What are the Input-Output Tables?
The Input-Output Tables are the matrixes which represent interrelationships between each industry. These tables include various kinds of transactions tables, input coefficient tables, and impact coefficient tables, which are described as follows:
1. Transactions Table, or named use table, is the basic table of Input-Output statistics. Each row represents the destination, for intermediate consumption or final use, of commodities. Each column details the production function of a specific commodity, including the value of the commodity’s total output, the mix of commodities it consumes to produce this output and the value added by labor and capital producing this output. The final use columns detail the commodity composition of the final use components of GDP. On the basis of different commodity sources, Transaction Table can be further divided into “Transactions Table of Domestic Goods and Services” and “Transactions Table of Import Goods and Services”. These transactions tables can be valued at different prices.
(1) The purchaser’s price is the amount paid by the purchaser, including transport margins, trade margins and non-deductible VAT.
(2) The producer’s price is the amount receivable by the producer from the purchaser for a unit of commodity produced as output minus transport margins, trade margins and non-deductible VAT.
(3) The basic price is the amount receivable by the producer from the purchaser. It excludes any tax payable, and plus any subsidy receivable.
In our compilation practice, Transactions Table is valued at both producer’s price and purchaser’s price respectively. Transactions Table of Domestic/Import Goods and Services are valued at producer’s price only.
2. Input coefficients tables are used to estimate directly corresponding effects of each industry. These tables are calculated by the following method. Each input of every sector divide individually by gross output of corresponding sector.
3. Impact coefficients tables are used to estimate directly and indirectly corresponding effects of domestic industries resulting from increased (or decreased) quantity of one industry to final users.
