汇率制度改革对人民币均衡汇率调整速度的影响

本文首先运用行为均衡汇率模型(BEER)和协整理论,分别测算1994年~2006年和1994年~2005年第2季度的人民币均衡汇率水平,得到相关变量的协整关系式和误差修正模型。笔者通过比较发现:2005年7月21日起,我国实行的新汇率制度可以显著加快汇率回到均衡水平的速度,调整速度从过去每季度调整0.21增加到现在的每季度调整0.35,这说明我国这次汇率制度改革是十分成功的,可以显著加快人民币汇率回到均衡水平的步伐。     

人民币均衡汇率最优决定研究

随着经济全球化和国际贸易、国际结算的迅猛发展,汇率成为经济中一个主要变量,影响着一国的经济,被企业社会所广泛关注。均衡汇率模型的核心是分析基本经济因素变化对均衡汇率的影响,并利用它们之间存在着的系统联系来估计均衡汇率。     

汇率变化与房地产市场的联动趋势——预期及其他因素的实证浅析

研究了2005年汇率改革前后人民币汇率变化对房地产市场的影响。研究发现:预期因素相对其他渠道而言是人民币汇率影响房地产价格的主导因素,而即期和远期汇率牌价不同变化趋势与上海住宅和写字楼指数的不同变化趋势的相关性也充分支持了该观点。人民币升值预期对房地产市场的影响主要归因于房地产商品自身兼具消费品和资本品双重特性以及供求的特殊性。因此,有关部门在考虑和制定相关政策时须充分考虑预期机制的作用。     

1997～2013年人民币均衡汇率失调程度的实证研究

利用行为均衡汇率理论模型对人民币汇率水平进行研究,建立了基于非抵补利率平价理论的行为均衡汇率模型,实证分析了1997～2013年人民币汇率的均衡汇率水平和失调程度;建立误差修正模型分析各变量对于人民币汇率水平的短期影响和人民币汇率系统自身的误差。分析表明：1997年1季度～2013年4季度,人民币实际汇率水平在均衡汇率水平附近波动的幅度不超过±2％。2010年至今,人民币汇率失调程度一直低于±1％,基本达到均衡水平。基于研究结论提出政策建议：一是合理利用政府支出的消费方向调节汇率水平;二是进一步规范与完善资本市场;三是逐步提升汇率的自我修正机制;四是加快推进中国经济转型。     

汇率失调、汇率中性假定和策略汇率

在资本不完全流动的情形下,汇率不仅是体现一国内部经济均衡和外部经济均衡的政策目标,也是一国政府实现其他政治、经济目标的重要政策工具。本文通过考察政府如何以汇率失调为代价,实现政治、经济等战略目标,并以此为基础提出策略汇率的概念,以完善对汇率失调的理论描述和加深对汇率失调内在机制的理解。本文还建立了汇率博弈的政治经济学模型,运用博弈论阐明策略汇率是一个Nash均衡结果。     

人民币行为均衡汇率及错位程度的测算研究:1978-2006

基于行为均衡汇率理论,应用多种计量经济方法对1978-2006年期间人民币实际汇率状况进行的实证分析结果表明:从名义汇率错位情况来看,1995年及以前的名义汇率都是高估的,1996-2005年的名义汇率基本上都是低估的,且低估程度在2000年达到顶点,然后逐渐下降;2005年约低估4.7%,但到2006年,受2005年人民币汇率改革的影响,名义汇率反而高估约0.9%.从实际汇率错位情况来看,1993年及以前的人民币实际有效汇率都是高估的,1994年以后,随着出口的快速增长以及美元的不断贬值,人民币实际有效汇率相对于行为均衡汇率低估程度总体上不断扩大,2005年约低估16.3%;到2006年,受2005年人民币汇率改革的影响,人民币实际有效汇率低估程度有所下降,约低估15.3%.     

The Real Equilibrium South African Rand/US Dollar Exchange Rate: A Comparison of Alternative Measures

This article indicates how different measures of the real exchange rate, i.e., the exchange rate adapted for cost inflation, price inflation and labour costs, influence the equilibrium view and misalignment of the South African rand/US dollar exchange rate. The approach followed is based on the behavioural equilibrium exchange rate approach by Clark and MacDonald (1998), where the exchange rate is influenced by a number of fundamental and transitory factors. The real equilibrium exchange is estimated by using a single equation regression and a number of key explanatory variables. To determine the long-run relationship a Vector Error Correction Mechanism is used.     

The internal and external equilibrium exchange rate of RMB: 1982–2010

This paper estimates fundamental equilibrium exchange rate of RMB based on internal and external balance of China’s economy. The findings indicate that RMB real exchange rate is overvalued in the period of 1982–1991, but the extent of the undervaluation has an enlarging trend since 2004. Then, we put forward a new theory called “Prior Equilibrium Exchange Rate” and apply it to RMB, finding that real effective exchange rate of RMB need to be appreciated about 20% between 2008 and 2010, and the appreciation range of bilateral nominal exchange rate between RMB and the world’s key currencies depends on the objective functions of the government. Policy implication indicates that decision makers need to refer to equilibrium exchange rate which is derived from different theories and to make great efforts to adjust it towards equilibrium level and establish RMB “Prior Equilibrium Exchange Rate.” Meanwhile, policymakers should implement a potential objective interval system of exchange rate appreciation. The appreciation range of bilateral exchange rate of RMB against USD from 2008 to 2010 may be set between 6% to 10%.     

人民币均衡实际汇率的估计与实际汇率错位的测算

基于均衡实际汇率理论 ,本文应用多种经济计量方法实证分析了自 2 0世纪 50年代中期至 2 0 0 0年期间人民币实际汇率状况 ,估计出人民币均衡实际汇率 ,进而测算了实际汇率错位状况。研究结果表明 :在计划经济时期 ,人民币实际汇率长期被高估。改革开放后 ,均衡实际汇率长期处于贬值状况 ,现实的实际汇率长期被低估。在亚洲金融危机期间 (特别是 1 997和 1 998年 ) ,人民币实际汇率出现了明显的高估。 1 999年这种高估状况得到部分缓解 ;2 0 0 0年出现了根本性好转。在现实中 ,1 999年以后中国出口的快速增长也证实了这一结论。     

竞争力平价与人民币均衡汇率研究

传统的汇率决定理论认为，一国货币汇率的衡水平是由购买力平价、利率平价和货币相对供求等决定的。大多数实证研究表明，这些均衡汇率理论只是强调单一因素，同现实相距甚远。本文构建了多因素国际竞争力平价模型，认为均衡实际汇率随着国际竞争力的相对变化而变化，国际竞争力相对提高，该国货币升值，反之则反之。本文利用主成分分析法，从影响人民币汇率的多因素中构造国际竞争力这个指标，实证研究表明人民币实际有效汇率与国际竞争力之间存在协整关系，然后再基于这个协整关系式计算人民币的均衡实际有效汇率，并据以判断人民币汇率偏离均衡水平的程度。     

基于均衡汇率角度的人民币升值问题分析

在人民币不断升值的大背景下,关于人民币升值的合理性及临界点的探讨已成为热门话题。人民币汇率的合理性问题归根到底是实际汇率是否偏离均衡汇率的问题。在考虑中国转型经济特点和对基本经济因素进行分析后,建立了人民币均衡汇率模型,将估计出的均衡汇率与实际有效汇率进行比较分析,确认人民币确实存在一定的低估,但失调程度不大。因此对于人民币升值我们应保持在适度的范围内,而不应屈从于外在压力。在此基础上进一步提出了人民币汇率调整的方法建议。     

Estimating an equilibrium exchange rate for the dollar and other key currencies

In this paper, we adapt the concept of fundamental equilibrium exchange rates ‘FEER’ in a complete model approach. We use it to determine the likely paths of the Dollar and other key currencies. The FEER is the (real) exchange rate that is consistent with internal balance and sustainable external balances. Here we examine the composition of a Dollar adjustment and hence the extent to which a FEER (for the US) depends on factors or rigidities elsewhere in the world, as well as at home. We find, the US still needs to accept an adjustment in her real exchange rate if the increase in her foreign liabilities is to come to an end. However, counterpart adjustments also have to be made in Canada, Mexico, and some Asian economies if this policy is to be successful. We also show that productivity growth differentials may act as a substitute for depreciation, and this provides an explanation for the failure of the dollar to depreciate in the 1990s.     

How frequent a BEER? Assessing the impact of data frequency on real exchange rate misalignment estimation

This article explores the robustness of Behavioural Equilibrium Exchange Rate models, employed to estimate real effective exchange rate misalignments, to the frequency of the underlying data. It compares misalignments stemming from an annual model, estimated since 1980, and a comparable quarterly model, estimated since 1999. The two sets of estimates are similar. Moreover, the in-sample power of quarterly REER misalignments in explaining subsequent REER developments is higher than that of the annual estimates. This article therefore suggests that the “optimal” frequency of a BEER model depends on whether its resulting estimates are employed for research purposes or for policy-making activities.     

人民币汇率管理技术研究

新的人民币汇率形成机制对汇率管理提出了更高的技术要求。人民于汇率管理技术作为一种重要的生产力,为人民币汇率管理提供了重要的操作技巧和技术支持。创新和发展人民币汇率管理技术,有利于进一步提高人民币汇率管理效率和外汇资源配置效率。人民币汇率管理技术的变近大致经历了萌芽阶段、起步阶段、徘徊阶段和快速发展4个时期;人民币汇率管理技术的创新内容包括人民币汇率机制管理技术、弹性管理技术、风险管理技术和信息管理技术等;人民币汇率管理技术的未来发展方向应由“原始型、初级型、封闭型、粗放型、僵化型”向“现代型、市场型、开放型、集约型、创新型”转变。同时,针对人民币汇率管理技术发展中的制约因素,还要注意发展策略的选择,如培育有效的外汇专场主体．加强汇率基础设施建设,营造汇率生态环境,培养金融技术人才等。     

人民币兑美元汇率的局部均衡模型分析

本文利用拓展后的HooperandMorton局部均衡模型,分析了影响中美两国间汇率变动的主要因素。研究发现,在我国确实存在着“高储蓄两难”问题,国内大量的美元资产是导致人民币兑美元汇率升值的主要诱因;而中美两国间相对竞争力的转变与人民币升值压力之间的联系较弱。因此,有步骤地降低外汇储备中美元资产权重有利于缓解目前的人民币升值压力,而加快国内产业升级和技术进步是保持我国国际竞争力的重要途径,适当提升利率更有利于我国经济目前的平稳发展。     

Trade Flows Versus Capital Flows: Are China’s Trade Surpluses Overestimated?

China has received massive foreign capital inflows after experiencing capital flight earlier in the last decade. The present paper offers estimates of capital inflows into China through the misinvoicing of trade after having outlined a model describing how trade prices could be manipulated by firms. In fact, the widely perceived undervalued Yuan has fueled expectations of a future revaluation of the Chinese currency. In a panel gravity modeling framework, we show that, China’s export and import prices for some commodities are sensitive to the non-deliverable forward exchange rate for the RMB in Hong Kong. In light of the evolution of this rate, which has rather systemically reflected anticipated revaluation of the Chinese currency, it is contended that the persistent Chinese trade imbalances may actually camouflage hidden ‘hot money’ inflows. Our findings provide evidence for export over-invoicing and import under-invoicing.     

人民币汇率制度的现实选择--基于中印情况比较的分析

一国所选择的汇率制度,应是既能适应经济发展的要求,又能促进经济的协调运行。印度与中国具有大致相同的有关汇率制度变革需求的现实背景,但是印度货币当局在实施有管理的浮动汇率制度中,保持了卢比汇率的基本稳定,值得我们借鉴。目前,中国具有支撑人民币强势的坚实基础。人民币汇率制度变迁应该根据中国在全球金融经济链条中的民族利益而不是屈从于某些大国政治利益而确定。     

Lost in intervention. The Harrod–Balassa–Samuelson effect on the peseta/dollar real exchange rate (1870–1998)

We have decomposed the peseta/dollar real exchange rate (1870–1998) into its trend and cyclical components and used the former to proxy its time-varying equilibrium. Then, we have compared changes in the equilibrium with changes in the Spanish and the USA productivity differentials to identify years that do not fit with the Harrod–Balassa–Samuelson (HBS) hypothesis. The greatest maladjustment is found in the 1940s and 1950s, decades of strong exchange rate intervention in Spain. Conversely, the link between equilibrium and differentials adjusts to the hypothesis when using the non-intervened peseta/dollar exchange rate on the Tangier black market. These contrasting results back up the idea that exchange rate intervention, so common in developing countries, might explain their scanter evidence in favour of the HBS effect.
