THE OECD INPUT-OUTPUT DATABASE
PART 1 SOURCES AND METHODS
1.INTRODUCTION
The development of the OECD Input-Output (I/O) databa is part of the STructural ANalysis (STAN) exerci undertaken in the Economics Analysis and Statistics Division of the OECD Directorate for Science, Technology and Industry. Despite the important role of input-output statistics in both national accounts and economic analysis, comparable input-output tables for OECD countries have never been developed by the OECD Secretariat, and little policy analysis has been carried out using this type of economic statistics. This first publication of the OECD input-output tables eks to fill this gap in both statistics and analysis and provide new internationally-comparable data for consistent industrial analysis at a detailed ctoral level.
The compilation work of this databa was initiated in the mid-1990s to assist the OECD Industry Committee in making international comparisons of structural adjustment in industry (e OECD (1992), Structural Change and Industrial Performance: A Seven Country Growth Decomposition Study, OECD Documents ries, Paris). That project provided the initial rationale for developing the Input-Output dat
aba and, since then, work on updating and extending the databa has continued in the EAS Division, in clo co-operation with statistical offices and experts in Member countries. To assist the compilation work and permit the u of internationally-comparable I/O tables, an Expert Workshop was held in March 1993 at the OECD Headquarters in Paris.1 Moreover, this first OECD input-output project revealed the utility of using input-output techniques to analy economic issues at a ctoral level and, as a robust empirical tool, the databa has to date been utilid in a variety of analytical projects carried out in the Directorate, covering structural change, technology diffusion, productivity growth, globalisation and employment.2烫刘海发型图片
The applied input-output work carried out in the EAS Division has, on the other hand, forced the Secretariat to confront the gap that exists between the theoretical u of input-output data that assumes the availability of consistent and complete data and reality, where compromis must be made. In addition, this work has expod some of the large inconsistencies in definitions and treatments existing between national exercis and the international standards reprented by the SNA (the United Nations’ System of National Accounts), which can significantly affect international comparisons.3 In many cas, there is no one correct answer to the problems faced in the applied u of input-output data at the international level. And in some instances, it is likely that urs are not even aware of all the problems that exist.
The OECD Input-Output databa in its current form is also subject to such inconsistencies, although considerable efforts have been made to impo some uniformity by sharing information about national practices with authorities in Member countries, and by identifying problem areas with them. It may be possible to reconcile tho inconsistencies remaining in this first publication in a later version to the extent that further data reconciliation is carried out in national statistical offices and comments from databa urs can be incorporated. Although the number of countries included in this databa is limited (10 OECD countries), the Secretariat hopes that this publication can be ud for comparisons and contribute to further harmonisation of national input-output exercis in Member countries.
Part One of this publication provides basic information on the databa and is organid into broad topics -- basic format, units, coverage, industry classifications, international comparability, etc. More detailed descriptions of each country’s I/O tables are given in the Country Notes appended to Part One. Part Two prents detailed data of the national input-output tables included in the databa. Becau the full databa consists of more than 500 tables, the printed version of this publication includes only the so-
called competing-import input-output tables for each country in each time period. The complete data
ba is available in electronic form.

2.THE OECD INPUT-OUTPUT FORMAT
The most unique feature of the OECD input-output tables is that they break down inter-industrial transaction flows of goods and rvices into tho that are domestically-produced and tho that are imported, and into intermediate and capital goods. The databa thus consists of six elements (Figure 1):
•domestic intermediate goods flows sub-matrix of the I/O tables;
•imported intermediate goods flows sub-matrix of the I/O tables;
•domestically-sourced investment goods flows sub-matrix of the I/O tables;
•imported investment goods flows sub-matrix of the I/O tables;
•sub-matrices of final demand vectors for expenditures on both domestic and foreign products;
•the sub-matrix of value-added ctors.鼎尖教案

Basically, national statistical agencies or input-output experts in countries, rather than the OECD Secretariat, were asked to provide the OECD with the matrices by suitably converting their national tables to the format specified by the OECD and described in detail below. This approach wa
生日快乐字s adopted for two reasons: limited OECD resources; and the fact that, in some instances, a clean map between national categories and the OECD industrial classification bad on ISIC cannot be made, necessitating the creation of estimates which could only be made by the national authorities themlves. Nevertheless, this
approach means that some inconsistencies between countries undoubtedly exist in the conversion of national industries to international standards.

3.TIME AND COUNTRY COVERAGE
Member countries were asked to supply a complete t of matrices for at least three years, with one year situated prior to the first oil-shock in 1973, the cond in the late 1970s, and the third as late as possible in the 1980s (Table 1). In addition, the databa has recently been extended to cover 1990 for most countries except Italy and the Netherlands.
