【摘要】:現(xiàn)階段,我國將引入和實(shí)施QFII制度作為一項(xiàng)資本項(xiàng)目開放的過渡性戰(zhàn)略舉措。從2003年我國引進(jìn)QFII制度到現(xiàn)在,QFII制度已經(jīng)在我國實(shí)施了將近十一年,并已然使其成為推動A股市場發(fā)展的一支重要力量。在此期間,QFII制度的總投資額度經(jīng)歷了五次漸進(jìn)式大擴(kuò)容。本文在對我國QFII發(fā)展現(xiàn)狀進(jìn)行描述的基礎(chǔ)上,以QFII制度在我國發(fā)展中的五次總投資額度放寬事件對A股市場波動影響為切入視角,通過實(shí)證分析,得到QFII制度的漸進(jìn)式發(fā)展對A股市場波動影響程度的結(jié)論,并為推進(jìn)QFII制度的深入發(fā)展和后續(xù)的政策制定實(shí)施提出了相關(guān)建議。 文章采用理論分析和實(shí)證研究相結(jié)合的方法,以國際資本流動理論、現(xiàn)代國際證券投資組合理論和金融自由化理論等經(jīng)濟(jì)金融學(xué)理論為基礎(chǔ),以我國2003年1月4日至2014年3月31日的上證綜合A股指數(shù)收益率序列數(shù)據(jù)為研究對象,基于GARCH模型,采用事件分析法,以QFII制度漸進(jìn)式發(fā)展中的五個(gè)標(biāo)志性事件的發(fā)生日,即:2003年7月9日、2005年7月11日、2007年12月9日、2012年4月3日和2013年7月12日作為時(shí)間節(jié)點(diǎn),將樣本數(shù)據(jù)分成五個(gè)部分,引入五個(gè)虛擬變量和控制變量,實(shí)證研究QFII制度在我國的漸進(jìn)發(fā)展中的不同事件發(fā)生階段對A股市場波動性的影響。 實(shí)證分析認(rèn)為:代表著QFII制度漸進(jìn)式發(fā)展的五個(gè)標(biāo)志性事件對我國A股市場收益率的波動產(chǎn)生了不同程度的影響,由五個(gè)典型事件引發(fā)的政策效應(yīng)與A股收益率波動性之間的相關(guān)性不盡相同。從整體上來看,,如果在不考慮次貸危機(jī)引發(fā)的金融危機(jī)影響的情況下,QFII制度在我國的漸進(jìn)式發(fā)展對我國A股市場波動性的抑制作用在逐漸增強(qiáng);若在考慮金融危機(jī)影響的背景下,QFII順應(yīng)大經(jīng)濟(jì)環(huán)境變遷的撤資行為會加劇我國A股市場收益率的波動。 文章在實(shí)證研究的基礎(chǔ)上,結(jié)合實(shí)證分析所得結(jié)論,對如何健全和完善QFII制度,從而發(fā)揮其促進(jìn)A股市場健康發(fā)展和我國資本市場改革開放的正向效應(yīng)提出了對策建議。
[Abstract]:At present, China will introduce and implement the QFII system as a transitional strategic measure of capital account opening. From 2003 to now, China has introduced the QFII system. QFII system has been implemented in China for nearly 11 years, and has become an important force to promote the development of A-share market. The total investment quota of QFII system has experienced five gradual expansion. This paper describes the current situation of QFII development in China. From the perspective of the impact of five times of relaxation of total investment quota in the development of QFII system on the volatility of A-share market, this paper makes an empirical analysis. The paper draws the conclusion that the gradual development of QFII system affects the volatility of A-share market, and puts forward some suggestions for promoting the further development of QFII system and the subsequent policy making and implementation. Based on the theory of international capital flow, the modern international portfolio theory and the theory of financial liberalization, this paper adopts the method of combining theoretical analysis and empirical research. Based on the data of Shanghai Composite A-share Index return sequence from January 4th 2003 to March 31st 2014, this paper adopts the event analysis method based on GARCH model. The five landmark events in the gradual development of the QFII system, namely, July 9th 2003, July 11th 2005, December 9th 2007. April 3rd 2012 and July 12th 2013 as time nodes, the sample data is divided into five parts, the introduction of five virtual variables and control variables. This paper empirically studies the impact of different events in the gradual development of QFII on the volatility of A-share market. The empirical analysis shows that the five iconic events which represent the gradual development of the QFII system have a different degree of impact on the volatility of the A-share market returns. The policy effect caused by the five typical events and the volatility of A-share yield are not the same. As a whole, if the impact of the financial crisis caused by the subprime mortgage crisis is not considered. The gradual development of QFII system in our country has gradually strengthened the restraining effect on the volatility of A-share market in China. If we consider the influence of the financial crisis, QFII's divestment will aggravate the volatility of the A-share market yield in China. On the basis of empirical research, combined with empirical analysis of the conclusions, how to improve and improve the QFII system. In order to promote the healthy development of A-share market and the positive effect of China's capital market reform and opening up, the countermeasures and suggestions are put forward.
