GDP vs GNP
Gross domestic product (GDP) is defined as the "value of all final goods and services produced in a country in one year" . On the other hand, gross national product (GNP) is defined as the "value of all (final) goods and services produced in a country in one year, plus income earned by its citizens abroad, minus income earned by foreigners in the country". The key difference between the two is that GDP is the total output of a region, eg. America , and GNP is the total output of all nationals of a region, eg. Americans.
To give an example of the difference between GDP and GNP, and also income, using America :





National income and output (Billions of dollars)



Period Ending


2006



Gross national product


11,059.3



Net U.S. income receipts from rest of the world


55.2



U.S. income receipts


329.1



U.S. income payments


273.9



Gross domestic product


11,004.1



Private consumption of fixed capital


1,135.9



Government consumption of fixed capital


218.1



Statistical discrepancy


25.6



National Income


9,679.7


GNP is becoming less used, as a larger number of nationals are working in nations abroad. Because of this, GDP is becoming a more popular measure.
國民生產總值（英語：Gross National Product，簡稱GNP），也稱國民生產毛額、本地居民生產總值，即一國一年內所生產的最終產品（包括勞務）的市場價值的總和，是國民收入核算中最重要的組成部分。在經濟學上，由於不同角度，對國民生產總值的計算方式也有多種。




產品流動法（Flow of Product Approach）
所得收入法（Earnings or Income Approach）
部門法（Sector Approach）

從理論上說，上述3種方式最後統計得出的結果應該是一致的。現在國際上計算國民生產總值的通行方法為FPA，並將它得出的數據作為標準。
計算公式：Q1P1＋Q2P2＋……＋QnPn ＝ 國民生產總值

Q代表各種勞務與最終產品（Final Products），即不包括生產各環節中重複計算的部分。
P代表勞務與最終產品的價格。
