The data used in preparing the input-output table for the Vietnamese economy come from a 1997 Social Accounting Matrix (SAM) for Vietnam documented in Nielsen, Chantal Pohl (2001) Social
Accounting Matrices for Vietnam: 1996 and 1997. Working Paper No. 8/2001, Danish Institute of Agricultural and Fisheries Economics (SJFI), Copenhagen. The original data sources used to construct the SAM include national accounts statistics,
government budget data, the official 1996 input-output table, the 1997/98 Vietnam Living Standards Survey (VLSS), and COMTRADE trade data. In its full disaggregation, the SAM includes 97 producing sectors. The agri-food sectors are well represented: there are eight primary agricultural sectors, two agricultural service sectors, and 13 food processing industries. There are five factors of production (three types of labor distinguished by skill level, one type of capital and one type of land), six household types (distinguished by rural/urban, agricultural/non-agricultural, wage/selfemployed), and one account each for enterprises, government, investment/savings and rest-of-world.
The rest-of-world account is a purely non-trade-related account that keeps track of financial transfers between Vietnamese institutions (households, enterprises, government, etc.) and the rest of the world. This is because imports and exports are distinguished by trading partner in this particular SAM, more specifically, 94 partner countries are identified. The unit of accounts are billions of Vietnamese Dong and the flows in the SAM include margins.
