GDP, GNP, NNP, NIP, NNP, NI are all figures showing one region's economy.

GNP is Gross National Product.
GDP is different from GNP.
GDP only calculate the economy activities within one region but for GNP, it calculates the income of the residents.
Simply, GDP is always calculated by the resident producing units....that usually in a company-form, of their production or expenditure.
For GNP, it is used to calculate income.
NNP means GNP net depreciation. This is not common to ask in HKCEE~
