Introduction

This publication contains preliminary input-output tables for 2001–02. The tables presented here are the core transaction tables of the input-output suite of tables compiled by ABS. The full set of tables will be released late in 2006. This is the first set of input-output tables that reflect the structure of the Australian economy following the changes to the indirect tax system, including the introduction of the goods and services tax (GST) on 1 July 2000.

Input-output tables are part of the Australian national accounts, complementing the quarterly and annual series of national income, expenditure and product aggregates. They provide detailed information about the supply and use of products in the Australian economy and about the structure of and inter-relationships between Australian industries.

With the release of tables for 2001–02, the ABS has completed 19 input-output tables for Australia. Previous tables were for 1958–59, 1962–63, 1968–69, 1974–75, for each year from 1977–78 to 1983–84, 1986–87, 1989–90, 1992–93 to 1994–95, 1996–97 and 1998–99. Commencing with the 1974–75 tables, an estimation methodology involving a combination of clerical and mathematical estimation techniques was introduced and it has been used in compiling the current tables.

As part of the process of compiling a balanced set of national accounts, supply-use (S-U) tables are compiled. S-U tables, in both current prices and in the prices of the previous year, are compiled annually and are available on request.

Explanatory notes and classifications are available in electronic form.

Changes

The following changes have been made in this edition:

• with the introduction of the goods and services tax (GST), the tables presenting details of the various taxes on products have been reorganised. Tables 35 through 37 present information in respect of GST, duties and other taxes on products respectively. Table 38 presents information in respect of subsidies on products. Table 34 provides information in respect of the aggregate of these tables (35 through 38), that is taxes on products (net)
  
• the valuation of transactions at basic prices has been changed to better support the analytic uses of input-output tables. Goods are valued at an ex-farm, ex-mine, ex-factory price as far as is practical. This change does not affect any of the main aggregates in the system, but results in a slightly lower level of domestic output of the goods producing industries and the aggregate output recorded in the tables
  
• output of the construction industry is recorded on a gross basis, that is transactions between the primary builder of a new structure and any subcontractor involved in that construction is recorded where in previous editions of the tables these flows were netted out
  
• previously information in respect of coal, oil and gas was presented in aggregate. In this publication the coal product and industry and the oil and gas product and industry groupings are presented separately
  
• the output of the gas industry is treated as a margin and consequently an extra margin table has been introduced. This change has been implemented in order that the treatment of the economic substance of the activity undertaken by this industry, which is analogous to the reselling activity undertaken by wholesalers and retailers, is better reflected in the tables
  
• all imports are treated as competing imports and consequently the complementary imports row is no longer presented because those imports that might be classified as complementary are no longer considered to be of material consequence either at the total economy or individual product group industry level.

• 2111 Wine and spirits has been combined with 2112 Tobacco products the combined estimates recorded against 2113 Wine, spirits and tobacco products
  
• separate identification of coal, oil and gas as noted above
• an additional product and industry group has been introduced within construction, namely 4201 Construction trade service
  
• previous product and industry groups 5401 Mechanical repairs and 5402 Other repairs,have been split into groupings 4502 Wholesale mechanical repairs and 5102 Retail mechanical repairs; and 4503 Other wholesale repairs and 5103 Other retail repairs,respectively.
