## The Symmetric Tables

The combined Use Table showed that each industry consumes a certain mix of products in order to produce its output, and that each product is sold to a variety of domestic industries and final markets. For the analysis of industry linkages and economic impacts, it is more meaningful to represent the Use Table in industry by industry (IxI) form or product by product (PxP) form.

The industry by industry domestic flows table is the platform for the derivation of analytical tables on the structure of the Scottish economy, such as the Leontief Inverse Tables and the Output, Employment and Income Multipliers. The aggregate Industry by Industry Table for Scotland for 2015 is shown below. A note describing the derivation of this table can be found in the Methodology Guide.

## Interpretation of the Symmetric Tables

Note: The following uses the Industry by Industry (IxI) Table for the examples of use. However, a Product by Product Table could be used in the same way.

The structure of the IxI Table is very similar to the Use Table and can be used for similar analyses but, as the rows have been converted from purchases of products to purchases from each industry, a number of additional analyses are possible.

###### Destination of industry output

Where the Use Table showed the destination of manufactured products, the IxI Table shows the destination of manufacturing industry output - be it manufacturing products or other secondary products. From the Use Table, the exports of manufactured products were estimated as £14,214 million (rest of UK) and £14,232 million (rest of world), whereas the IxI Table gives exports by the manufacturing industry (at basic prices) of £10,030 million (rest of UK) and £11,937 million (rest of world).

###### Industry's contribution to GDP

The income measure of Gross Domestic Product (Gross Value Added at basic prices) is defined as the sum of taxes less subsidies on production, plus compensation of employees and gross operating surplus giving a total of £130,431 million for Scotland in 2015. This figure corresponds to the income measure of Gross Domestic Product - GDP(I).

It is possible to estimate each industry's contribution to GDP from the above table by dividing the Gross Value Added (GVA) at basic prices for each industry by the overall total GVA figure. For example, the manufacturing industry contributes approximately 11% (£13,775m) to total Scottish GDP.
