A report of the research about

I-O table making in the world

 

        Although UNIDO (United Nations Industrial Development Organization) once collected I-O tables in the world, no agency grasps the information now. Therefore, in 1999 spring, I asked UNIDO Tokyo office for help and under their support, I surveyed the status of I-O table making in the world from November in 1999.

    This report is a result of the research. However, this result is a total of answers for this survey from each country, and there may be some errors. I would appreciate it if you let me know the errors you found.

 

1. 83 countries (areas) are making I-O tables in the world

    In this research, I sent survey papers to 199 countries (areas). Among them, I obtained replies from 107 countries (areas) and I confirmed that 83 countries (areas) are making I-O tables. The ratio of I-O tables making countries to non-making countries is 42.6%. (Table 1)

   When looked by each area, in West Europe (70.8%), East Asia (64.7%), South America (58.3%) and East Europe (57.9%), more than 50% countries make I-O tables. However, in North Africa (17.2%) and South Africa (29.2%), less than 30% countries make them. (Refer to ＜attached data＞ about the definition of area classification.)

    As to the appendix table, relatively many countries make “Import table” (30 countries), “Commercial margin table” (20 countries) and “Employment table” (18 countries). “Capital matrix table” is made in only 8 countries. In addition, “Tax matrix table” is made in some countries in Europe.

Sahara and New Caledonia are excluded and Congo democratic republic is included.

2. Refer to ＜attached data＞ about the countries and areas contained in area classification.

 

2. Occupies 96.6% of GDP, 83.6% of population and 74.2% of area in the world

     The total sum of GDP of countries and areas making I-O tables is US$28,383,800,000,000 and occupies 96.6% of GDP in the world. (According to 1994-1996 data, and differs with countries. The same as to the following.) Total population is 4,812,540,000 and occupies 83.6% of population, and the total area is 98,540,000 k㎡and occupies 74.2% of area in the world.

    When looked by each area, North Africa occupies an extremely low portion of the GDP in the world (19.7%)and the ratio of West Asia (63.5%) and South Africa (78.8%) is not enough.

3. 39 countries (areas) has been making I-O tables since 1995

    Looked at the year (the latest year) when I-O table was made, 39 countries (areas) have been making them since 1995.

    Among the countries belong to the group which make I-O tables before 1989, the table of Turkmenistan is probably the socialism country type; MPS (System of Material Products Balances) table. At present, to say nothing of the former Soviet Union and East Europe, socialism country have been changing MPS type to SNA (A System of National Accounts). Tables of Russia and China have already changed to SNA type.

4. Only Japan, the U.S. and South Korea make I-O tables with more than 400

sectors

    As for the number of sectors in I-O table (the number of row sectors of the most detailed table), tables of the U.S. (498 sectors), Japan (403 sectors) and South Korea (402 sectors) have greatly large number of sectors. Tables of Canada (243 sectors) and Philippine (230 sectors) follow them. Tables of other countries have less than 200 sectors. However, if the industrial structure is taken into consideration, I-O tables of Thailand (180 sectors), Singapore (173 sectors), Indonesia (172 sectors), Taiwan (160 sectors), China (124 sectors), Israel (191 sectors), Australia (178 sectors) and Denmark (130 sectors) can be regarded as complete I-O tables.

    On the other hand, I-O tables of 26 countries (areas), which have less than 50 sectors, were made mainly for the purpose of using as a standard value of GDP statistics. I-O tables, which have 50 to 90 sectors, such as tables of Italy, Hungary and Germany, put emphasis on GDP estimation. And I-O tables, which have 100 sectors, such as tables of England, France and Australia, are made for the purpose of both Input-Output analysis and GDP statistics. (Table4)
