3. Gross Provincial Product : GPP
National accounts for the country 3 approaches :
Production, Expenditure and Income
GDP estimation via the production approach is
necessary for the country.
Top-down approach is used to disaggregate VA of
each activity of the country level to regional /
provincial level.
GPP estimation normally bases on 2 methods

4. First method
Use only for agricultural sector
Because of basic data is relatively perfect
Production, price are available in provincial level
But intermediate cost structures are available in
regional level
Compute VA of each agricultural commodity at
regional level and then disaggregate to provincial level
VAregion i = GOregion i - ICregion i
VAprovince j = VAregion i x Prod. ratio ij

5. Second method
Use for all commodities in other sector
No have data on production, price and
intermediate consumption at regional and
provincial level
VA of each commodity at the country level are
disaggregated to each province by proportion of
relative production indicators to the country
VAprovince k = VAcountry x Prod. Ratiok

6. GPP & GRP presentation
ISIC rev. 3 has been used
16 economic sectors
(exclude: Extra-territorial organization)
Current prices
Constant prices at 1986 prices
GRPi = sum of GPP in region i
Population and per capita GPP are presented
13 months lag for dissemination

7. Problem
It’s not technically perfect
Because of
o Not reflect prices in difference region / province
o IC is same proportion in every region / province
Accounting system can not be completed due to
unadequate data
Many activities do not have a clear boundary,
producing places and marketing spots are far away
from each other.
o Transportation : mobile from one boundary to another, railroad
o Electricity generating, marine fishery, mining in the sea
o Mobile phone

8. Bottom-up approach
In order to get the economic situation in each area
correctly.
Since 2004: NESDB encourage each province (exclude
BKK) to do GPP for themselves.
NESDB provide GPP concept and compilation
methodology to local agency’s staff.
Little by little of quality of GPP-Bottom up are observed.
NESDB still publicizes GPP officially (Top down).
GPP statistics of each province can be utilized for his
own provinces in term of primary economic report.

9. Problem of Bottom-up approach
Incomplete of data collection
Hard to get data in some activity eg. Trade: head office
locate at BKK , the branch which in another province
no have accounting data
Very often changing the local staff who are
responsible for GPP compilation
Budgetary constraint
