基于中国主要贸易伙伴双边数据的贸易收支弹性研究

有别于传统的总量分析,利用双边贸易收支模型考量人民币汇率波动与双边贸易收支的关系,能更深刻地揭示汇率波动与我国贸易收支的关系.研究发现,无论是在短期还是在长期,对不同国家而言,不仅双边汇率对双边贸易收支的弹性系数大小不一样,而且双边汇率的波动对贸易收支的影响方向也并不一致,这也说明了采用双边汇率和双边贸易收支样本比总量样本更具有针对性和实践意义.     

Testing J-curve hypothesis and analysing the effect of exchange rate volatility on the balance of trade in India

This study estimates the balance of trade model similar to Rose (1991) to test the J-curve hypothesis and analyse the effect of conditional exchange rate volatility on the balance of trade in India. The model is estimated on quarterly data from 1975:02 to 1996:03 and the exchange rate is measured alternatively in terms of the trade and export weighted real effective exchange rate. The model variables are tied together in a long run equilibrium relationship. The study does not find any evidence for the presence of the J-curve effect in the balance of trade. The study finds the presence of weak ARCH but strong GARCH effects in the exchange rate series. But this exchange rate volatility does not play any significant role in affecting the balance of trade in India.Jel classification: F31, F32, F40, F41I am grateful to Dr. Glenn Otto of the University of New South Wales, Sydney, Australia for his valuable comments and incisive suggestions which helped to improve the paper substantially.

中美贸易失衡与人民币汇率“操纵”——基于汇率与贸易收支关系的实证研究

基于2002年1月至2011年12月的月度数据,运用自回归分布滞后(ARDL)模型,分别从总体和分行业的角度,探讨人民币兑美元实际汇率、汇率波动率与中美贸易收支之间的关系。研究结果表明,无论长期还是短期,人民币汇率水平和汇率波动率对中美两国之间总体和分行业贸易收支差额均不会产生显著影响。该结论意味着无论长期还是短期,中国政府都无法通过汇率操纵来达到扩大中美贸易收支顺差的目的。     

External wealth, the trade balance, and the real exchange rate

We examine the link between the net foreign asset position, the trade balance and the real exchange rate. In particular, we decompose the impact of a country's net foreign asset position (‘external wealth’) on its long-run real exchange rate into two mechanisms: the relation between external wealth and the trade balance; and, holding fixed other determinants, a negative relation between the trade balance and the real exchange rate. We also provide additional evidence that the relative price of nontradables is an important channel linking the trade balance and the real exchange rate.     

人民币升值能改变中国的贸易顺差吗

本文使用非线性平滑转换模型研究了人民币升值对我国贸易顺差的动态影响,研究发现在样本时期内非线性模型能更好地拟合两者的动态关系,在非线性条件下,当期人民币升值将会使贸易顺差增加,前两期人民币升值将会导致当期贸易顺差减少,人民币升值对贸易顺差的影响表现出很强的非线性门限特征。人民币汇率对贸易差额影响的时间路径像是一个"倒J-曲线"。2000年以来人民币汇率虽然一直在发挥着降低贸易顺差的作用,但是,人民币汇率不是贸易顺差形成的主要原因。     

Asymmetric Effects of Exchange Rate Changes and the J‐curve: New Evidence from 61 Malaysia–Thailand Industries

Research on the impact of currency depreciation on the trade balance is now moving in a new direction by incorporating nonlinear dynamic adjustment of the exchange rate and by using a nonlinear approach to error‐correction modeling and cointegration. Using these advances, researchers find not only more evidence of the J‐curve effect, but also new evidence of asymmetric effects of exchange rate changes on the trade balance. We contribute to this line of research by using monthly trade flow data from 61 two‐digit industries that trade between Malaysia and Thailand, and show that not only does currency depreciation have favorable effects on the trade balance of more industries, but the long‐run effects are asymmetric in 26 out of 61 cases. In line with current literature, our nonlinear model performs much better than the linear model when industry level data are used.     

Dynamics of the Relationship Between the Terms of Trade and the Trade Balance in Developing Countries of Asia,Africa and Latin America

The objectives of this study are to examine the relationship between the terms of trade and trade balance to GDP ratios for a large number of developing economies using data on barter terms of trade, real exchange rate and trade balances. The literature on the subject postulates J-curve or S-curve between terms of trade and trade balance and we examine whether there is any evidence of a J-curve or S-curve relationship in time series data over the period 1970–1999. We find that for a few economies in Asia, Africa and Latin America, the existence of a S-curve is supported. However, for a large number of countries, neither a strict J-curve nor S-curve relationship holds.

     

美中贸易收支与人民币汇率关系:实证分析

针对美中贸易收支与人民币汇率问题,经研究发现,汇率变动对贸易收支的影响是值得怀疑的,仅仅依靠人民币汇率变动是无法解决美中贸易逆差问题的。1994—2002年年度数据实证显示,美中贸易收支与人民币汇率(名义或实际汇率)之间没有稳定的关系;1998—2003年月度数据计量表明,美中贸易收支与人民币汇率之间没有长期稳定的协整关系。并且,依据美中两国月度统计数据计量的结论是相一致的。因此,“人民币升值论”或许更多的是基于政治而非经济因素,人民币汇率浮动并不能解决美中贸易逆差问题。     

The Political Economy of Real Exchange Rate Behavior: Theory and Empirical Evidence for Developed and Developing Countries, 1960–2010

Empirical results of testing the PPP hypothesis have constantly shown that relative prices do not converge to the same level, either in the short or the long run. Therefore, the PPP explanation of the real exchange rate does not provide a reasonable measure of competitiveness at the international level. This article puts forth a different approach based on the works of Ricardo, Marx, Harrod and Shaikh. It argues that the real relative unit labor cost is the main factor explaining the long-run behavior of the real exchange rate. The second section of the article explains the theoretical underpinnings of our approach. The third section analyzes the role of the real interest rate differential in explaining real exchange rate misalignments. In the fourth section, we present a graphical analysis of the interrelation among the real effective exchange rate, the real unit labor cost ratio, the short-run real interest rate differential and the trade balance for 16 OECD countries, Taiwan and three developing countries for the period 1960–2010. The fifth section investigates the long-run relationship between the latter three indexes through co-integrating and error correction models using the ARDL–ECM framework. The last section provides our conclusions.     

Asymmetric J-curve: evidence from industry trade between U.S. and U.K.

ABSTRACT

Previous research that assessed the impact of exchange rate changes on the trade balance between the U.S. and U.K. assumed the effects are symmetric. In this paper, we add to the literature on the asymmetric J-curve phenomenon by considering the trade balance of 68 two-digit industries that trade between the two countries. We find short-run asymmetric effects of the real dollar-pound rate in almost all industries. However, short-run asymmetric effects were translated into significant long-run asymmetric effects in 25 industries. Indeed, the asymmetric J-curve hypothesis was supported in 18 industries.     

THE J CURVE: CHINA VERSUS HER TRADING PARTNERS

The short‐run effects of currency depreciation are said to be different from its long‐run effects. In the short run, the trade balance deteriorates and improvement comes after some time; hence, the J‐curve phenomenon. Previous studies that tested the response of the trade balance to exchange rate changes in China employed aggregate trade data and provided mixed results. Indeed, most of them concluded that real depreciation has no long‐run impact on the Chinese trade balance. In this paper, we disaggregate the data by country and using recent advances in time series modelling estimate a trade balance model between China and her 13 major trading partners. We show that real depreciation of the Chinese currency has a favourable impact on her trade balance with a few partners, especially the USA. Not much support is found for the J‐curve hypothesis.     

人民币实际汇率波动对我国贸易收支的影响——基于非对称协整的实证分析

基于1994年1月至2009年4月的数据,采用较新的非对称协整技术,实证考察人民币实际汇率与我国贸易收支之间的变动关系。研究发现,长期中,马歇尔-勒纳条件在我国成立;短期内,J曲线效应在我国存在;人民币汇率与贸易收支间存在非对称协整关系。其中,相对于出现过大的贸易顺差,如果出现贸易赤字,贸易收支恢复长期均衡状态的调整过程较为缓慢。据此认为,相对于出现贸易顺差,当前更应关注外贸不利冲击对我国经济所造成的负面影响。     

Malaysia-Japan Commodity Trade and Asymmetric Effects of Exchange Rate Changes

Asymmetry analysis is a new norm in applied research and the link between the trade balance and the exchange rate is no exception. In this paper we investigate the asymmetric response of the trade balance of each of the 60 industries that trade between Malaysia and Japan. We find short-run asymmetric effects of exchange rate changes on the trade balance of 50 industries (including the two largest industries), short-run adjustment asymmetry in 47 industries, and short-run impact asymmetry in 30 industries. However, short-run asymmetric effects lasted into the long run only in limited number of industries. Results are industry-specific at best.     

人民币汇率、贸易收支与失业率——来自中美两国相关数据的分析

人民币升值是否能够改善美国贸易收支失衡?是否能够带来美国失业率的下降?以此争论为背景,本文采用人民币汇率改革以来的中美相关数据作为分析依据,从马歇尔—勒纳条件及中美贸易产品的相似性两个假设出发,分析了后危机时代人民币汇率变动与美国贸易收支失衡及其失业率的关系,主要得出以下几点结论:(1)中美两国之间贸易产品缺乏汇率—需求弹性,人民币汇率变动对美国进出口数量的影响微乎其微;(2)中美两国贸易产品具有较强的互补性,竞争性则较弱,贸易对就业具有促进作用;(3)人民币升值既不能改善美国的贸易收支失衡,也不能带来美国失业率的下降。     

中国贸易收支和贸易条件的动态关系——对S曲线的适用性检验

本文借鉴BKK(1994)和Abdelhak S.Senhadji(1998)的分析思路,对中国贸易收支和贸易条件的动态关系进行经验分析,结果却表明,用于描述贸易收支和贸易条件动态关系的经验性规律的"S"曲线并不适用于中国。本文认为,导致"S"曲线在中国失效的根本原因在于:中国快速而全面地融入以全球生产网络为载体、以跨国公司为主导的产品内国际分工体系,成为全球生产网络中的"价值增值地"和"出口平台",贸易收支和贸易条件的"相互"作用效应已明显减弱。而在两种商品模型中,贸易条件就等于实际汇率,所以本文的研究结论从另一层面说明:汇率不是中国持续性贸易顺差的原因,试图通过人民币升值不是解决中国贸易顺差的合理之道。     

Black and official exchange rates in Morocco: an analysis of their long-run behaviour and short-run dynamics (1974–1992)

Using Vector Error-Correction (VEC) model estimation on monthly data from Morocco for the period January 1974 to December 1992, this article tests the hypothesis that there is a long-run stable relationship between the official and the black-market exchange rates for US dollars. We also examine the short-run dynamics in the relationship between the two markets. The econometric results indicate that the two exchange rates are cointegrated. Furthermore, we reject weak exogeneity in the case of the official exchange rate, but fail to reject it in the case of the black-market rate. Granger causality tests show that the black-market rate causes the official exchange rate. The results seem to support the efficiency hypothesis, suggesting that participants in the black-market are able to anticipate changes in the official exchange rate. The findings also suggest that Morocco's decision (in January 1993) to introduce only current account convertibility and keep controls on capital accounts was wise.     

全要素生产率、人民币汇率与中国贸易收支——基于跨期最优选择理论的实证研究

文章首先以跨期最优分析框架为基础建立以中国贸易收支为研究对象的理论模型,然后基于中国1999-2009年省际面板数据,运用面板FMOLS估计方法,从全国和地区两个层面对中国全要素生产率、人民币实际汇率与中国贸易收支的关系展开实证分析。研究表明,中国贸易部门内资企业和外资企业的全要素生产率提升均对中国实际贸易余额增长产生了正面影响,其中东部地区的促进作用最为强劲;中国非贸易部门全要素生产率与其实际贸易余额负相关,其中东部和中部地区非贸易部门全要素生产率提升会显著减少该地区的实际贸易差额;人民币实际有效汇率提升对中国实际贸易收支具有显著的负面影响,并按照东部、中部和西部地区依次加重。根据上述分析结果,文章提出了调节中国贸易收支的相关政策建议。     

The role of savings rate in exchange rate and trade imbalance nexus: Cross-countries evidence

Will a higher savings rate improve a country's trade imbalance? Using data for 76 countries for the period 1975–2010, we examine the relationship between trade balance, savings rate, and real exchange rate. To address the potential non-linear effects of the savings rate, we use the panel smooth transition regression (PSTR) model with instrumental variables. Our results indicate that countries with a savings rate above the threshold of 14.8% can improve their trade balance by increasing the savings rate or depreciating their currency. Even though the sample is divided into two groups on the basis of income level, the empirical results vary little, suggesting that our findings are robust to the data separation.     

The U.S. trade imbalance and real exchange rate: An application of the heterogeneous panel cointegration method

The United States economy suffers from persistent trade deficits, arising from the so-called ‘global external imbalance’. Can the depreciation of the US dollar improve this phenomenon? This study for the first time applies the heterogeneous panel cointegration method to examine the long-run relationship between the real exchange rate and bilateral trade balance of the U.S. and her 97 trading partners for the period 1973–2006. Using new annual data, the empirical results indicate that the devaluation of the US dollar deteriorates her bilateral trade balance with 13 trading partners, but improves it with 37 trading partners, especially for China. In the panel cointegrated framework, a long-run negative relationship between the real exchange rate and the bilateral trade balance exists for the U.S.     

CHINA'S EQUILIBRIUM REAL EXCHANGE RATE: A COUNTERFACTUAL ANALYSIS

Abstract.  China's 'equilibrium' real effective exchange rate is explored using an adaptation of the Devarajan-Lewis-Robinson three-good general equilibrium model under a variety of assumptions about the balance of trade. The absence of secondary indices of import and export prices necessitates their construction from trade data. Some undervaluation is suggested in the lead-up to and during the financial crisis, due in part to an extraordinary accumulation of foreign reserves following exchange rate integration in 1994. If, instead, China had run a more typical trade balance prior to the crisis its real effective exchange rate would have been higher by about a tenth.
