Gross domestic product at market prices

GDP (gross domestic product) is an indicator for a nation´s economic situation. It reflects the total value of all goods and services produced less the value of goods and services used for intermediate consumption in their production. Expressing GDP in PPS (purchasing power standards) eliminates differences in price levels between countries, and calculations on a per head basis allows for the comparison of economies significantly different in absolute size.国内生产总值（Gross Domestic Product，简称GDP）是衡量一国经济运行状况的核心指标，其核算范围为全部已生产商品与服务的总价值，扣除生产过程中用于中间消耗的商品与服务的价值。以购买力标准（Purchasing Power Standards，简称PPS）核算GDP，可消除各国间的物价水平差异；采用人均核算方式，则可实现经济规模绝对值差异显著的经济体之间的有效比较。
