美元特权对美国贸易逆差的影响探析

美元特权的形成使贸易逆差成为输出美元的主要途径,并对贸易逆差起到了助长作用,集中表现在美元特权使美国维持着巨额贸易逆差而不受外汇储备短缺的制约和金融危机的威胁,却使其他追求美元储备的国家依靠贸易顺差和过度储蓄来摆脱不利处境,从而从供给和需求两个方面推动了美国贸易逆差的持续扩大。但贸易逆差的继续发展和未来的调整势必会影响美元特权地位的巩固,使世界经济特别是发展中国家的国际经济活动面临极大的风险。     

China and Its Dollar Exchange Rate: A Worldwide Stabilising Influence?1

China is criticised for keeping its dollar exchange rate fairly stable when it has a large trade (saving) surplus. This criticism is misplaced in two ways. First, no predictable link exists between the exchange rate and the trade balance of an international creditor economy. Second, since 1995, the stable yuan/dollar rate has anchored China’s price level and facilitated counter cyclical fiscal policies that have smoothed its high real GDP growth at a remarkable 9 to 11 per cent per year. With its now greater GDP, China displaces Japan as the largest economy in East Asia – but with a much stronger stabilising influence on East Asian neighbours from its higher economic growth and more stable dollar exchange rate. Now, an ever larger China is an essential stabiliser for the world economy – as exemplified by its prompt and effective fiscal response to the global credit crunch of 2008–09. However, cumulating financial distortions – in China and the United States – threaten to undermine China’s growth and its stabilising influence on the rest of the world.     

人民币实际有效汇率调整及其波动率与中美贸易收支

基于1995年1月至2007年9月的月度数据,分析了人民币实际有效汇率与中美贸易收支的关系。结果显示,人民币汇率波动率增加有助于缩小中美贸易收支顺差,人民币汇率升值无论长期或是短期,都不能解决中美双边贸易收支失衡问题。美国经济增长引致的进口需求是中美贸易顺差和我国收入增长的重要原因,在当前经济形势下,要警惕美国经济下滑导致我国的出口下降,进而使我国经济出现"硬着陆"的风险。     

中国对外贸易隐含的碳排放与利益：测算与比较

文章运用环境MRIO模型测算和比较了中国与36个国家（或地区）之间的贸易隐含碳排放余额和增加值贸易余额,全面揭示了贸易所带来的利益与碳排放的关系。主要结论包括：首先,总体来看中国历年贸易隐含碳排放和增加值贸易都为顺差,且呈同步递增趋势,表明中国是碳排放净移入国的同时也是净贸易利益的获得者。其次,中国对26个国家（或地区）的贸易隐含碳排放和增加值贸易呈现双顺差,其中对台湾地区和印尼呈现双逆差,与上述国家（或地区）双边贸易引致的碳排放净流入（或流出）与贸易净利益（或损失）之间呈现互补关系;中国对俄罗斯和印度的增加值贸易顺差而贸易隐含碳排放逆差,使中国获得贸易利益和环境改善的双重收益;对德国等6国的增加值贸易逆差而贸易隐含碳排放顺差,使中国获得贸易损失和环境恶化的双重损失。最后,中国各国（或地区）贸易隐含碳排放余额折算金额后占增加值贸易余额的比重差异较大,总体上中国与发展中国家（或地区）的贸易具有更高的碳排放效率。     

解析美国巨额贸易逆差形成的原因

随着近年来经济全球化进程的加快,美国出现了全球所独有的巨额贸易逆差,并呈现出不断扩大的趋势,分析其贸易逆差形成的原因具有十分重要的现实意义。本文结合当今全球贸易的新特点,重点分析了美国制造业商品贸易的变化,指出美国信息产业等诸多产业已经转移到新兴工业化国家,尤其是亚洲国家。这种全球性的产业转移和技术扩散引致美国制造业国际竞争力下降是其巨额贸易逆差形成和扩大的主要原因。     

Comparative advantage,service trade,and global imbalances

The large current account deficit of the U.S. is the result of a large deficit in the goods balance and a modest surplus in the service balance. The opposite is true for Japan, Germany, and China. Moreover, I document the emergence from the mid-nineties of a strong negative relation between specialization in the export of services and the current account balances of a large sample of OECD and developing countries. Starting from these new stylized facts, I propose in this paper a service hypothesis for global imbalances, a new explanation based on the interplay between the U.S. comparative advantage in services and the asymmetric trade liberalization process in goods trade versus service trade that took place starting in the mid-nineties. First, I use a structural gravity model to show that service trade liberalization lagged behind goods trade liberalization, and I quantify the extent of this asymmetry. Second, I show that a simple two-period model can rationalize the emergence of current account deficits in the presence of such asymmetric liberalization. The key inter-temporal mechanism is the asymmetric timing of trade policies, which affects saving decisions. Finally, I explore the quantitative relevance of this explanation for global imbalances. I introduce trade costs in an otherwise standard 2-sector 2-country international real business cycle model. When fed with the asymmetric trade liberalization path found in the data, the model generates a trade deficit of about 5% of GDP. I conclude that the service hypothesis for global imbalances is quantitatively relevant.     

全球价值链视角下中美增加值贸易与贸易失衡的测算

基于全球价值链视角,采用多区域投入产出模型,利用世界投入产出表数据,测算了1995~2011年中美增加值出口和双边贸易失衡规模。研究表明:相比于传统贸易出口规模,1995年和2011年中国增加值出口分别减少16.06%和24.24%;传统贸易统计方法严重高估中美贸易失衡,同期中美制造业的增加值贸易顺差分别为传统贸易顺差的5%和10%,而中美农业贸易则由传统贸易逆差转变为增加值贸易顺差,中美服务业贸易则由传统贸易顺差转变为增加值贸易逆差;分要素密集度行业来看,中国劳动密集型和资本密集型行业表现为增加值贸易顺差,而知识密集型服务业则为逆差,且逆差规模逐步扩大。     

中国和美国服务业出口竞争力比较分析

本文在界定服务业出口竞争力评价体系的基础上,对中、美两国服务业出口竞争力进行了4个方面的比较分析。通过比较两国服务业净出口额、服务业出口国际市场占有率、服务业贸易竞争优势指数和服务贸易显性比较优势指数4个指标得出:美国在技术密集型的服务业上有极强的出口竞争力,而中国在技术密集型服务业上具有显性比较劣势,并且中国在传统服务业运输和旅游业上的出口竞争力在逐渐减弱,但是中国技术密集型服务业的出口竞争力在增强。最后,本文借助波特的"钻石模型"对中国和美国服务业出口竞争力进行了进一步分析并提出了相应的对策建议。     

中美双边工业品增加值贸易隐含碳福利核算与分配问题研究

现代贸易方式不仅导致贸易利益在全球价值链上进行分配,还带来了贸易隐含污染排放在全球贸易网络中的分布。两国之间的贸易利益分配除了表现为贸易经济福利的分配,还表现为贸易隐含碳福利的分配。本文将贸易增加值分解法结合MRIO模型对2000—2014年中美双边工业品贸易增加值所隐含的碳福利分配及影响机制展开深入分析。研究结果表明:(1)在中美双边工业品增加值贸易隐含碳福利分配中,碳福利逆差在中国,碳福利顺差在美国;(2)中美工业品贸易碳福利级差经历了“先扩大,后收窄”的过程,美国次贷危机之后双边碳福利不平衡状况重新呈现扩大趋势;(3)中国碳排放强度下降、价值链地位提升以及对美进口规模扩大都有助于改善碳福利逆差的局面,但美国对中国不断扩大的中间品和最终品需求以及双边复杂的技术关联结构仍是中国碳福利逆差的主导因素;(4)全球价值链的深化可能将导致对出口国加征关税会通过降低进口消费侧排放的方式恶化加征国的贸易隐含碳福利。本文研究的时间范围同时覆盖中国加入WTO以及美国次贷危机两个重要节点,这对于重新审视中美经贸关系新格局下双边贸易隐含碳福利分配构建了一个新的分析视角,为中美未来贸易谈判以及全球碳排放责任认定提供了一个新的解读方向。     

为什么中国经济会失衡——权力配置失衡下的经济失衡

为什么中国经济会失衡？已有文献分别从收入分配失衡、储蓄过度、资源要要素价格扭曲、计划生育政策所带来的扭曲等方面对此进行了解释。然而,本文认为中国经济失衡的本质在于收入分配的失衡,而决定收入分配失衡的原因在于国内的权力配置失衡和全球的权力配置失衡。国内的权力失衡会导致资源和收入向政府、国有垄断企业、资本所有者、企业主等经济主体的超额分配,使国内收入分配失衡。收入的失衡就会引致中国低消费、高储蓄、高投资和高出口。而美元霸权又导致全球资源向美国配置,并使中国的出口导向战略得以维持,从而加剧了中国的贸易和资本顺差。     

Irrungen und Wirrungen mit der Leistungsbilanzstatistik

In the current crisis the current account surplus and deficit position of single member countries has been considered to be a key indicator of the internal imbalances of the eurozone. German current account surplusses are confronted with current account deficits in the GIIPS countries. But Germany’s current account surplus vis-à-vis these countries has rapidly declined since the outbreak of the global economic and financial crisis mostly caused by the drastic recession in these countries. Furthermore, the near-zero interest rate policy of the ECB has drastically reduced the interest payments from these countries to Germany.     

所有权原则、FDI利得与中美贸易差额

在发达国家大量通过FDI参与国际商业活动的背景下,基于所有权原则的贸易收支统计能够捕捉FDI对贸易收支的影响,从而反映出各国参与国际商业活动的实际利得。根据测算,美国自2000年以来外国直接投资净收益约占其贸易赤字的25%~30%。同时基于所有权统计原则调整后发现,中美贸易顺差根源于FDI,这与现有有关中美贸易不平衡的研究结论大相径庭。     

The Renminbi and Poor‐country Growth

Discussions on how best to exit from global imbalances to create a more balanced world economy have ignored the impact on poor countries of proposals to redress these imbalances. This paper aims at filling that gap. It gauges the degree of renminbi (RMB) undervaluation; presents evidence on RMB undervaluation and China’s GDP growth rate; surveys the role of the real effective exchange rate – both its level and its stability over time – for underpinning growth in developing countries, especially in large dual economies such as China and India; and finally, presents new evidence on growth linkages between China and poor countries for the last two decades and surveys literature on potential displacement effects of RMB appreciation. The analysis allows broad conclusions to be drawn about the potential developing‐country beneficiaries and losers from various renminbi adjustment scenarios in the forthcoming years.     

Development Path of China and India and the Challenges for their Sustainable Growth

The segmentation of global manufacturing and services provided China and subsequently India with a golden opportunity to make full use of their absolute advantage – low‐cost, yet educated labour – to integrate into the world economy within a comparatively shorter period of time than some earlier industrialisers. Though international trade functioned as a vent of surplus in view of the narrowness of their domestic markets at the beginning of their economic catch‐up, the label of export‐led model may not reflect the real picture as imports underwent dramatic increases during their respective growth periods, in particular for China. Foreign direct investment has played a pivotal role in their economic growth and has major presence in international trade and investment in leading sectors of both countries, giving rise to certain special features and weak links for their economic expansion and sustainability of fast economic growth. To maintain more broad‐based, fast and balanced growth, it seems that both countries have to redress sectoral imbalances, encourage technology upgrading and cope with future changes in demographic profiles which constituted a trigger to fast economic growth at the time of their respective economic reform.     

全球失衡背景下中国外部财富分析

外部财富动态为理解全球失衡及其治理问题提供了新标准和新视角。与我国的经常账户持续盈余相对应,我国外部财富由负转正,但是外部财富的价值效应为负。运用外部财富的一个分析框架,对我国外部财富价值效应影响因素的分析表明,我国外部头寸与人民币名义汇率和实际利率存在显著的相互关系,与人民币实际有效汇率和美元实际利率则没有显著的相互关系。外部财富动态分析对于我国内外平衡的宏观经济政策选择具有丰富的政策含义。     

Vehicle currency use in international trade

We explore the major driving forces for currency invoicing in international trade with a simple model and a novel dataset covering 24 countries. We contrasts a “coalescing” effect, where exporters minimize the movements of their prices relative to their competitors', with incentives to hedge macroeconomic volatility and transaction costs. The key determinants of invoice currency choice are industry features and country size, with some role for foreign-exchange bid-ask spreads. The coalescing effect also goes a long way to explaining the well-known dominance of the dollar. Trade flows to the United States are predominantly invoiced in dollar, as foreign exporters face competition with U.S. firms. The use of the dollar in trade flows that do not involve the United States reflects trade in homogeneous products where firms need to keep their price in line with their competitors'.     

当前我国出口行业面临的困境与对策

美国2007年爆发了次贷危机,并导致全球经济放缓,也对我国出口行业产生了消极影响。目前我国外贸出口数量锐减,贸易顺差额明显下降。本文从外需下降、美元贬值、成本上升、贸易环境恶化四个方面分析了当前形势下我国出口行业所面临的困境,并据此提出相应措施予以应对。     

The Foreign Exchange Origins of Japan's Economic Slump and Low Interest Liquidity Trap

Japan's macroeconomic problem has yet to be properly diagnosed. Throughout the 1990s, policy makers could not decide on the proper macro economic measures to combat the country's severe economic slump. We propose a unified explanation, with deep historical roots, of why aggregate private demand failed to recover after Japan's stock and real estate bubbles burst in 1991 and deflationary pressure continues. The problem is not purely ‘made in Japan’. It arises from Japan's unbalanced mercantile relationship with the United States. Starting in the early 1970s, numerous trade disputes between the two countries created tensions that were (temporarily) resolved by the yen going ever higher against the dollar up to 1995. In the last two decades, this persistent pressure for the yen to rise was further aggravated by Japan's large current‐account (saving) surpluses as the counterpart of America's large current account (saving) deficits. The legacy is the expectation that trade and financial tensions will recur so that the yen will be higher 10, 20, or 30 years from now –with Japan's (wholesale) price level forced correspondingly lower and nominal interest rates on yen assets remaining more than four percentage points less than those on dollar assets. This fear of yen appreciation, whose timing is erratic and unpredictable, now inhibits private domestic investment by both Japanese firms and households. Our theory also explains why, in the late 1990s, nominal interest rates on short‐term yen assets were compressed toward zero so as to destroy the normal profit margins of the banking system. In this liquidity trap, the Bank of Japan –whose monetary policy has been quite ‘expansionary’–is powerless to stimulate the flagging economy. To spring the liquidity trap, eliminate deflationary pressure, and restore macro economic balance in Japan, the American and Japanese governments must act jointly to quash the expectation that the yen will be higher in the future than it is today.
