这个是IMF的WEO (World Economic Outlook)的数据。一共189个国家，你想要的国家应该在里面了。另外个人可支配收入比较难找，我就用GDP per capita代替了。先收500个币，楼主要是满意再看着给吧。

还有GDP之间的比较不容易处理，我下载了这些供你选择：
Gross domestic product, constant prices (National currency)
Expressed in billions of national currency units; the base year is country-specific. Expenditure-based GDP is total final expenditures at purchasers’ prices (including the f.o.b. value of exports of goods and services), less the f.o.b. value of imports of goods and services. [SNA 1993]

Gross domestic product, constant prices (Percent change)
Annual percentages of constant price GDP are year-on-year changes; the base year is country-specific . Expenditure-based GDP is total final expenditures at purchasers’ prices (including the f.o.b. value of exports of goods and services), less the f.o.b. value of imports of goods and services. [SNA 1993]

Gross domestic product, current prices (National currency)
Expressed in billions of national currency units . Expenditure-based GDP is total final expenditures at purchasers’ prices (including the f.o.b. value of exports of goods and services), less the f.o.b. value of imports of goods and services. [SNA 1993]

Gross domestic product, current prices (U.S. dollars)
Values are based upon GDP in national currency converted to U.S. dollars using market exchange rates (yearly average). Exchange rate projections are provided by country economists for the group of other emerging market and developing countries. Exchanges rates for advanced economies are established in the WEO assumptions for each WEO exercise. Expenditure-based GDP is total final expenditures at purchasers’ prices (including the f.o.b. value of exports of goods and services), less the f.o.b. value of imports of goods and services. [SNA 1993]

Gross domestic product per capita, constant prices (National currency)
GDP is expressed in constant national currency per person. Data are derived by dividing constant price GDP by total population.

Gross domestic product per capita, current prices (National currency)
GDP is expressed in current national currency per person. Data are derived by dividing current price GDP by total population.

Gross domestic product per capita, current prices (U.S. dollars)
GDP is expressed in current U.S. dollars per person. Data are derived by first converting GDP in national currency to U.S. dollars and then dividing it by total population.

Gross domestic product based on purchasing-power-parity (PPP) valuation of country GDP (Current international dollar)
These data form the basis for the country weights used to generate the World Economic Outlook country group composites for the domestic economy.

The IMF is not a primary source for purchasing power parity (PPP) data. WEO weights have been created from primary sources and are used solely for purposes of generating country group composites. For primary source information, please refer to one of the following sources: the Organization for Economic Cooperation and Development, the World Bank, or the Penn World Tables.
