CONSTRUCTION STEPS
Step 1: Harmonization of data
Step 2: Construction of import matrices
by country of origin
Step 3: Linking and balancing
1.1 The year of reference: update (or backdate)
the table using the information from the national
accounts of the reference year.
1.2 Valuation: transform the table into the uniform
valuation scheme, either in basic price or
producer’s price, using the relevant information
from the supply table such as the matrix of taxes
on products, of trade and transport margins.
1.3 Presentation format: adjust the table for special
statistical treatments, such as FISIM, scraps and
by-products, dummy sectors.
1.4 Product classification: aggregate/disaggregate
the product sectors in the original table, and
redefine them into the common classification.

Similarity to the
Japanese I-O table
2.1 Construct a CIF import matrix: use survey
information to determine the input-output structure of
imported products. Harmonise the treatment of
CIF/FOB adjustment, margins on imported goods,
re-export/re-import. Need to match the row-totals of
the matrix with the import data from foreign trade
statistics (both for goods and services).
2.2 Split the CIF import matrix into matrices by
country of origins: use foreign trade statistics and,
ideally, the survey information on the distribution of
imported items by domestic users.
2.3 Convert the matrices from CIF to basic
price/producer’s price: use the relevant information
on taxes and margins of partner countries.

3.1 Redefine the concordance between the uniform
I-O classification and national I-O classification, or
even HS coding.
3.2 Apply RAS algorithm to establish row-column
balances.
3.3 Consistency check with other statistical sources
And …that’s it !!
