OECD Bilateral Trade Database - by Industry and by End-use (BTDIxE)

WPTGS – 8th November 2011

why btdixe
Why BTDIxE ?
  • To better understand structural changes in international trade
  • Contribute to analyses of global production networks, regional integration etc. via linking of national Input-Output tables e.g. work of CIIE
  • Input into OECD Trade in Value Added project
  • General tool for empirical analyses to address policy issues in areas of Trade, Industry, infrastructure, environment, innovation …
  • Replaces existing OECD Bilateral Trade by industry Database (BTD)
coverage
Coverage
  • Exports and imports of goods, 1988-2010
  • Countries(reporters and partners)
    • 34 OECD countries
    • 30 non-Members to cover (or complete) BRIICS / EU27 / G20 / ASEAN9 / CEFTA
    • Two additional partners = Rest of World and Unspecified
  • Industries
    • About 40 activities mainly covering agriculture, mining and manufacturing: generally 2-digit ISIC Rev.3

+ 4 technology intensity groups

+ 8 categories of waste, scrap, recycled goods

end use categories
End-use categories

Broad Economic Categories (BEC) codes in parentheses

btdixe end use categories
BTDIxE end-use categories
  • 3 SNA end-use categories
    • Intermediate inputs
    • Household consumption
    • Capital goods
    • 5 mixed end-uses
    • packed medicaments
    • personal computers
    • passenger cars
    • phones (fixed and mobile)
    • valuables

+ other n.e.c

(fuels and lubricants currently allocated to intermediate goods)

sources and methods
Sources and Methods
  • Source = OECD ITCS / UN Comtrade annual merchandise trade statistics (HS 6 digit level = approx. 5000 products)
  • Standard conversion keys from HS to ISIC and HS to End-use category (EUC) developed for each version of HS (1988, 1996, 2002, 2007) and applied to data according to reported HS. Thus, 8 conversion keys
  • Specific adjustments for Hong Kong re-exports
  • Treatment of confidential trade at 2-digit HS level
  • Other adjustments (country specific)
generation of conversion keys used for btdixe via existing unsd correspondence tables
Generation of conversion keys used for BTDIxEvia existing UNSD correspondence tables

BEC (part): Certain HS products have been allocated to end-uses different to those implied by UNSD HS BEC  end-use conversions

confidential trade
Confidential trade
  • Some confidential trade at the 2-digit HS chapter level can be allocated to ISIC and/or end-use
  • Generally apparent as the difference between 2-digit HS data and sum of 6-digit components
  • In the past, such confidential trade, and other “special transactions”, reported (in OECD ITCS) with codes nnCF00 or nnEUxx – for 2-digit chapter nn
  • Used less frequently in recent years and not present in the ‘official’ UNSD HS-HS, HS-ISIC, HS-BEC correspondences (only regular HS 6-digit codes used)
  • Therefore, in BTDIxE, differences between 2-digit and sum(6-digit) data are calculated (code nnADJS) before conversion keys applied
hong kong re exports
Hong Kong re-exports
  • Adjustments for Hong Kong re-exports to get better estimates of bilateral flows to and from China
  • Use re-exports by origin and destination from Hong Kong Customs and Statistics Department
  • Allows for China  Hong Kong  China case
other adjustments
Other adjustments

Done

  • Extending estimates for some reporters e.g.
    • Belgium, 1988-92 : using Belgium-Luxembourg figures
    • South Africa, 1992-99 : South Africa Customs Union (SACU)
    • Chinese Taipei, from 2007: “Asia not elsewhere specified”

Desired

  • Re-export adjustments for other major hubs such as Netherlands and Singapore
  • Country specific adjustments e.g. for UK to deal with distortions in ICT trade (mid 2000s) due to EU VAT fraud
  • Dealing with second-hand goods not identified in HS either for re-use e.g. transport equipment, or recycling e.g. discarded PCs
next steps
Next steps
  • Finish comparisons between BTDIxE and similar results from WIOD project

understand origins of any differences

  • FinaliseBTDIxE documentation and publish as OECD STI Working Paper(s)

Zhu, Yamano and Cimper, 2011 (forthcoming)

  • Release data on OECD.STAT

replacing existing BTD

  • Use for inter-country I-O analyses (e.g. TiVA)
  • Identify areas for improvement
  • Dealing with ISIC Rev. 4
