<strong>Trade</strong> Patterns <strong>and</strong> Global Value Cha<strong>in</strong>s <strong>in</strong> <strong>East</strong> <strong>Asia</strong>to de facto economic <strong>in</strong>tegration were first observed <strong>in</strong>Japan, <strong>and</strong> then gradually shifted towards Ch<strong>in</strong>a. Thechapter shows the grow<strong>in</strong>g role of Ch<strong>in</strong>a <strong>and</strong> the relativedecl<strong>in</strong>e of the United States <strong>and</strong> Japan as productionhubs. Other emerg<strong>in</strong>g <strong>East</strong> <strong>Asia</strong>n economies have alsosignificantly <strong>in</strong>creased their degree of <strong>in</strong>tegration <strong>in</strong>to theregional production system, contribut<strong>in</strong>g to strengthen<strong>in</strong>geconomic <strong>in</strong>terdependency <strong>in</strong> the <strong>Asia</strong>-US region.The diversity <strong>and</strong> complementarity of the regionalproduction system also fosters specialization when itcomes to trade <strong>in</strong> tasks. Reflect<strong>in</strong>g their particular roles<strong>in</strong> <strong>global</strong> <strong>value</strong> <strong>cha<strong>in</strong>s</strong>, some countries, like Japan or theRepublic of Korea, specialize <strong>in</strong> the export of products<strong>in</strong>volv<strong>in</strong>g high- or medium-skilled labour, while others,such as Ch<strong>in</strong>a or Viet Nam, focus on low-skilled, labour<strong>in</strong>tensiveactivities. When consider<strong>in</strong>g the totality ofthe <strong>value</strong> cha<strong>in</strong>, from conception to production <strong>and</strong>consumption, developed economies like the UnitedStates tend to create employment at both ends of thequalification spectrum, from highly-skilled eng<strong>in</strong>eers<strong>and</strong> professionals to low-skilled retail workers; however,low-skilled manufactur<strong>in</strong>g tasks are outsourced. Thenet balance of employment is also clearly <strong>in</strong>fluenced bythe overall macroeconomic situation of each economy;net job creation attributable to trade is much higher <strong>in</strong>export-led surplus countries than <strong>in</strong> <strong>in</strong>ward-orientedones, especially when the latter run structural tradedeficits.An exam<strong>in</strong>ation of the historical evolution of productionnetworks <strong>in</strong> the region, which is the purpose of ChapterVII, shows how <strong>Asia</strong>n economies have become<strong>in</strong>terconnected with each other <strong>and</strong> with the US market.In 1985, there were only four key players <strong>in</strong> the region:Indonesia, Japan, Malaysia <strong>and</strong> S<strong>in</strong>gapore. In the 1990s,the Republic of Korea, Ch<strong>in</strong>ese Taipei <strong>and</strong> Thail<strong>and</strong> alsoemerged as important l<strong>in</strong>ks <strong>in</strong> the production network.Japan was extend<strong>in</strong>g its supply <strong>cha<strong>in</strong>s</strong>, while outsourc<strong>in</strong>gfrom the United States was also strongly enter<strong>in</strong>g thepicture. After 2000, the emergence of Ch<strong>in</strong>a altered theregional network, <strong>and</strong> by 2005, the network’s centre ofgravity had clearly shifted there. The <strong>in</strong>termediate goodsimported by Ch<strong>in</strong>a come through relatively long <strong>and</strong>complex supply <strong>cha<strong>in</strong>s</strong>, characterized by a high degreeof fragmentation <strong>and</strong> sophistication. The competitivenessof Ch<strong>in</strong>ese exports is not only attributable to its lowproduction costs, but also to the complex <strong>in</strong>termediategoods imported from other countries, be they from <strong>Asia</strong>or the rest of the world.Chapter VIII is dedicated to the mapp<strong>in</strong>g of trade<strong>in</strong> <strong>in</strong>termediate goods, which constitutes the “bloodstream” that irrigates <strong>global</strong> <strong>and</strong> regional supply <strong>cha<strong>in</strong>s</strong>.<strong>Trade</strong> <strong>in</strong> <strong>in</strong>termediate goods now dom<strong>in</strong>ates worldtrade <strong>in</strong> non-fuel merch<strong>and</strong>ise. While Europe is still thebiggest trader <strong>in</strong> <strong>in</strong>termediate goods, <strong>Asia</strong> has beenrapidly clos<strong>in</strong>g the gap, <strong>and</strong> is now a close second.While <strong>in</strong>termediate goods constitute more than 60 percent of <strong>Asia</strong>’s total imports, <strong>Asia</strong> tends to export moref<strong>in</strong>al goods composed of the imported <strong>in</strong>termediateones. This regional characteristic, <strong>in</strong>herent <strong>in</strong> the region’srole as “Factory <strong>Asia</strong>”, is not equally displayed by eachcountry. Some economies, like Ch<strong>in</strong>a, India <strong>and</strong> VietNam, have dist<strong>in</strong>ctly higher shares of <strong>in</strong>termediate goods<strong>in</strong> their imports than <strong>in</strong> their exports, while the opposite istrue for the Republic of Korea, Japan <strong>and</strong> Ch<strong>in</strong>ese Taipei.Not only has trade <strong>in</strong> <strong>in</strong>termediate goods <strong>in</strong>creased, butthese goods are also <strong>in</strong>creas<strong>in</strong>gly complex.Some trade analysts have argued that the change fromtrade <strong>in</strong> goods to trade <strong>in</strong> tasks implied by the operationof <strong>global</strong> <strong>value</strong> <strong>cha<strong>in</strong>s</strong> is comparable to a paradigm shift <strong>in</strong>the analysis of <strong>in</strong>ternational trade. Because new conceptsalso <strong>in</strong>volve new measurements, Chapter IX exploressome of the changes required to complement exist<strong>in</strong>gstatistical <strong>in</strong>dicators. The complexity of productive <strong>and</strong>commercial relationships has blurred the relevance ofa series of macroeconomic <strong>in</strong>dicators, such as bilateraltrade balances. The concept of “country of orig<strong>in</strong>” isbecom<strong>in</strong>g <strong>in</strong>creas<strong>in</strong>gly difficult to apply to manufacturedgoods, as the various operations that comprise them,from the design of a product to the mak<strong>in</strong>g of itscomponents, their assembly <strong>and</strong> related market<strong>in</strong>g, arespread across the world. Nowadays, products are more“made <strong>in</strong> the world” than “made <strong>in</strong>” a specific country.One way of tak<strong>in</strong>g <strong>in</strong>to account the fragmentation of<strong>value</strong> <strong>cha<strong>in</strong>s</strong> <strong>and</strong> provid<strong>in</strong>g a decomposition of grossexports by domestic <strong>and</strong> foreign orig<strong>in</strong> is by measur<strong>in</strong>gthe <strong>value</strong> added imbedded <strong>in</strong> exports.Measur<strong>in</strong>g trade <strong>in</strong> <strong>value</strong> added uses both trade statistics<strong>and</strong> <strong>in</strong>ternational <strong>in</strong>put-output tables, such as thosedeveloped by <strong>IDE</strong>-<strong>JETRO</strong>, to separate the domestic contentof an export from the cost of the imported components.This methodology offers a new perspective for tradeanalysts, as it dramatically re-evaluates the importance ofsome economies as “countries of orig<strong>in</strong>”. The result is thatthe absolute <strong>value</strong> of some bilateral trade imbalances isreduced, notably that of Ch<strong>in</strong>a <strong>and</strong> the United States, whileoverall <strong>global</strong> balances rema<strong>in</strong> untouched.6
Vertical specialization, an <strong>in</strong>dicator compiled through<strong>in</strong>put-output tables, allows for an assessment of theforeign content <strong>in</strong>cluded <strong>in</strong> exports <strong>and</strong> hence the tradeoccurr<strong>in</strong>g with<strong>in</strong> <strong>in</strong>ternational production <strong>cha<strong>in</strong>s</strong>. Thelevel <strong>and</strong> growth of vertical specialization do not onlyvary substantially among the <strong>Asia</strong>n economies but alsowith<strong>in</strong> sectors.F<strong>in</strong>ally, Chapter X demonstrates, us<strong>in</strong>g Ch<strong>in</strong>a as anexample, how an export-led development strategy cantrickle down to the rest of the domestic economy. In2010, Ch<strong>in</strong>a became the second-largest economy <strong>in</strong>the world, surpass<strong>in</strong>g Japan <strong>in</strong> terms of nom<strong>in</strong>al grossdomestic product. This was the result of the rapideconomic growth which followed the launch of theReform <strong>and</strong> Open-door policy <strong>in</strong> 1978. The coastalregions of Ch<strong>in</strong>a enjoyed particularly strong growthas a result of preferential development policies heavilyorientated towards exports. However, their successhas led to significant regional disparities. A territorialrebalanc<strong>in</strong>g has been under way s<strong>in</strong>ce the early 2000s,<strong>and</strong> the centre of gravity of development has shiftedto the western regions <strong>and</strong> the North <strong>East</strong>. The nextchallenge for Ch<strong>in</strong>a is to reduce the regional <strong>in</strong>come<strong>in</strong>equalities <strong>and</strong> move from an export-dependenteconomy to a balanced system based more on domesticdem<strong>and</strong>.A glossary <strong>and</strong> a number of technical annexes at the endof the publication provide additional <strong>in</strong>formation on theterms <strong>and</strong> technical po<strong>in</strong>ts developed <strong>in</strong> the differentchapters.7
