1. 1 Reviewing the nomenclature for high- technology trade – the sectoral approach by Alexander Loschky

2. 2 Current high-tech nomenclature Two different approaches: –Sectoral approach (by economic sectors, ISIC / NACE) –Product approach (by product groups, SITC) This presentation concentrates on the sectoral approach.

3. 3 R&D intensity is used as the sole indicator Calculating direct and indirect R&D intensities –Direct R&D intensities: –Indirect R&D intensities (R&D expenditure embodied in the intermediate goods used in the production of another sector) Calculation: via Input-Output tables How are high-tech sectors identified?

4. 4 Why reviewing the sectoral high-tech classification? Current nomenclature is relatively old: 1997: OECD working paper by Thomas Hatzichronoglou (using direct and indirect R&D intensities, but figures date from 1990) 2005: OECD Handbook on Economic Globalisation Indicators (minor and partial update using only direct R&D intensities)

5. 5 Calculation of indirect R&D intensities (1) Brief description in nine steps: 1.Conversion of input-output tables (nearest to the year 2000) from national currencies into US-$ (using PPP) 2.Estimation of missing output data for certain sectors and countries (where possible) with production data 3.Summing-up of the input-output tables of all countries into a single table

6. 6 Calculation of indirect R&D intensities (2) 4.Calculation of the direct R&D intensities: = total R&D expenditure of sector Y for all countries / total output in sector Y of all countries 5.Conversion of the unified input-output table of step 3 into a table of input coefficients (A) 6.Formation of the Leontief inverse: (I-A) -1 (The Leontief inverse shows the impact of one unit of final demand on the intermediate products.)

7. 7 Calculation of indirect R&D intensities (3) 7.Transformation of the table into a table of output necessities (showing the amounts of intermediate products needed for one unit of output) 8.Calculation of the total R&D intensities: Calculation of indirect R&D intensities (of sector Y from each sector X) : The output necessities of sector Y from each sector X were multiplied with the respective direct R&D intensities of sectors X. Total R&D intensity of sector Y = direct R&D intensity of sector Y + indirect R&D intensities of Y

8. 8 Calculation of indirect R&D intensities (4) 9.The total R&D intensities were used to classify the sectors for its technology intensiveness. The threshold used were: R&D intensity… … below 1.0%: low-tech … between 1.0% and 2.5%: medium-low-tech … between 2.5% and 7%: medium high-tech … higher than 7%: high-tech

13. 13 Results – Impact on the high-tech classification: Almost no changes for the technology classification compared to the last one, based on 1990 data. The only major change: precision instruments are now high-tech and became the sector with the highest R&D intensity. But note: The ranking within the high-tech and medium-high-tech groups changed considerably.

14. 14 Outlook (1) This exercise should be repeated each time when new OECD Input-Output tables become available. Hopefully country coverage (currently 18 countries) can be extended to even more OECD and non-OECD countries. Also the classification based on the product approach needs an update (see paper by Florian Eberth, OECD).

15. 15 Outlook (2) – The combined approach Currently trade by high-tech sectors is calculated using correspondence tables (ISIC  SITC). In the future, this could be replaced by using (detailed) sectoral foreign trade data allowing to identify the goods actually traded by high-tech sectors. Thank you!

17. 17 Additional slide: Country coverage data from 18 countries were used for which R&D intensities could be calculated and for which OECD Input-Output tables were available (compared to 10 countries in 1997) The countries were: AU, BE, CA, CZ, DE, DK, ES, FI, FR, UK, IE, IT, JP, KR, NL, NO, PL, SE, US (all 18 countries are OECD members)
