据口径与风险提示

• 该指标采用现价表示，未剔除价格变动影响，因此不同时期的数值变化既包含实际经济增长，也包含通货膨胀因素
• 不同基准年的PPP换算因子存在差异，数据库已进行链式处理，但历史数据与采用当期基准年计算的数据仍可能存在口径差异
• GNI与GDP的差异在于净要素收入，中国作为净要素收入净流出国，该指标与人均GDP的比较需要考虑这一因素
• PPP转换消除的是价格水平差异，并不反映货币的实际购买力或汇率走势
• 该指标反映的是全体居民的平均收入水平，无法体现收入分配状况
• 跨国比较时，各国的统计方法和数据质量存在差异，特别是低收入国家的数据覆盖率和可靠性可能较低
• 人均指标受人口结构变化影响较大，劳动力占比变化可能导致人均收入与宏观经济总量走势背离
