77464 Impacts of China’s Accession to the World Trade Organization Elena Ianchovichina and Will Martin This article presents estimates of the impact of China’s accession to the World Trade Organization. China is estimated to be the biggest beneficiary (US$31 billion a year from trade reforms in preparation for accession and additional gains of $10 billion a year from reforms after accession), followed by its major trading partners that also undertake liberalization, including the economies in North America, Western Europe, and Taiwan (China). Accession will boost manufacturing sectors in China, especially textiles and apparel, which will benefit directly from the removal of export quotas. Developing economies competing with China in third markets may suffer small losses. Accession will have important distributional consequences for China, with the wages of skilled and unskilled nonfarm workers rising in real terms and relative to those of farm workers. Possible policy changes, including reductions in barriers to labor mobility and improvements in rural education, could more than offset these negative impacts and facilitate the development of China’s economy. Trade policy reforms such as those flowing from accession to the World Trade Organization (WTO) lead directly to changes in policy instruments, such as tariffs, nontariff barriers, and coverage of trade rules. The main policy concerns, however, are with the impacts on such economic variables as prices; output, employment, and trade volumes; factor returns; and household incomes. This article estimates the impacts on these key economic variables of China’s accession to the WTO as a guide to policy and as a basis for subsequent analysis at the household level.1 It is part of a joint World Bank–Development Research Centre study reported in full in Bhattasali and others (2004).

Because China’s accession was a necessary condition for that of Taiwan and because of the strong trade linkages between the two economies, the impact of Taiwan’s accession to the WTO is also considered.

DOI: 10.1093/wber/lhh030 18:3–27 3 4 THE WORLD BANK ECONOMIC REVIEW, VOL. 18, NO. 1 The obvious instrument for performing this type of analysis is the computable general equilibrium model. Many such models now exist, and a cottage industry has emerged in estimating the impacts of trade reform in China (Gilbert and Wahl 2001).2 The availability of the internationally standard database of the Global Trade Analysis Project (GTAP) has facilitated such modeling and reduced the burden involved in obtaining estimates of basic information, such as trade flows and patterns of production and consumption. What standard models such as GTAP (Hertel 1997; www.gtap.org) do not do, however, is incorporate the nonstandard features of China’s partially reformed economy, where many imports enter duty-free if used in the production of exports and labor market policies result in serious barriers between urban and rural areas. Like Ianchovichina and Martin (2001) and Wang (2003), the analysis here explicitly allows for the duty exemption arrangements that result in close to half of China’s imports entering as duty-free inputs into the production of exports. Recent work by Sicular and Zhao (2004) is drawn on to represent imperfect labor mobility and labor market distortions. This article extends the earlier work reported in Ianchovichina and Martin (2001) by moving to the GTAP version 5 database (Dimaranan and McDougall 2002) based on 1997 data rather than 1995 data; by incorporating improved estimates of protection in agriculture (Huang and others 2004)3 and services (Francois and Spinanger 2004); by using measures of liberalization based on the final, multilateral agreement; by taking into account the restructuring of the automobile sector (Francois and Spinanger 2004); and by simulating the consequences of major labor market reform. This last issue is a particularly critical area for China, and there have been few simulation studies.4 This article first discusses the methodology and then the policy changes associated with China’s WTO accession and the results of the simulation analysis. 2. Among the studies using a general equilibrium approach to quantify the impact of China’s WTO accession are Lejour (2000), Zhai and Li (2000), Li and others (2000), McKibbin and Tang (2000), Ianchovichina and Martin (2001), Walmsley and Hertel (2001), Deutsche Bank (2001), Wang (2002), Zhai and Wang (2002), Walmsley and others (forthcoming), and Ianchovichina and Walmsley (2003). 3. Huang and others (2004) find that nominal rates of protection on important agricultural com- modities (rice, vegetables and fruits, livestock and meat) were negative in 2001 and are likely to remain unchanged in the postaccession period. Consequently, the reduction in agricultural protection is likely to be far less than presented in earlier studies. Nonetheless, greater scope for imports is likely for a range of agricultural products (wheat, oilseeds, sugar, and dairy products) protected by tariffs that are scheduled to be reduced substantially and for products (cotton and feedgrains) for which export subsidies are ruled out. These important findings were not incorporated in earlier studies. 4. The current treatment differs from that in Zhai and Wang (2002), who represent imperfect labor mobility in a single-country model with endogenous urban unemployment but do not differentiate between skilled and unskilled labor and employ a low level of elasticity of labor mobility between rural and urban areas (0.25). The results here are similar to those in Zhai and Wang (2002) in the case of WTO accession with high labor mobility (elasticity of labor mobility is doubled) and fixed urban unemployment (flexible urban wage). Ianchovichina and Martin 5 It then considers some possible complementary policy actions, such as reducing barriers to rural outmigration and expanding access to education. I. METHODOLOGY The standard GTAP model was adjusted to incorporate China’s important export processing arrangements.5 Ianchovichina (2003) documents the approach used and shows that failing to account for China’s duty exemptions in analyzing WTO accession overstates the increase in China’s trade flows by 40 percent and the increase in exports of selected sectors by 90 percent. The adjusted model (GTAP-DD) also incorporates some of China’s key labor market mechanisms and institu- tions that related research has shown may have a major influence on the impacts of WTO accession (Sicular and Zhao 2002, 2004). Export Processing Arrangements Export processing arrangements in China take many forms. Most arrangements allow firms producing goods for export to import intermediate inputs at world prices. These arrangements were incorporated in the GTAP-DD model used in this study by creating two activities for each sector. For sectors covered—or poten- tially covered—by export processing arrangements, one activity is specialized in production for export, and one is specialized in production for the domestic market. This separation is preferable to representations based on a single sector producing differentiated products for domestic and export markets because it allows the two sectors to use different input mixes, and it allows export-oriented activities to use much more import-intensive means of production. This provides a reasonably realistic depiction of China’s trade regime in the 1990s, when duty exemptions were used to facilitate exports while protection in the rest of the economy remained fairly high.6 The tax arrangements for export processing (duty and value-added tax [VAT] exemptions on imported intermediate inputs and VAT refunds on exports) dis- couraged export-oriented firms from using domestic intermediate materials and 5. GTAP is a standard global applied general equilibrium model with perfectly competitive markets and constant returns to scale technology. The model represents consumer demands through a constant difference of elasticities functional form and on the supply side emphasizes the role of intersectoral factor mobility in the determination of sectoral output. Product differentiation between imported and domestic goods and among imports by region of origin allows for two-way trade in each product category, depending on the ease of substitution between products from different regions. Land, capital, skilled and unskilled labor, and in some sectors a natural resource factor are used in production and are fully employed. 6. In a deterministic world, a producer of exports will always take advantage of duty exemptions or rebates unless the administrative costs are excessive, which does not appear to be the case in China. Many studies have either ignored the problem or, as in Lejour (2000), treated duty exemptions as simple reductions in initial tariffs instead of exemptions on imports used specifically in the production of exports. 6 THE WORLD BANK ECONOMIC REVIEW, VOL. 18, NO. 1 selling in the local market. Furthermore, the vast majority of exports were produced using imported intermediates that were either exempt from duties or eligible for refunds on taxes paid.7 China customs data for 2000 show that 60 percent of imports entered duty-free, 41 percentage points of which were imports used for export processing, 13 percent were capital goods, and 6 percent were goods in special categories, such as materials used by research institutes. Rough calculations based on input–output information from the GTAP version 4 database (McDougall and others 1998) and data from China customs suggest that 23 percent of imports were used to produce for the domestic market and only about 3 percent were used to produce ordinary exports.8 Intermediate inputs for domestic and export-oriented activities were initially estimated by allocating them to each sector in proportion to sales in export and domestic markets. However, this yielded unsatisfactory results, with the data- base showing much less use of imported inputs in the export sector than the reported imports of duty-free intermediate inputs for export production obtained from China customs (Li Yan, personal communication). To deal with this, increased use of imported intermediates was allowed for in export activities in accordance with the price changes involved in providing duty exemptions, and the elasticities of substitution between domestic and intermedi- ate goods in the model.9 This more than doubled the import intensity of the exporting activities and reduced that of the domestically oriented activities. Labor Market Policies Perhaps the central labor market issue for the analysis is the barriers to mobility between rural and urban activities. Taking up employment in an urban area is inhibited by the need to obtain an urban residence permit (hukou). In addition, workers tend to be reluctant to permanently cut their ties with the rural sector because it is not generally possible to sell the land to which a rural family has usage rights (Hussain 2004). Many workers move temporarily from rural to urban areas, although restrictions are frequently imposed on such movements, and social welfare benefits (such as health care and schooling for children) 7. The export processing arrangements did not prevent firms producing mainly for the domestic market from exporting. These firms produced exports, known as ‘‘ordinary’’ exports, using mainly domestic inputs and only a small portion of duty- or VAT-paid imported materials (Ianchovichina 2003). 8. According to GTAP version 4, 14 percent of imports were for final consumption and according to China’s customs 40 percent of imports were ordinary imports that were not duty-exempt. This means that about 26 percent were ordinary imports used as intermediates. Also according to GTAP version 4, China’s firms exported an average of 10 percent of their output, implying that only about 3 percent of imports were used for production of ordinary exports. 9. The GTAP version 5 database (Dimaranan and McDougall 2002) is the source for the elasticities of substitution between domestic and composite imported commodities in the Armington produc- tion structure of a sector. The values for these elasticities are shown in column 1 of appendix table A.4 in the World Bank Policy Research Working Paper version of this article, available online at http://econ.worldbank.org/files/26864_wps3053.pdf. Ianchovichina and Martin 7 enjoyed by urban residents are typically not available to temporary migrants. Although it is sometimes possible to overcome these problems by purchasing an urban residence permit, this imposes an additional cost on migrants from rural to urban areas, a group with particularly limited access to capital. As in all countries, rural–urban labor mobility is also inhibited by the sector-specific nature of farmers’ human capital and a reluctance to cut family ties by migra- tion to urban areas. The per capita income of agricultural workers is only about one-third that of urban workers (World Bank 2002). Not all of this difference can be attributed to barriers to mobility between rural and urban areas, however. Urban workers typically have higher skills, work more intensively, and face higher costs of living than rural workers (Sicular and Zhao 2004). To capture the effects of barriers to mobility, the model allows for both imperfect transformation between unskilled workers in agricultural and unskilled nonagricultural employment, and an implicit tax on nonagricultural employment. The imperfect transformation is designed to reflect the substantial differences in the characteristics of unskilled workers in rural and urban areas, and the ability to transform (at a cost) agricultural workers into nonagricultural workers through training, experience, and the creation of nonagricultural jobs in rural areas. The tax is designed to reflect the pure policy-induced barriers between rural and urban workers, such as the requirement for a residence permit in urban areas and the barriers to mobility created by the inability to sell farm land. It is specified as a barrier that raises the cost of labor to urban employers, with urban workers receiving the tax-inclusive wage. The imperfect transformation between agricultural and nonagricultural workers is represented using a constant elasticity of transformation between workers in agriculture and workers in other sectors in the following simple manner: ð1Þ LNF =LF ¼ ðWNF =WF Þ ; where LNF is the number of nonfarm unskilled workers, LF is the number of farm unskilled workers, a is a constant term, WNF and WF are nonfarm and farm wages, and s is the elasticity of transformation. The value of s was set at 1.32, based on Sicular and Zhao’s (2002) estimates of this parameter.10 The tax 10. In a more recent work Sicular and Zhao (2004) estimate the responsiveness of rural labor supply to changes in agricultural returns. They present two ‘‘push’’ elasticities—2.67 for nonagricultural wage employment and 0.24 for nonagricultural nonwage employment. Focusing on the push elasticity for nonagricultural wage employment and testing the sensitivity of the results by replacing the elasticity of 1.32 used in this analysis with 2.67 leaves the aggregate results largely unchanged (appendix table A.7, available online at http://econ.worldbank.org/files/26864_wps3053.pdf). The greater responsiveness of labor movement implied by the larger elasticity of transformation (2.67) translates into better poverty and inequality outcomes because farm wages remain nearly unchanged and an additional 1 million farm workers leave farming. 8 THE WORLD BANK ECONOMIC REVIEW, VOL. 18, NO. 1 reflecting pure policy-induced barriers between rural and urban wages was estimated at 34 percent by Shi (2002). Although there is some level of unem- ployment in China, particularly associated with state enterprise reform and rural–urban migration, much of this unemployment is transitional because of the weakness of the social safety net (Hussain 2004). Given the long-run focus of the analysis here, total employment is treated as exogenous. II. TRADE POLICY REFORMS This section examines the implications of trade policy reforms in China and in its trade partners in the years leading up to accession. Changes in China’s Trade Policies During the 1990s China made substantial progress in reducing the coverage of nontariff barriers, lowering tariffs, and abolishing the trade distortions created by the exchange rate regime. Lardy (2002) estimates that the number of tariff lines subject to quotas and licenses fell from 1,247 in 1992 to 261 in 1999. By 2001, 257 tariff lines were covered by a combination of licenses and quotas and 47 by licenses only, whereas 245 were subject to designated trading and 84 to state trading. Tendering and other registration requirements, primarily for machinery and electrical products, covered an additional 120 tariff lines. By 2001, nontariff barriers covered 664 tariff lines, or less than 10 percent of tariff lines,11 with over a third of these being subject to designated trading, one of the less intrusive forms of quantitative restriction employed in China. Data on nontariff barriers frequency alone may be misleading because of the enormous variations in the importance of tariff lines. To give some indication of the potential importance of nontariff barriers, the import coverage of the key nontariff barriers was calculated using data on nontariff barrier coverage of tariff lines and on import data by tariff line. The import coverage of all nontariff barriers in China fell from 32.5 percent in 1996 (World Bank 1997, p. 15) to 21.6 percent in 2001 (see appendix table A.2). Coverage of import licensing and quotas fell from 18.5 percent in 1996 to 12.8 percent in 2001, and coverage of state trading from 11 to 9.5 percent (table 1). The import coverage of tendering requirements fell particularly rapidly, from 7.4 percent in 1996 to 2.7 percent in 2001. Oil was by far the most important import subject to nontariff barriers, accounting for almost half the value of imports subject to any nontariff barriers (appendix table A.3). Ferrous metals, subject to designated trading arrange- ments, were the second most important category. Imports of oil and oil products accounted for 84 percent of total imports subject to state trading. 11.

Source: For 1996, Lardy (2002); for 2001, Mei Zhen of the Ministry of Foreign Trade and Economic Cooperation during an internship at the World Bank, using data from the WTO. The average protective impact of the complete set of nontariff barriers in China was estimated (very crudely) to be 9.3 percent in the mid-1990s (World Bank 1997), with most of the protective effect arising from licensing and quota- constrained goods. The protective effect of these nontariff barriers has clearly declined since then because of a number of factors, including the progressive phase- out of nontariff barriers, a standstill on new nontariff barriers during the accession process, the general WTO prohibition against nontariff barriers after accession, and a likely reduction in the severity with which many of these measures have been administered. A simple rule of thumb that protection provided by nontariff barriers declines with their import coverage would suggest that their protective impact has fallen to about 5 percent. But given the large margin of uncertainty associated with this measure, the analysis here focuses only on tariff liberalization, implying that the results should be taken as a lower bound to the overall impact of liberalization. The pace of tariff reform in China was also rapid during the 1990s. Although average tariffs were very high in the early 1990s, they fell sharply after 1994 (table 2). A significant tariff reform in October 1997 reduced average tariffs well below 20 percent. Three subsequent reductions at the beginning of 1999, 2000, and 2001 further reduced tariffs on a wide range of items. The progres- sive reductions in tariffs between 1992 and 2001 lowered average tariffs by two- thirds, with larger than average cuts in the manufacturing sector, thereby ensuring that the future reductions in tariffs required under the WTO accession agreement are much smaller than the reductions occurring before accession. Another important feature of the reforms has been a substantial reduction in the dispersion of tariff rates—with the standard deviation falling from 32.1 percent in 1992 to 10 percent in 2001. Examination of weighted average applied tariffs for 1995 and 2001 and after implementation of the final tariff bindings agreed in the accession schedule suggests that substantial merchandise trade liberalization occurred in China 10 THE WORLD BANK ECONOMIC REVIEW, VOL. 18, NO. 1 T A B L E 2 .

Trade data come from COMTRADE. over the period 1995–2001 (table 3). Weighted average tariffs dropped substan- tially for wheat, beverages and tobacco, textiles, apparel, light manufactures, petrochemicals, metals, automobiles, and electronics. Analysis by Huang and others (2004) suggests that some agricultural commodities (such as vegetables and fruits, livestock and meat, and rice) faced negative protection in 1995, generally as a result of restrictions on exports. Protection on these commodities rose (or negative protection fell) over the period 1995–2001. Accession is not expected to lead to a significant fall in protection on most agricultural com- modities after 2001. Import protection is expected to remain unchanged for most commodities except oilseeds, sugar, and dairy products. Protection will continue to fall for all other merchandise commodities, with especially big cuts for processed food, beverages and tobacco, automobiles, electronics, and other manufactures. Francois and Spinanger (2004) conclude that the automobile sector liberalization will be accompanied by massive restruc- turing to realize economies of scale and improve structural efficiency, perhaps increasing productivity by 20 percent during the accession period (2001–07).12 A key element of China’s accession agreement is the abolition of agricultural export subsidies. This required some significant changes. Huang and others (2004) estimate that there was a 32 percent export subsidy on feedgrains and a 10 percent export subsidy on plant-based fibers in 2001 (particularly cotton). 12. Francois and Spinanger base their estimate of the 20 percent productivity increase on the distribution of current plants in China and apply the formula Dln(AC) = CDR . Dln(Q), where AC is average cost, MC is marginal cost, Q is the quantity produced, and CDR is the inverse elasticity of scale, defined as CDR = À(AC À MC)/AC, and varies between 0.125 and 0.135 (the range of values found in engineering studies). Then they calculate an average cost index for the industry. Assuming that the index is 100 at 350,000 units per plant, current plant structure yields a cost index of roughly 120.

Source: Authors’ calculations based on agricultural protection data from Huang and others (2002); manufacturing protection data from GTAP for 1995, from CDS Consulting for 2001, and from China’s WTO final offer for protection after accession; and services protection data from Francois and Spinanger (2004). In addition to China’s barriers on merchandise trade, border measures and domestic regulations on domestic service sectors and trade in these services have reduced the efficiency of services sectors. China has made substantial commitments 12 THE WORLD BANK ECONOMIC REVIEW, VOL. 18, NO. 1 to open its services sectors,13 and critical services such as telecommunications, logistics, and finance are likely to benefit from inward foreign direct investment and rising productivity as they are restructured. Based on work by Francois and Spinanger (2001) reported in Francois and Spinanger (2004), these measures are represented here as barriers to trade in services expressed in ad valorem terms. Following Francois and Spinanger (2004), the impact of accession is represented as halving the barriers to services trade. Efficiency improvements in the services sectors are not modeled because there were no reliable estimates of the likely productivity gains at the time this research was conducted.14 Changes in China’s Trade Partners’ Policies The arrangements for textiles and clothing are a particularly important element of China’s accession. Unlike most other developing economy exporters, China was excluded from the liberalizing elements of the Uruguay Round Agreement on Textiles and Clothing. This means that prior to accession China did not benefit from the integration of textile and clothing products into the General Agreement on Tariffs and Trade (GATT) or from the increases in quota growth rates provided for under this agreement. That placed upward pressure on the prices of these quotas in China, raising the costs of exporters just as an equiva- lent export tax would.15 Under its accession agreement, China benefited imme- diately from the integration of textiles and clothing into the GATT, leading to the abolition of quotas and increases in quota growth rates that have occurred since 1994 (WTO 1994). All quotas are to be phased out by 2005. Importing econo- mies will be allowed to introduce special textile safeguards during the period 2005–07, but these will be effective for only one year at a time. The accession agreement includes a transitional product safeguard mechanism that allows China’s trading partners to take safeguard actions under rules that are more permissive of protection than the usual WTO safeguard rules (Messerlin 2004). These provisions have the potential for introducing a new form of protec- tion against China. This potential danger needs to be weighed against the sub- stantial gains to China from her trading partners being required to follow WTO rules in implementing contingent protection measures against China. For simpli- city, these gains and losses are assumed to cancel each other out. 13. Mattoo (2004) argues that China’s commitments on services were the most comprehensive ever made in the WTO. 14. In a recent paper Mai and others (2003) estimate productivity increases over 10 years of 1.8 percent a year for the strategic manufacturing industries and 2.7 percent a year for the services sectors as reforms take place under WTO accession. 15. These quotas are represented in the analysis as an export tax. In some cases the proceeds of this implicit export tax are redistributed to quota holders, who may be quite different from the producers and exporters of the goods. In other cases the quotas are auctioned, with the quota rents accruing to the government. In either case, the marginal return from additional output of textiles and apparel is net of the quota rent/export tax. Ianchovichina and Martin 13 China’s accession also triggered a liberalization of its partners’ trade policies toward Taiwan (China) with average tariffs estimated to have fallen by almost 1.5 percentage points, from 4.5 percent in 1997 to 3.1 percent in 2001. Taiwan committed to tariff reductions on thousands of industrial and agricultural product lines, a phase-out of tariffs on a number of products as part of the Zero-for-Zero program of the Uruguay Round, and reductions in tariffs on chemical products as part of the Chemical Harmonization program. Tariffs on the vast majority of products related to information technology were also reduced in 2000 and, once WTO accession commitments are implemented, the tariff on electronic products will fall to 0.3 percent (see table 3). Taiwan, China, made horizontal and sector-specific commitments in the following service sectors: business, communication, construction, engineering, distribution, education, environmental, financial, health, social, transport ser- vices, and tourism and recreation. Following Francois and Spinanger (2001), Taiwan’s WTO accession commitments are represented here by a halving of nontariff barriers to trade in services. III. EXPERIMENTAL DESIGN The impact of accession is evaluated here in the dynamic context of the growth and structural change expected in China and its trading partners during the period up to 2007, when almost all of the changes associated with accession will have come into effect. A baseline scenario is constructed under which the economies of the world grow and experience the manifold structural changes associated with economic growth up to 2007 (table 4 and appendix table A.6). The GTAP model includes key elements, such as changes in demand patterns as incomes rise, changes in the industrial structure associated with changes in the stock of capital per worker, and changes in world prices resulting from changes in world supply and demand, that allow the model to capture key changes in the world economy over this period. The baseline broadly replicates World Bank projections for overall growth in each region and uses projections of factor input growth and a residually determined level of total factor productivity growth to ensure consistency between the two. The model considers the effects of the WTO accession agreement signed at the Doha Ministerial Meeting in November 2001 on protection prevailing in 2001. In addition, it separately takes into account the liberalization in China during 1995–2001 because much of the liberalization during the 1990s was influenced by China’s desire to prepare for the type of trade regime needed for WTO accession and to establish the credibility of its commitment to an open economy. These sharp reductions in protection are unlikely to have occurred without the prospect of accession to WTO, and they have been locked in by China’s WTO commitments. Thus results are presented for both the accession period (2001–07) and the entire liberalization period (1995–2007). The analysis starts with 1995 tariff levels because 1995 was a major turning point in the negotiations—the closing of the door on China’s attempt to enter 14 THE WORLD BANK ECONOMIC REVIEW, VOL. 18, NO. 1 T A B L E 4 .

As Long (2000, p. 43) emphasized, China focused more strongly on commercial considerations after 1995 than it had previously—and its trading partners also strongly emphasized the commercial aspects of the negotiations. To capture the implications of WTO accession, 1997 protection data for China in the benchmark data (GTAP version 5) are adjusted to 1995 levels to obtain the initial base.16 For Taiwan, liberalization is considered to have begun in 1997, the year for which tariff data are available in GTAP version 5. Two experiments are conducted to evaluate the impact of WTO accession. The first assesses the impact of the fall in tariffs from 1995 to 2001 levels and the restructuring of the automobile sector accompanying the reductions in tariffs on automobiles and automobile parts during this period. The second assesses the 16. This adjustment was made with ALTERTAX (Malcolm 1998), so that the consistency and the shares in the GTAP database would be preserved. Ianchovichina and Martin 15 impact of the fall in tariffs from 1995 to postaccession (2007) tariff levels, liberalization of the services sectors, continued restructuring of the automobile sector, removal of quotas on China’s clothing and textiles exports, and removal of China’s agricultural export subsidies. The productivity shock designed to capture the restructuring of the automobile sector is proportionate to the fall in tariffs on automobiles in each simulation. The same macroeconomic closure is used for all experiments—full employ- ment,17 perfect mobility of skilled and unskilled workers between nonagricultural sectors, and perfect mobility of unskilled workers within agriculture. Based on the working assumption of little induced change in net international capital flows, trade balances as shares of gross domestic product (GDP) were fixed for China and Taiwan. Although trade balances can be expected to vary during the transition, particularly if there are substantial changes in foreign investment levels, foreign investment levels are not determined within the model.18 Taxes lost because of trade liberalization are assumed to be replaced by a uniform, nondistortionary consumption tax affecting both private and govern- ment final consumption of all goods and services. This hypothetical tax is included to ensure that any adverse impacts of trade reform on government revenues, and hence on the ability to provide income transfers or public services, are allowed for in the analysis of impacts of the reform on households. Because the GTAP version 5 database appears to represent the VAT on domestic production as an output tax, the model generates tax losses from the contraction of such industries as tobacco and alcohol. These inward-oriented industries have higher VAT rates than export-oriented sectors, such as apparel, because exports are exempt from the VAT. When the export-oriented sectors expand, the net impact of WTO accession is a sharp contraction in tax revenues. In reality, such a contraction will not be observed because VATs of the same magnitude are levied on imports. To offset this impact, particularly in the poverty analysis, the consumption tax had to be adjusted downward. This was done by first comput- ing the consumption tax that compensates for the loss in output taxes (this tax as a share of the total replacement tax is equal to the share of the output tax loss in the total tax losses) and then adjusting the consumption tax rate to eliminate the component due to the change in output taxes. To reflect the long-run change in the stance of trade policy, phased in over many years, involved in WTO accession, most of the analysis uses a standard long-run specification, with capital and labor freely mobile between industrial sectors and within agriculture, although there are barriers to labor mobility between rural and urban employment. 17. The fixed employment assumption may understate the costs of accession to some degree. Zhai and Wang (2002), who explore the impact of WTO accession on migration and unemployment, conclude that structural unemployment may rise following China’s WTO accession as farmers move to urban areas. 18. The assumption of fixed trade balance as a share of GDP is required when evaluating welfare impacts using a static trade model such as GTAP. 16 THE WORLD BANK ECONOMIC REVIEW, VOL. 18, NO. 1 IV. ASSESSMENT OF CHINA’S ACCESSION This section assesses the impacts of China’s accession to the WTO on China and its trading partners. Impacts on China The focus here is on the impacts of the trade policy changes remaining after 2001 (detailed results for the period before 2001 are presented in appendix table A.5). A key feature of the period after 2001 concerns the effects of removing the quotas on apparel and textiles imposed on China and other developing economy exporters by major industrial country importers. These quotas are scheduled for abolition in January 2005 for all WTO members. Abolition gives a significant boost to the textile and apparel sectors in China, which had been one of the countries most tightly restricted by the quotas.19 Output in these sectors rises 16 percent and employment 57 percent (table 5). That in turn stimulates the production of plant-based fibers (mainly cotton), which increases by 16 percent. Output and employment in the other agricultural sectors, with the exception of livestock and meat, are expected to fall as unskilled agricultural labor moves into the textile and apparel sectors and unskilled nonfarm real wages rise (table 6). Oilseeds and sugar contract more than other agricultural sectors as a result of falling protection. Tariffs on oilseeds fall from 20 percent to 3 percent, and tariffs on sugar fall from 40 percent to 20 percent. Protection in other agricultural sectors is assumed to remain almost unchanged. The automobile and electronics sectors also expand slightly, creating employment opportunities, particularly for skilled labor.20 Results suggest that approximately 6 million farm workers in China will leave their farm jobs as a result of WTO accession reform after 2001 in pursuit of employment in the nonagricultural sectors.21 For most merchandise goods, real wholesale prices fall as a result of trade liberalization after accession. Retail prices reflect a uniform consumption tax increase of about 1.9 percent levied to compensate for the loss of tariff revenue. For some products, such as beverages and tobacco, automobiles, and sugar, the fall in real retail prices reflects a larger than proportionate drop in protection. Increased demand for nonagricultural labor means higher real nonfarm wages and higher returns to nonagricultural labor relative to agricultural 19. This is a consensus finding supported by Ianchovichina and Martin (2001), Deutsche Bank (2001), Wang (2002), and Ianchovichina and Walmsley (2003). 20. The model underestimates the potential expansion and efficiency increase in the service sectors. With its promise to eliminate over the next few years, most restrictions on foreign entry and ownership, as well as most forms of discrimination against foreign firms (Mattoo 2004), China has set the stage for increases in foreign investment and productivity in these sectors. This in turn could lead to much larger income gains from WTO accession and larger increases in wages of skilled workers than shown here (see Walmsley and others forthcoming). 21. This estimate represents the number of ‘‘effective’’ farm workers likely to migrate from rural to urban areas based on employment data for 2000 from China Statistical Yearbook (NBS 2001, pp. 111–12).

Removal of protection on some agricultural sectors additionally lowers the attractiveness of farming and implies falling returns to farm labor and land. Real farm wages fall 0.7 percent, and the real rental price of land falls 5.5 percent. The decline in farm incomes and the rise in the real retail price of many nonfarm products mean that some farmers may be hurt by WTO accession. Nonfarm wages rise 1.2 percent and skilled labor wages rise 0.8 percent, implying that workers in 18 THE WORLD BANK ECONOMIC REVIEW, VOL. 18, NO. 1 T A B L E 6 .

The liberalization undertaken after 2001 contributes to an increase in China’s share in world exports from 4.4 percent to 7.8 percent on completion of accession. Similarly, China’s share in world import markets rises from 5.8 percent in 2001 to 6.4 percent in 2007. With the removal of textile and apparel quotas, apparel exports lead export expansion with an increase in export volume of about 106 percent, followed by textiles and automobiles. The dramatic fall in protection of beverages and tobacco results in imports more than doubling, followed by increases in imports of food products, textiles, agricultural products, automobile parts, and commercial services. China’s total welfare gain from WTO accession is estimated at $40.6 billion per year (in 1997 dollars), or 2.2 percent of per capita real income (table 7).23 Most of 22. High unemployment due to the restructuring of state-owned-enterprises, privatization, and fierce competition in China imply that WTO accession may dampen the effect on the wages of unskilled workers. By assuming full employment, the model overestimates the increase in wages of workers in the nonfarm sectors, underestimates the fall in the wages of farm workers, and overestimates the increase in total welfare. 23. These estimates are in agreement with findings in Ianchovichina and Martin (2001) and Wang (2002). These are conservative estimates because they do not reflect income increases resulting from trade- and foreign direct investment–induced productivity gains, especially gains associated with liberal- ization of China’s service sectors (Walmsley and others forthcoming). Transaction cost savings from developing institutions compatible with an open and modern market could be very large as well, but were not factored into the analysis. T A B L E 7 .

The remaining reforms will lead to an additional welfare gain of $9.6 billion per year. The largest part of this gain in welfare will come from further merchandise trade liberalization ($4.7 billion, nearly half the $9.6 billion), followed by $2.4 billion (25 percent) from the removal of quotas on textiles and apparel and $1.2 billion (12 percent) from services liberalization. Continuing automobile sector restructur- ing will generate $1.1 billion (11 percent), and the removal of agricultural export subsidies will provide only $275 million (3 percent) in additional benefits. Impacts on China’s Trading Partners Among China’s trading partners the largest absolute gains accrue to North Amer- ica and the Western Europe, with close to half of the gains coming from elimina- tion of the quotas they impose on China’s exports of textiles and clothing—and thus elimination of the efficiency and rent transfers to China. North America, Western Europe, and Japan also gain from China’s cuts in protection, which increase China’s efficiency as an export supplier and its demand for their exports. Taiwan’s welfare gain from its and China’s accession to the WTO is estimated at $3.0 billion per year—the second largest gain relative to the size of the economy after China’s (see table 6). About half of the gain ($1.6 billion) was realized as a result of the liberalization in China and in Taiwan during 1997–2001. Remaining reforms will lead to an estimated real income gain of $1.4 billion a year after 2001. Other newly industrialized economies also benefit from China’s accession. Most of these benefits are associated with trade liberal- ization and removal of quotas on textile and apparel, which translate into gains from terms of trade improvements after 2001. The world as a whole and key developing economies that trade directly with China benefit from China’s accession, but developing economies in Southeast Asia, South Asia, and Latin America that compete with China in third markets may lose from the removal of textile and apparel quotas after 2001. The losses will be largest for Vietnam—an economy that is following in China’s footsteps and has a similar pattern of comparative advantage in labor-intensive products. The welfare loss for Vietnam is estimated as a 1.4 percent drop in per capita income (see table 7). The loss to India is estimated to be considerably smaller as a share of per capita income, at 0.4 percent, whereas the percentage losses to other countries are very small. V. COMPLEMENTARY POLICY REFORMS Although the overall impacts of WTO accession on China’s economy are generally positive, there are some concerns that declines in real returns to farm labor may exacerbate poverty in rural areas. Approaches that deal directly with these problems are more likely to succeed than approaches that attempt to water down China’s trade policy reforms. Two policy tools that lend themselves Ianchovichina and Martin 21 to analysis within the model framework used here are relaxation of the barriers to labor migration from rural to urban areas and skills upgrading for workers in rural areas. Impact of Reducing the Policy Barriers to Labor Mobility Abolishing policy barriers to labor mobility from rural to urban areas—such as residence permits, differences in social insurance, and the inability to sell agri- cultural land—in conjunction with accession leads to a nearly 17 percent increase in real returns to rural workers (see table 6).24 This contrasts sharply with the 0.7 percent reduction in real farm wages for accession without labor market reform. Rents to farmland would decline, with higher farm wages leaving a smaller residual return to farmland. Real urban unskilled wages would decline by an estimated 3.8 percent. Clearly, there would be scope for partial reform of these arrangements that could leave both farm and nonfarm unskilled workers better off than in the absence of labor market reform. These results suggest that this reform would have significant impacts on the number of people leaving their farm jobs for jobs in the nonfarm sectors and on the industry composition of China’s economy. Some 28 million people would leave their farm jobs if the government removed the policy barriers to labor movement from rural to urban areas25—several times the estimated 6 million people who would move as a result of WTO accession reforms alone between 2001 and 2007. The impact on the composition of Chinese industrial output would also be substantial (table 8). This would allow not only apparel produc- tion to expand more but also metals, automobiles, electronics, machinery, other manufactures, and construction, all at the expense of reductions in some agri- cultural sectors. Impact of an Increase in Skill Level A key problem facing most rural workers is their low levels of education. One way to get a sense of the likely impacts of improving access to education is to consider the impact of resultant increases in the skill levels of rural workers on the perform- ance of the Chinese economy. This experiment looks only at the impact of improvements in education on the skills of rural workers. It ignores any potential benefits to rural households from improvements in access to education for their children—such as reductions in school fees—and any changes in the government budget associated with increases in government spending on education.26 24. Zhai and Wang (2002) obtained similar results for a combination of WTO accession and full labor market reform. 25. Because the tax on nonfarm employment of 34 percent represents a bundle of policies that act as a barrier to rural to urban migration, this estimate is representative of the likely impact and could change depending on the policy mix the government adopts. 26. The model does not track education spending as a component of the government budget constraint. T A B L E 8 .

Ianchovichina and Martin 23 An increase in the provision of education that would boost the annual growth rate for skilled labor from 4.15 percent to 5 percent and would lead to a decline in the annual growth rates for unskilled labor from 1.26 percent to 1.1 percent was considered. This was found to have important impacts on the structure of the Chinese economy. An increase in skilled labor leads to a stronger expansion, or a smaller contraction, in the manufacturing sectors that are skilled labor– intensive than does accession with labor market reform but no change in education spending (table 8). Metals, automobiles, electronics, and other manufactures all expand. Although output in some sectors expands, the real wages of skilled workers fall as the supply of skilled workers increases (see table 6) and world prices of the outputs they produce decline. This contrasts with the case of accession alone, which results in an increase in the real wages of skilled workers. How- ever, the real wages of generally much poorer unskilled workers rise with increased education, with the wages of unskilled nonfarm workers rising more than those of unskilled farm workers (see table 6). Of course, those who are able to transfer from agricultural to nonagricultural employment as a result of increased educational opportunities are likely to be substantially better off. Overall, it is clear that increased education spending will generally induce propoor growth and decrease poverty. It certainly has the opportunity to sub- stantially offset the adverse impacts on rural labor of the trade reforms asso- ciated with accession. Finally, increased education boosts the need for migration as demand for unskilled workers increases in large urban areas. An estimated 10 million farm workers are expected to exchange farm jobs for nonfarm ones. The impact on consumer prices is small—with falling prices for farm products and rising prices for manufactured commodities (see table 8). Impact of Labor Market Reform and an Increase in Skill Levels The combination of removing labor market barriers and increasing education spending creates the most favorable scenario for unskilled farm labor, leading to the largest increase in real farm wages (19.4 percent; see table 6). Farm output contracts more than in the case of labor market reform alone, whereas skilled labor–intensive industries such as metals, automobiles, electronics, other manu- factures, and services expand more than in the case of labor market reform alone or increased education spending alone (see table 8). Under this scenario, an estimated 32 million farm workers would leave their farm jobs for jobs in urban areas (see table 6). These results suggest that to generate propoor growth over the next decade, the government should consider both removing policy barriers to labor movement and changing the composition of spending to favor education. Not only would these policies facilitate the transformation of China’s eco- nomy toward services and high-tech manufacturing sectors, but they also have the potential to more than offset any negative impacts of accession on rural wages and incomes. 24 THE WORLD BANK ECONOMIC REVIEW, VOL. 18, NO. 1 VI. CONCLUSION The analysis suggests that the reforming economies and their close trading partners will be the biggest beneficiaries of accession to the WTO. China is undertaking the greatest reform and will gain the most. The North American and Western European economies that abolish their export quotas on textiles and clothing and increase their direct trade with China will gain the most in absolute terms. Taiwan will benefit substantially, both as a consequence of its own liberalization and through strengthened trade links with China. Japan will gain substantially because of increased export opportunities in China and China’s increased competitiveness as a supplier. Other industrializing and indus- trialized economies that are China’s largest trading partners will also be sub- stantial gainers. China’s WTO accession will have a noticeable impact on the level and pattern of global trade. With accession, China is becoming a much bigger player in world markets. Apparel exports will lead China’s export expansion, followed by textiles and automobiles. In addition to being an important source of traded goods, China will become an important destination for other economies’ pro- ducts. Imports of beverages and tobacco will more than double, followed by imports of food products, textiles, agricultural products, automobile parts, and commercial services. The expansion of textiles, light manufactures, petrochem- icals, and equipment exports from Taiwan will be driven almost entirely by demand for these products in China. Accession will have important distributional consequences for China. The wages of skilled workers and unskilled nonfarm workers will rise in real terms and relative to the wages of farm workers. An estimated 6 million people will leave their farm jobs in pursuit of employment in industry and services. Real farm wages and land rental rates will decline. The decline in farm incomes and the rise in the real retail prices of many nonfarm products suggest that some farmers may be hurt by WTO accession after 2001 (see Chen and Ravallion 2004). To help offset these adverse impacts on farmers, the Chinese government might make changes in its labor market policies. Abolition of the hukou system and reform of the labor market more generally would raise farm wages and allow 28 million people to migrate to nonfarm jobs in search of a better life. It would lead to an even bigger expansion of the labor-intensive manufacturing sector. An increase in skill levels would have a positive impact on the structure of the Chinese economy. As the supply of skilled workers increased, the real wages of skilled workers would fall, while the real wages of unskilled workers would rise with increased education spending. Thus, on the income side, increased education spending would induce propoor growth and decrease poverty and inequality. A number of caveats are important. The gains to China and Taiwan are probably understated because tariff aggregation in the GTAP model hides much of the variation in tariffs and the welfare gains from reducing this variation within the product aggregates used in the analyses (Bach and Martin 2001; Ianchovichina and Martin 25 Martin and others forthcoming). When Bach and others (1996) adjusted for this in a partial equilibrium context, gains to China almost doubled. The analysis here assumes flexible wages and full employment. However, trade liberalization and foreign competition may worsen unemployment and put downward pres- sure on the wages of unskilled workers in the short run. Furthermore, although the analysis here improves on Ianchovichina and Martin (2001), with better treatment of the extent of liberalization in agriculture and services and the changes in the automobile sector, there are still areas that have been ignored. One is nontariff barriers in the manufacturing sectors other than the quotas on apparel and textiles. Another is the impact of accession on foreign direct investment and the hard-to-measure efficiency gains in services that are asso- ciated with this increased investment. Foreign direct investment has contributed significantly to China’s economic growth and will play an important role as China continues to reform its economy. WTO accession is likely to increase foreign direct investment in China, as trade liberalization improves returns to investment and the liberal- ization of rules on investment eases financial flows into previously restricted sectors such as services and automobile production. The substantial productiv- ity gaps between local and foreign firms imply that new foreign direct invest- ment will raise productivity.27 Walmsley and others (forthcoming) take into account both the impact of foreign direct investment and increased productivity growth in services. They find that the impacts of accession are far larger than those predicted by earlier studies, including this one, which ignore the potential productivity gains in the services sector and abstracted from capital accumula- tion and foreign investment.
