Introduction
This publication presents information on supply and exports by detailed product item based on the 1998-99 Input-Output Product Classification (IOPC). A separate publication Australian National Accounts, Input-Output Tables - Electronic Publication (5209.0.55.001) provides a comprehensive range of input-output flow and coefficient tables.
Table
The table is titled Table 1. Product supply and exports by Input-Output Product Classification (IOPC) item, 1998-99. It comprises a list of IOPC product items and shows, for each product item and group, the value of supply in 1998-99, its source (Australia production or imports) and the value of exports. Product values shown in this table can be directly related to Tables 1, 2 and 3 of 5209.0.55.001.
For each product group total in the table of this publication, entries in the column headed total are equal to those in column total supply (T6) in Table 2. Use table - input by industry and final use category and supply by product group, of 5209.0.55.001.
Entries in the column headed exports are equal to those in the column exports (Q7) for each product group in Table 2 of 5209.0.55.001.
The value of Australian production for each product group is equal to the total Australian production for the corresponding product group in Table 1, Supply table - supply by product group by industry and imports, of the 5209.0.55.001.
The value of competing imports c.i.f. for each product group is equal to total supply (T6) for the corresponding product group in Table 3. Imports - supply by product group and inputs by industry and final use category, of 5209.0.55.001. It is also equal to competing imports (P6), shown in Table 2. Use table - input by industry and final use category and supply by product group, of 5209.0.55.001. Although competing imports for each product are valued, cost, insurance and freight (c.i.f.) the aggregate imports estimates are valued free on board (f.o.b.)
The value of complementary imports is equal to the total for complementary imports in Table 3, Imports - supply by product group and inputs by industry and final use category, of 5209.0.55.001. It is also equal to complementary imports (P5), shown in Table 2, Use table - input by industry and final use category and supply by product group, of 5209.0.55.001.
Classifications
The IOPC is an industry-of-origin product classification that has been specifically developed for the compilation and application of Australian input-output tables. Because the input-output system describes the production and subsequent use of all goods and services, an input-output product classification needs to be defined in terms of characteristic products of industry sectors. The overall principles for the preparation of such an industry-of-origin product classification are:
- homogeneity of inputs - each product or product group should consist of items that have similar input structures or technology of production. This principle is generally applied through the definition of each IOPC item in terms of the ANZSIC industry sector in which it is mainly produced.
- homogeneity of disposition - each product or product group, having satisfied the first criterion, should consist of items that have similar patterns of disposition or usage. This principle is applied by reference to the description of source data items and information about the transport, distribution and product taxation margins applying to particular products.
The 1998-99 IOPC is consistent with the 1993 edition of the Australian and New Zealand Standard Industrial Classification (ANZSIC).
At its most detailed level the IOPC comprises approximately 1000 individual product items. For confidentiality and data availability reasons the values of some of these detailed products are aggregated in this publication.
This edition of the IOPC is also consistent with the Australian and New Zealand Standard Commodity Classification (ANZSPC) and 1998-99 Harmonised Commodity Description and Coding System (HS) at the 6 digit level.
Structure of the IOPC
The structure of the IOPC arises from its industry-of-origin basis. In an industry-of-origin classification, each product item is shown according to the industry in which it is primarily produced. Thus, the structure of the IOPC consists of industry-of-origin headings with detailed product items shown under each heading.
This structure is implemented in the IOPC by the adoption of ANZSIC classes as the basis for defining IOPC items. IOPC items are identified by an eight digit code with the first four digits referring to the ANZSIC class to which the item is primary and the last four digits the product number. Details of ANZSIC codes and their relationship to the input-output industry classification is shown in Appendix A.
