【摘要】：波動(dòng)溢出效應(yīng)在各個(gè)資本市場(chǎng)中引起了廣大學(xué)者和政府監(jiān)管人員的關(guān)注,眾多國(guó)內(nèi)外文獻(xiàn)針對(duì)各個(gè)金融市場(chǎng)之間的波動(dòng)溢出效應(yīng)作了廣泛的實(shí)證研究,重點(diǎn)探討一個(gè)市場(chǎng)的波動(dòng)對(duì)于另外一個(gè)市場(chǎng)造成的影響以及這個(gè)波動(dòng)是如何來回振蕩。其中,股指期貨市場(chǎng)的波動(dòng)溢出效應(yīng)是最受關(guān)注的研究對(duì)象之一。 學(xué)術(shù)界認(rèn)為,股指期貨的推出對(duì)現(xiàn)貨市場(chǎng)的波動(dòng)性存在兩個(gè)方面(正、反兩個(gè)方面)的影響。從反面來看,股指期貨和股票現(xiàn)貨之間存在著一定的替代效應(yīng),這導(dǎo)致了現(xiàn)貨市場(chǎng)的流動(dòng)性會(huì)因?yàn)楣芍钙谪浀耐瞥龆档�；而從正面的影響來�?推出股指期貨,會(huì)促進(jìn)股票市場(chǎng)的交易,使得股票市場(chǎng)交易變得更加活躍,并且股票市場(chǎng)的價(jià)格波動(dòng)更為合理,套利及套期保值需求會(huì)吸引資金入市,因此可能提高現(xiàn)貨市場(chǎng)流動(dòng)性。從整體上考量,長(zhǎng)期看來,股指期貨的推出會(huì)促進(jìn)現(xiàn)貨市場(chǎng)交易的活躍、穩(wěn)定和有效的價(jià)格發(fā)現(xiàn),進(jìn)而使股市更加健康合理的發(fā)展。而在滬深300股指期貨正式推出前,國(guó)內(nèi)的一些學(xué)者就已經(jīng)利用2006年推出的滬深300股指期貨仿真合約的數(shù)據(jù)資料對(duì)股指期貨市場(chǎng)和現(xiàn)貨市場(chǎng)之間的波動(dòng)溢出性進(jìn)行了一系列的實(shí)證研究。但是由于仿真合約的數(shù)據(jù)畢竟只是模擬交易下的數(shù)據(jù),不具備真實(shí)性,沒有考慮到正式交易中的經(jīng)濟(jì)政策,市場(chǎng)環(huán)境和交易者偏好等相關(guān)因素對(duì)交易的影響,市場(chǎng)交易者不必承擔(dān)相應(yīng)真實(shí)交易情況下帶來的損失(同理,也無法享受真實(shí)交易的利潤(rùn)),因此,基于仿真合約數(shù)據(jù)實(shí)證研究結(jié)論對(duì)現(xiàn)實(shí)的參考意義要遠(yuǎn)遠(yuǎn)小于基于實(shí)盤數(shù)據(jù)的研究結(jié)論。另一方面,滬深300股指期貨剛推出之時(shí),由于時(shí)間尚短,并且市場(chǎng)上的部分投資者對(duì)股指期貨沒有正確充分的認(rèn)識(shí),加上股指期貨市場(chǎng)發(fā)展的不夠成熟,使得市場(chǎng)出現(xiàn)了短期的非正常運(yùn)行。如今,滬深300股指期貨推出已近3年,市場(chǎng)投資者對(duì)股指期貨已有詳細(xì)了解,市場(chǎng)上的非理性行為已經(jīng)基本上消失,其市場(chǎng)規(guī)模也取得了突破性的發(fā)展。另外,股指期貨市場(chǎng)作為股票現(xiàn)貨市場(chǎng)的一個(gè)重要延伸和補(bǔ)充,它對(duì)資本市場(chǎng)的風(fēng)險(xiǎn)管理效果也進(jìn)一步顯現(xiàn)出來。因此,HS300股指期貨的推出對(duì)于股票市場(chǎng)波動(dòng)性的影響以及背后的成因一直是學(xué)術(shù)界和政府決策層討論的熱點(diǎn)問題,也是本文試圖解決的問題。相較于國(guó)外期貨市場(chǎng)成立久遠(yuǎn),國(guó)外市場(chǎng)發(fā)展成熟,我國(guó)滬深300指數(shù)期貨仍然屬于新興商品,但隨著我國(guó)期貨市場(chǎng)的快速成長(zhǎng),期貨交易在整體金融市場(chǎng)中所扮演的角色日漸重要,其中HS300股指期貨帶來的對(duì)于股票市場(chǎng)的影響更為重要。 因此本文將探討在我國(guó)金融市場(chǎng)中,滬深300期貨市場(chǎng)與現(xiàn)貨市場(chǎng)間的波動(dòng)外溢性現(xiàn)象�，F(xiàn)有的文獻(xiàn)中關(guān)于金融市場(chǎng)之間的相關(guān)性研究方法主要有兩類：第一類是研究均值之間的溢出效應(yīng),即考察不同市場(chǎng)間的價(jià)格走勢(shì)的時(shí)序相關(guān)性和條件一階矩間的相互關(guān)系；第二類是研究市場(chǎng)收益率序列之間的波動(dòng)溢出效應(yīng),也就是條件二階矩間的相關(guān)性�！半m然一階條件下變動(dòng)的領(lǐng)先滯后關(guān)系可以對(duì)價(jià)格變化提供預(yù)測(cè)性的信息,但是這種均值關(guān)系卻不一定意味著信息是由領(lǐng)先市場(chǎng)向滯后市場(chǎng)傳遞的,因此更為恰當(dāng)?shù)姆椒ㄊ茄芯績(jī)蓚�(gè)市場(chǎng)間的“波動(dòng)溢出效應(yīng)”(volatility spillover effeet)"(趙留彥、王一鳴,2003)。此外,兩個(gè)序列之間的一階關(guān)系很可能是不真實(shí)的,在深入研究它們之間的高階關(guān)系后,這種一階關(guān)系可能會(huì)消失(Lutkepohl,1993)。所以本文主要研究的重點(diǎn)是兩市場(chǎng)間的波動(dòng)溢出效應(yīng)。通俗地解釋,波動(dòng)溢出效應(yīng)是指一個(gè)市場(chǎng)的波動(dòng)不僅受本身市場(chǎng)波動(dòng)前一期的影響,還要受到其他市場(chǎng)的前期波動(dòng)影響,這種波動(dòng)在市場(chǎng)之間的傳遞效果被稱為波動(dòng)溢出效應(yīng),通過對(duì)波動(dòng)溢出效應(yīng)的研究還可以考察不同市場(chǎng)吸收信息的過程。本研究為了完整檢定期貨交易對(duì)于現(xiàn)貨市場(chǎng)所產(chǎn)生的影響,通過建立合適的EGARCH模型分析股票市場(chǎng)與期貨市場(chǎng)的報(bào)酬率波動(dòng)性,并基于一元EGARCH模型分析兩市場(chǎng)的波動(dòng)性相互影響。在考慮到一元EGARCH的缺陷之后,加入相關(guān)系數(shù)的時(shí)變性特點(diǎn),進(jìn)而引入二元DCC-MVGARCH模型進(jìn)一步分析期貨市場(chǎng)與現(xiàn)貨市場(chǎng)的波動(dòng)溢出效果。本文研究中所選取的數(shù)據(jù)資料是中國(guó)金融期貨交易所的滬深300股指期貨的“當(dāng)月連續(xù)”時(shí)間序列的日交易數(shù)據(jù),時(shí)間從股指期貨正式掛牌交易日2010年4月16日起到2013年2月8日止,剔除非共同交易日的數(shù)據(jù),最終得到676個(gè)數(shù)據(jù)。本文為了研究滬深300股指期貨與現(xiàn)貨市場(chǎng)之間的波動(dòng)溢出效應(yīng),為了研究方便和消除序列的異方差性,對(duì)兩市場(chǎng)的原始價(jià)格取對(duì)數(shù),以避免極端資料影響分析結(jié)果。最終的實(shí)證結(jié)果表明在一元的EGARCH模型下,兩市場(chǎng)均存在非對(duì)稱效應(yīng),在此基礎(chǔ)上的波動(dòng)溢出效應(yīng)擬合結(jié)果不是很理想,因此很可能與一元EGARCH模型的缺陷有關(guān)；緊接著再多元GARCH模型的基礎(chǔ)上發(fā)現(xiàn)兩市場(chǎng)存在波動(dòng)溢出效應(yīng),擬合結(jié)果較好,且兩收益率序列的時(shí)相關(guān)系數(shù)圖表明兩市場(chǎng)的聯(lián)系越來越緊密。
[Abstract]:Volatility spillover effect has attracted the attention of many scholars and government regulators in all capital markets. Many domestic and foreign literatures have made extensive empirical studies on the volatility spillover effects between various financial markets, focusing on the impact of the volatility of a market on the other market and how the volatility is back and forth. Among them, the volatility spillover effect of stock index futures market is one of the most concerned subjects.
The academic circles believe that the introduction of stock index futures has two aspects (positive, two aspects) on the volatility of the spot market. From the negative side, there is a certain substitution effect between stock index futures and stock spot, which leads to the liquidity of the spot market because the stock refers to the introduction of futures, but from the positive effect, The introduction of stock index futures will promote the trading of the stock market, make the trading of the stock market more active, and the price fluctuation of the stock market is more reasonable. The arbitrage and hedging demand will attract the capital into the market, so it may improve the liquidity of the spot market. In the long term, the stock index futures will promote the spot market. The active, stable and effective price discovery of the field trade makes the stock market more healthy and reasonable. And before the Shanghai and Shenzhen 300 stock index futures are officially launched, some domestic scholars have already used the data of the Shanghai and Shenzhen 300 stock index futures simulation contract introduced in 2006 to the volatility spillover between the stock index market and the spot market. A series of empirical studies have been conducted. However, because the data of the simulation contract is only a simulation of the data under the transaction, it does not have the authenticity. It does not take into account the influence of the related factors such as the economic policy, the market environment and the trader's preference on the transaction. The market trader does not have to bear the loss of the corresponding real transaction. (the same reason, also can not enjoy the real transaction profit), therefore, the empirical research conclusion based on the simulation contract data is far less than the real data based research conclusions. On the other hand, the Shanghai and Shenzhen 300 stock index futures have just been introduced, because the time is short, and some investors on the market are not correct to the stock index futures. Fully understanding, and the development of stock index futures market is not mature enough, making the market appear short term abnormal operation. Now, Shanghai and Shenzhen 300 stock index futures have been introduced for nearly 3 years, market investors have a detailed understanding of stock index futures, the irrational behavior in the market has basically disappeared, and its market scale has also made a breakthrough development. In addition, as an important extension and supplement of the stock spot market, the stock index futures market has also shown the effect of risk management on the capital market. Therefore, the impact of the introduction of the HS300 stock index futures on the volatility of the stock market and the causes behind it have always been the hot issues in the academic and government decision-making layers. This paper tries to solve the problem. Compared with the foreign futures market and the mature foreign market, the Shanghai and Shenzhen 300 index futures still belong to the emerging commodities. However, with the rapid growth of China's futures market, the role of futures trading in the overall financial market is becoming increasingly important, in which the HS300 stock index futures bring stock to the stock. The impact of the market is more important.
Therefore, this paper will discuss the volatility spillover phenomenon between the 300 futures market and the spot market in the Chinese financial market. There are two main methods of research on the correlation between the financial markets in the existing literature: the first kind is the study of the spillover effect between the mean value, that is, to examine the temporal correlation of the price trend among different markets. The relationship between the first order moment and the condition first moment; the second kind is the volatility spillover effect between the market returns, that is, the correlation between the two moments of the condition. "Although the leading lag relationship under the first order condition can provide the predictive information for the price change, but this mean relationship does not necessarily mean that the information is From the leading market to the lagging market, the more appropriate method is to study the "volatility spillover effeet" between two markets "(Zhao Liuyan, Wang Yiming, 2003). In addition, the first order relationship between the two sequences is likely to be untrue, and this first order after deep study of the high order relationship between them The relationship may disappear (Lutkepohl, 1993). So the main focus of this paper is the volatility spillover effect between the two markets. A popular explanation, the volatility spillover effect is that the volatility of a market is not only influenced by the previous period of the market volatility, but also influenced by the previous period fluctuations in other markets, which is transmitted between the market. The effect is called volatility spillover effect. Through the study of volatility spillover effect, we can examine the process of absorbing information in different markets. In order to fully examine the impact of futures trading on the spot market, this study is based on the establishment of a suitable EGARCH model to analyze the volatility of the return rate of the stock market and the futures market, and based on the one dollar E. The GARCH model analyzes the volatility interaction of the two market. After considering the defects of the one dollar EGARCH, the time-varying characteristic of the correlation coefficient is added, and then the two element DCC-MVGARCH model is introduced to further analyze the volatility spillover effect of the futures market and the spot market. The data selected in this study are the China Financial Futures Exchange. The daily transaction data of the "month continuous" time series of Shanghai and Shenzhen 300 stock index futures, from April 16, 2010 to February 8, 2013 from the formal listing of stock index futures to February 8, 2013, eliminated the data from the non common trading day, and finally got 676 data. This paper is to study the volatility spillover effect between the Shanghai and Shenzhen 300 stock index futures and the spot market. In order to study and eliminate the heteroscedasticity of the sequence, the logarithm of the original price of the two market is taken to avoid the result of the analysis of the influence of extreme data. The final empirical results show that the two market has asymmetric effect under the one dollar EGARCH model, and the result of the fluctuation spillover effect on this basis is not very ideal, so it is likely to be the same. The defect of the one element EGARCH model is related; on the basis of the multiple GARCH model, it is found that there is a volatility spillover effect in the two market, and the fitting results are better, and the time correlation coefficient diagram of the two yield sequence shows that the connection of the two market is becoming more and more close.
