人民币购买力与中美消费指数的关联性研究

美国政府一直认为中国政府操纵人民币汇率,人民币被认为低估了。本文在中外购买力平价(PPP)的实证研究的基础上,选择三变量模型,对1950年至2010年间人民币汇率及其中美CPI年度数据进行实证检验,结果表明随着人民币汇率市场化程度不断加深,长期来看人民币购买力平价是成立的,并在此基础上对人民币汇率失调情况进行分析。     

对人民币长期升值趋势逆转的研究

近期不明朗的人民币汇率走势又使人民币升值问题成为焦点,本文从购买力平价理论和供求理论出发,对近期经济增速放缓下人民币汇率的走势问题进行了探讨。结论表明,人民币低估的问题已基本被纠正,但在经济增长放缓造成的外需不足、资本外流、刺激货币政策放宽等因素和季节性外币需求高峰的影响下,人民币短期内很有可能改变长期的升值趋势。     

人民币利率平价的实证检验——基于我国“811”汇改后的时间序列分析

本文分别对比了"811"汇改前后人民币利率平价的成立情况,探究我国2015年汇改制度改革的政策有效性。由于我国金融市场尚未达到较高的发达水平,人民币在外汇市场的交易市场化程度较低,因此我们采用非抛补利率平价对人民币的汇率决定机制进行实证检验。结果表明汇改之后利率平价基本成立,而在汇改之前则不成立,说明"811"汇改政策对我国人民币汇率的市场化起到了极大的推动作用,同时在实证分析过程中,我们进一步探究了中美两国利率对汇率的影响机制,实证结果表明,中美利率对汇率的影响存在较为严重的不对称性,其中美国的影响程度是中国的四倍。因此我国虽然汇率制度的市场化程度在"811"之后得到了极大的提升,但与美国等金融市场较为发达的国家比较仍然存在一定的差距。     

人民币购买力平价的协整、对称性与比例性分析

关于人民币购买力平价的研究有助于我们更深入地理解物价和人民币汇率的关系,而国内在这方面的研究并不充分。为此,本文用Johansen方法检验了1987-2010年人民币对美元汇率的购买力平价。实证结果表明,人民币对美元名义汇率、我国价格水平和美国价格水平之间的协整关系显著存在,购买力平价的对称性也成立,但比例性不成立,这与某些发达国家间的汇率特征类似。

从购买力平价角度看人民币汇率

购买力平价是汇率决定的最有影响的理论之一，经常成为各国作为制定经济政策的重要依据。能否依据购买力平价理论来制定人民币汇率政策，已成为目前国内关注的焦点。现有文献对购买力平价的检验结论存在明显的分歧。因此本文通过历年来各大学者的综合观点，总结出了购买力平价对人民币汇率的适用性。     

人民币汇率与中美购买力平价的计量分析

购买力平价理论是现代汇率决定理论的基石之一,本在简要介绍了购买力平价理论的基本思想后,对人民币汇率和中美通货膨胀率的关系进行了直观的数据分析,在此基础上,运用协整技术对中美两国货币的购买力平价关系进行了计量检验,本主要结论是：尽管购买力平价对人民币汇率变化的解释能力较弱,但是,购买力平价在决定人民币汇率中的基础性作用还是存在的。     

汇率变动对东亚四国出口影响的实证分析

本文考察了1997年东亚金融危机以来汇率变动对东亚四国(韩国、泰国、马来西亚和印度尼西亚)出口的影响。通过实证分析发现，韩国和泰国的汇率变动对其各自的出口基本上没有影响；马来西亚的汇率变动对其出口有较明显的影响，汇率的贬值能够有效的刺激其出口的增长；印度尼西亚的回归结果拟和效果不佳，我们并未发现支持汇率变动对其出口有明显影响的证据?

人民币区域化影响力研究——基于动态分布滞后模型的分析

本文在中国对亚洲主要国家的经贸关系和货币合作不断强化的背景下,通过1999-2012年的周度时间序列数据,并以人民币汇改及区域货币合作安排推进为时点,运用动态滞后分布模型分1999.1-2005.7、2005.7-2009.12和2010.1-2012.3三个区间实证分析人民币及其他世界货币对亚洲主要国家货币波动产生的长期影响效应及其变化。通过比较,发现美元对亚洲主要货币的影响下降,澳元影响则显著增强,日元对亚洲货币的影响逐渐衰退,而人民币对亚洲货币的影响较为有限,而这种影响关系主要来源于双边经贸关系的紧密程度,并在此基础上为人民币进一步区域化提出建议。     

Chinese trade price and Yuan's valuation

This paper studies how the major economic events would have affected Chinese yuan's nominal exchange rate against US dollar from 1989 to 2013. The traditional average treatment effect estimation methods cannot be used to consistently estimate yuan's pegged exchange rate. We develop a new estimation strategy by combining a novel panel data method (proposed by Hisao, Ching and Wan) and the purchasing power parity theory. Based on this new estimation strategy, we find that during the period of pegging to US dollar, Chinese yuan were undervalued. Before the 1997 Asian Financial Crisis, the pegged exchange rate regime starting from January 1994 made the yuan undervalued by 2.62%. China's accession to WTO caused yuan undervalued by 36.60%. After the reform of Chinese exchange rate policy in July 2005, the undervaluation of the yuan was reduced to only 0.76%. Yuan was undervalued again by 20.43% because of 2008 China's economy stimulus package. The policy reform in June 2010 made yuan overvalued by 14.40%. We conclude that Chinese fixed exchange rate policy indeed undervalued the yuan, especially after its accession to WTO. The recent reforms of Chinese exchange rate policy made progresses in re‐evaluating the yuan.     

人民币均衡实际汇率:基于Montiel理论模型的研究

以Montiel的理论模型作为选择实际基本经济要素的主要依据,在参考中外学者对均衡汇率研究成果的基础上,结合我国实际情况,运用1980-2006年间相关经济变量数据,构建人民币均衡汇率模型。分析表明:这段时期分别存在人民币低估与高估的问题。人民币均衡汇率应是动态变化的,钉住一篮子货币能较好地反映人民币实际有效汇率的波动。     

Before the fall: were East Asian currencies overvalued?

Two major approaches to identifying the equilibrium exchange rate are implemented. First, the concept of purchasing power parity (PPP) is tested and used to define the equilibrium real exchange rate for the Hong Kong dollar, Indonesian rupiah, Korean won, Malaysian ringgit, Philippine peso, Singapore dollar, New Taiwanese dollar and the Thai baht. The calculated PPP rates are then used to evaluate whether these seven East Asian currencies were overvalued. A variety of econometric techniques and price deflators are used. As of May 1997, the HK$, baht, ringgit and peso were overvalued according to this criterion. The evidence is mixed regarding the Indonesian rupiah and NT$. Second, a monetary model of exchange rates, augmented by a proxy variable for productivity trends, is estimated for five currencies. An overvaluation for the rupiah and baht is indicated, although only in the latter case is the overvaluation substantial (17%). The won, Singapore dollar and especially the NT$ appear undervalued according to these models.     

国际贸易结算货币理论及其对我国的启示

随着多边贸易和国际货币多元化的不断发展,国际贸易结算货币的选择对降低汇率风险和交易成本,提高经济效益显得越来越重要。本文按三个发展阶段对国际贸易结算货币理论进行了述评,在此基础上探讨了目前我国对外贸易结算货币的选择及人民币作为国际贸易结算货币的可能性。认为,当前美元仍应是我国对外贸易首选结算货币,但我国应积极扩大人民币在边境贸易中的计价结算,并努力创造条件促使人民币在远洋贸易中计价结算,以降低国际贸易的汇率风险及促进人民币国际化的发展。     

人民币在“一带一路”货币圈影响力分析——信息溢出效应及其作用渠道

本文运用溢出指数方法,定量测度了人民币与“一带一路”沿线主要货币汇率之间的溢出效应及其动态演化,并采用系统GMM方法,探究人民币汇率净溢出效应的作用渠道。研究发现:近年来人民币与“一带一路”沿线主要货币汇率之间的溢出效应在波动中有所提高,随着“一带一路”倡议的深入实施,人民币汇率净溢出效应逐步提升,在该区域的影响力逐渐增强。在“一带一路”区域内,人民币在亚洲和非洲地区的影响力较强,且对阿联酋迪拉姆和安哥拉宽扎的净溢出效应已超过欧元、英镑和日元等主要国际货币。在净溢出效应的作用渠道方面,“一带一路”国家对中国贸易附加值依存度对其有利,而人民币汇率市场化改革、第三方市场贸易竞争、全球商品价格指数和全球风险指数却对其不利。因此,应加强中国在“一带一路”区域价值链的主导能力和商品竞争能力,加速推动“一带一路”区域内的离岸人民币金融市场建设,加强人民币汇率的区域性风险管理。     

Restarted Exchange Rate Reform Raises New Doubts on RMB Appreciation

The de-pegging of RMB exchange rate from the US dollar does not lead to a substantial change in the exchange rate in the short term. Considering the future regime, if the European financial crisis was not lessened, the Euro and other major currencies would continue to devalue against the U.S dollar and the RMB would probably follow suit.     

Does Euro or Dollar Pegging Impact the Real Exchange Rate? The Case of Oil and Commodity Currencies

The aim of this paper is to investigate the equilibrium exchange rates for commodity and oil currencies as well as the discrepancies of their observed exchange rates to these equilibriums. To this end, first, we estimate a long‐term relationship between the real effective exchange rate and economic fundamentals, including the commodity terms of trade. The estimation relies on panel cointegration techniques and covers annual data from 1980 to 2007. Our results show that real exchange rates co‐move with commodity prices in the long run and respond to oil price somewhat less than to commodity prices. Second, we assess the degree of misalignment of these currencies, as the gap between their observed exchange rate and the estimated equilibrium exchange rate. We show that these misalignments are not significantly related to the exchange rate regimes adopted by the countries, either pegged or floating. However, for pegged currencies, the size of misalignments significantly depends on the anchor currency, either the euro or the dollar. A comparison of misalignments of pegged commodity and oil currencies across different periods confirms these results: during periods of dollar (euro) overvaluation, currencies pegged to the dollar (euro) tend to be overvalued; the reverse being true when the dollar (euro) is undervalued. Consequently, pegged currencies are often driven away from their equilibria by wild fluctuations in the key currencies, on which they are anchored.     

Commodity Price,Carry Trade,and the Volatility and Liquidity of Asian Currencies

This study examines how the volatility and liquidity of 10 Asian exchange rates against the US dollar change with volatilities in commodity price and carry trade over the period of January 2000 to June 2010. We find that uncertainties in commodity markets and carry trades are significantly correlated with the volatilities and the bid‐ask spreads of most Asian currencies. The correlation with carry trade is generally stronger and has been rising over the sample period. While high volatilities in carry trade are associated with high volatilities in many Asian currencies, high volatilities in commodity price do not coincide with excessive volatilities in Asian currencies. This suggests that investors and policymakers should be more concerned with the volatility in carry trade.     

国际货币体系的改革与人民币国际化探析

牙买加体系自1976年创立至今,一直为世界货币基金组织使用,其自身存在着诸多问题,例如美元在现行国际货币体系中获取的权利与承担的义务不对等,整个货币体系的决策机制偏向于美欧等发达国家和地区,对发展中国家不利等问题。因此,对现有国际货币体系实行改革势在必行,应加快推进建立多元化的国际货币体系,增加发展中国家在国际货币体系中的话语权,大力推进人民币的国际化发展进程。
