中国：按购买力平价 (PPP)计算的人均 GDP（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 domestic product (GDP) 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 domestic product is the total income earned through the production of goods and services in an economic territory during an accounting period. It can be measured in three different ways: using either the expenditure approach, the income approach, or the production approach. 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：该指标提供以现价国际元表示的人均国民总收入 (GDP) 数值，按购买力平价 (PPP) 换算。购买力平价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物质福利水平。国民总收入是一定时期内一个经济体内所有居民生产者创造的增加值加上任何产品税并扣除任何未计入产品价值的补贴后的总和。国民总收入可以通过三种方式进行核算：支出法、收入法或生产法。本序列经过链接处理，以产生一致的时间序列，应对因基年、源数据和方法变化而导致的序列断点。因此，该序列与数据库中历史年份的其他国民账户系列可能不具可比性。该核心指标除以总人口得到人均估计值。该指标以现价表示，意味着未对随时间的价格变化进行调整。PPP 转换因子是一种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，在此过程中通过消除国家间价格水平的差异来使购买力相等，从而实现 GDP 及其支出分量的体量或产出比较。

数据口径与风险提示

• 该指标以现价表示，未剔除通货膨胀影响，不同年份的数值变化包含价格变动因素
• PPP转换因子基于国际比较项目 (ICP) 调查数据，基期和调查年份的变化可能影响时间序列一致性
• 跨国PPP比较依赖于统一的核算方法和价格篮子，不同版本的世界银行数据可能因基准调整而产生差异
• 人均GDP反映的是整体经济规模除以总人口，未考虑收入分配状况，无法直接等同于居民实际生活水平
• 人口数据采用事实定义（de facto），统计口径可能因各国人口普查方法和数据修订而存在差异
• 中国等转型经济体在统计方法改革期间可能存在历史数据的口径不一致问题
