股票市场与外汇市场的关联性实证研究——基于大陆和香港的比较市场分析

本文主要对大陆和香港的股票市场与外汇市场的关联性进行实证研究,结果表明大陆股市与汇市之间无论从长期还是短期来看都存在紧密的联系。香港股市与汇市长期来看存在协整关系,短期不存在因果关系。最后结合大陆与香港金融市场的特点,给出了一些政策性建议。     

汇率制度改革后中国股市与汇市关系——人民币名义汇率与上证综合指数的实证研究

本文利用协整检验和Granger因果检验的计量方法研究了汇率制度改革后中国股市与汇市的关系。实证结果表明,汇率制度改革后中国股市与汇市存在长期稳定的协整关系,人民币升值是中国股市上扬的单向Granger原因。最后,本文利用国际收支和资本流动理论对这些实证结果作了进一步解释,并提出了相应的政策建议。     

金融危机背景下中国股市和汇市关联效应的实证

运用协整检验、Granger因果检验、向量误差修正模型、方差分解等对金融危机发生前和金融危机发生后中国汇市和股市的关联效应进行实证研究，结果表明无论从短期还是从长期看，金融危机发生前汇率是股价的单向Granger原因，汇率对股价波动的影响较大，股价对汇率的波动影响很小。而在金融危机发生后，汇率和股价存在着双向的因果关系，汇率对股价波动的影响以及股价对汇率波动的影响都较大。金融危机发生后汇市和股市的关联效应明显增强。     

汇率与股价的溢出效应及长期联动性——基于汇改后中国市场的实证研究

随着中国资本市场改革的深化,市场间的互动关系逐步回归市场化关联。本文运用协整检验、Granger因果检验、多元GARCH模型研究了汇率与股价的互动关系。研究结果表明:在长期联动性方面,汇率与股价存在稳定的长期均衡关系;在价格溢出方面,只存在汇率到股价的单向引导关系;波动溢出方面,汇市的波动冲击会影响股市,而股市的波动对汇市无明显影响。进一步的研究中,本文估算了汇率波动对股市开盘价及收盘价的影响大小。     

汇率制度改革后中国地产业与汇市的关系——人民币名义汇率与股市地产指数的实证研究

本文利用协整检验、Granger 因果检验、脉冲响应等计量方法,基于股市与汇市的数据,研究了2005年7月人民币汇率制度改革后地产指数与人民币汇率之间的关系.实证结果表明,人民币汇率与地产指数存在着长期稳定的协整关系,汇率波动是地产指数的 Granger 原因,汇率对地产指数的长短期走势均有显著的影响,人民币升值是地产板块跑赢大盘的重要原因之一.     

汇率波动、外部风险蔓延对我国股市的影响机制研究

基于结构突变的新视角,重新审视人民币汇率、中美股市和利差因素之间的相互影响机理.通过内生变结构协整检验实证发现,样本期内几个金融子市场间的长期均衡关系出现了两次结构突变,汇率与股市间的关系符合流量导向型模型,汇率始终处于主动地位,存在着从汇率到股价的非对称性价格溢出效应;而在市场间联动性上,存在从美国股市到国内股市的非对称性价格溢出效应;全球金融危机是协整关系出现第一次结构突变的直接原因,而这种市场间的相互影响机制则在突变之后逐渐减弱.     

人民币汇率市场化的股市效应研究

汇率作为影响国民经济的重要指标,不仅影响宏观经济的运行,还会作用于资本市场,对上市公司的股票价值、收益率等产生影响。本文从实证方面对汇率和股市的关系进行了分析,对汇率市场化进程下股价指数和汇率两个指标序列进行单位根检验、协整检验以及格兰杰因果检验,以发现我国股市与汇市之间的内在联系。并分行业进行研究,具体分析二者产生联系的原因。     

次贷危机背景下汇市和股市的关系研究

本文通过单位根检验、协整检验、格兰杰因果检验和方差分解等方法对次贷危机爆发前后的汇市和股市关系进行了实证研究。分析结果显示,危机爆发前汇率和股价之间具有协整关系,但是这种均衡关系由于危机的冲击而遭到破坏。从相互联系来看,汇率和股价的因果关系在危机前后都存在。而且,就互相影响的程度而言,危机爆发前汇率和股价之间的波动基本上都来自自身的影响,而在危机爆发后两者受到彼此波动的影响更为显著。基于实证研究结论,文章最后提出了推动金融市场体制改革和汇率市场化进程,加强证券市场规范化建设等政策建议。

人民币汇率与股票价格的联动效应——基于溢出和动态相关视角

本文基于格兰杰因果检验、BEKK模型和DCC模型分别从均值溢出、波动溢出和动态相关三个方面对人民币汇率与股票价格的联动效应进行研究,结果表明:我国汇市与股市之间存在波动的联动效应,汇率的波动会传导至股票市场,加剧股票市场的波动程度,增加股市的风险;同时股市的大幅波动也不可避免地影响人民币汇率的波动趋势.这就要求政府及相关部门决策者,既要重视外汇市场这一风险源头,减缓汇市对股市的波动冲击,也要加强对股市的政策调控,关注股市波动对汇市的影响,实行有效的风险控制和管理.     

Do exchange rate changes have symmetric or asymmetric effects on stock prices?

Several macro variables have been identified as determinants of stock prices and exchange rate is among them. Exchange rate changes can affect different firms differently depending on whether they are export oriented or they use heavily imported inputs. Therefore, the overall effects of exchange rate changes on an aggregate stock price index could be in either direction. Previous research assumed that exchange rate changes have symmetric effects on stock prices. In this paper after introducing nonlinearity into adjustment process and after using Nonlinear ARDL approach to cointegration and error-correction modeling combined with monthly data from Brazil, Canada, Chile, Indonesia, Japan, Korea, Malaysia, Mexico, and the U.K., we show that exchange rate changes have asymmetric effects on stock prices, though the effects are mostly short-run.     

Long-Term Co-Memories and Short-Run Adjustment: Securitized Real Estate and Stock Markets

This study considers whether securitized real estate and stock markets have long-term co-memories and implications for short-term adjustment. Our results offer reasonable support for fractional cointegration (characteristic of a long memory process) between securitized real estate price, stock market price and key macroeconomic factors in some economies. The implication is that where fractional cointegration prevails, securitized real estate and common stocks are substitutable assets over the long run and these assets may not be held together in a portfolio for diversification purpose. Furthermore, short-run analysis indicates that the speed of adjustment towards the long-run equilibrium is faster for fractional integrated vector error correction model (FIVECM) than VECM as the former incorporates a long history of past cointegration residuals. Additional comparisons of the two models’ forecasting accuracy show that incorporating fractional cointegration in a VECM model improves the forecasting performance over conventional VECM models. Our results reinforce the notion that cointegration, fractional cointegration and short-run adjustment dynamics are important in understanding market integration/segmentation.     

Causality and cointegration of stock markets among the United States,Japan and the South China Growth Triangle

This paper explores the causality and cointegration relationships among the stock markets of the United States, Japan and the South China Growth Triangle (SCGT) region. Applying the recently advanced unit root and cointegration techniques that allow for structural breaks over the sample period (October 2, 1992 to June 30, 1997), we find that there exists no cointegration among these markets except for that between Shanghai and Shenzhen. By invoking the Granger causality test and considering the non-synchronous trading problem, we will show that stock price changes in the US have more impact on SCGT markets than do those of Japan. More specifically, price changes in the US can be used to predict those of the Hong Kong and Taiwan markets on next day. Similarly, price changes on the Hong Kong stock market lead the Taiwan market by 1 day. Furthermore, the stock returns of the US and Hong Kong markets are found to be contemporaneous. Finally, there is a significant feedback relationship between the Shanghai and the Shenzhen Stock Exchanges.     

The Impact of Renminbi Appreciation on Stock Prices in China

Since removal of the peg in July 2005, China has entered a new era of a managed floating exchange rate system. Although many observers have raised concerns about the impact of such a policy change on China's trade surplus, less attention has been paid to its effects on financial markets. This paper investigates the impact of recent renminbi appreciation on stock prices in China since removal of the peg, using threshold cointegration and momentum threshold error-correction model (M-TECM). The results clearly illustrate that no short-run causal relation exists, and an asymmetric causal relationship running from the renminbi/U. S. dollar exchange rate to Chinese Shanghai A-share stock prices in the long run is based on M-TECM. Policy and the broader implications of the findings are discussed.     

大陆与台湾股指期货价格发现功能比较研究

本文利用日内15分钟交易数据,对大陆与台湾股指期货的价格发现功能进行了比较,发现沪深300股指期货和现货间存在双向价格引导关系,但在信息传导效率上,期货领先现货,对台湾市场而言,仅存在期货对现货的单向引导关系;期货市场在长期价格发现功能中占主导地位,但台指期货的主导作用要强于沪深300股指期货。文章从投资者结构、合约设计、交易制度等影响因素分析了两岸股指期货价格发现功能的差异,并提出改善大陆股指期货价格发现功能的建议。     

Dollar exchange rate and stock price: evidence from multivariate cointegration and error correction model

In this paper, we investigate existence of long-run equilibrium relationships among the aggregate stock price, industrial production, real exchange rate, interest rate, and inflation in the United States. Applying Johansen's cointegration analysis to monthly data for the 1974:01-1998:12 period, we find that the S&P 500 stock price is positively related to the industrial production but negatively to the real exchange rate, interest rate, and inflation. Analysis of error correction mechanism reveals that the stock price, industrial production, and inflation adjust to correct disequilibrium among the five variables, while variance decompositions indicate that the stock price is driven to a considerable extent by innovations in the interest rate. Structural stability tests show that the parameters of the cointegrating system and the error correction term are stationary.     

中国的股票价格波动及货币政策反应

本文在阐述中国的股票价格波动情况及成因的基础上，分析中国股票价格的信息功能，并对中国的股票价格与各层次货币供应量进行协整和Granger因果检验。结果表明，从总体上看，中国的股票价格在1995年之后，具备一定的信息功能；股票价格与各层次货币供应量之间存在协整、因果关系。由此，货币当局应对股票价格波动做出反应。文章以前瞻性利率规则为基础，运用IS—PC—AP模型，采用GMM法估计出中国包含股票价格因素的货币政策反应函数。     

ON THE DYNAMIC RELATION BETWEEN STOCK PRICES AND EXCHANGE RATES

Abstract In this study we apply recent advances in time-series analysis to examine the intertemporal relation between stock indices and exchange rates for a sample of eight advanced economies. An error correction model (ECM) of the two variables is employed to simultaneously estimate the short-run and long-run dynamics of the variables. The ECM results reveal significant short-run and long-run feedback relations between the two financial markets. Specifically, the results show that an increase in aggregate domestic stock price has a negative short-run effect on domestic currency value. In the long run, however, increases in stock prices have a positive effect on domestic currency value. On the other hand, currency depreciation has a negative short-run and long-run effect on the stock market.
