维 基 百科英文版上有很多很多呀。。比如GDP。

The gross domestic product (GDP) or gross domestic income (GDI) is a measure of a country's overall official economic output. It is the market value of all final goods and services officially made within the borders of a country in a year. It is often positively correlated with the standard of living, though its use as a stand-in for measuring the standard of living has come under increasing criticism and many countries are actively exploring alternative measures to GDP for that purpose.
