【摘要】:1998年3月,經(jīng)過證監(jiān)會批準,新成立了兩只封閉式基金,監(jiān)管層對機構(gòu)投資者的作用開始加以重視。加入WTO以后,隨著我國經(jīng)濟的增長和金融市場的逐漸開放,證券市場在我國國民經(jīng)濟中的重要作用日益顯現(xiàn)。在此背景下,監(jiān)管層開始從政策層面超常規(guī)支持機構(gòu)投資者的發(fā)展,從而使我國的證券市場形成了包括證券投資基金、保險公司、社保基金和QFII在內(nèi)的諸多機構(gòu)投資者體系,機構(gòu)投資者的總規(guī)模也得到了前所未有的壯大。然而,相對于國外成熟市場而言,我國機構(gòu)投資者因發(fā)展時間較短,存在諸多缺陷。又因不同類型機構(gòu)投資者進入證券市場的時間不同,投資理念和投資策略存在差異,進而導致不同類型機構(gòu)投資者投資偏好以及對股價波動性影響的差異。本文的研究目的是通過實證研究分析不同類型機構(gòu)投資者投資偏好以及對股價的波動性影響是否存在差異,并分析產(chǎn)生差異的原因,提出相關(guān)的政策建議。 本文基于動態(tài)面板數(shù)據(jù)實證研究了證券投資基金、保險公司、社;鸷蚎FII等四種類型的機構(gòu)投資者持股偏好的差異。結(jié)果表明,不同類型機構(gòu)投資者在選股時參照的指標不盡相同,對同一指標參照的標準也不盡相同,不同類型機構(gòu)投資者的持股偏好存在差異。接下來,本文又分別基于面板數(shù)據(jù)和橫截面數(shù)據(jù)實證檢驗了證券投資基金、保險公司、社;鸷蚎FII等四種類型的機構(gòu)投資者持股對股價波動性的影響。結(jié)果表明,,不同類型機構(gòu)投資者持股對股價波動性影響的程度不同。除社保基金外,其它三類機構(gòu)投資者持股的增加均增大了股價的波動性,并且社;饘蓛r波動性的負向影響是微乎其微的。整體而言,機構(gòu)投資者持股并沒有降低股價的波動性。
[Abstract]:In March 1998, with the approval of the CSRC, two new closed-end funds were set up. Regulators began to attach importance to the role of institutional investors. After China's entry into WTO, with the growth of our economy and the gradual opening of the financial market, The important role of the securities market in our national economy is becoming increasingly apparent. In this context, the regulatory level begins to support the development of institutional investors from the policy level, thus making the securities market in our country form including securities investment funds. Many institutional investor systems, such as insurance companies, social security funds and QFII, have also seen unprecedented growth in the total size of institutional investors. However, compared with mature foreign markets, the development of institutional investors in China is relatively short. There are many defects, and because different types of institutional investors enter the securities market at different times, investment ideas and investment strategies are different. The purpose of this study is to analyze the investment preferences of different types of institutional investors and their impact on stock price volatility through empirical research. Is there a difference in response, And analyze the reasons for the differences, and put forward relevant policy recommendations. Based on the dynamic panel data, this paper empirically studies the differences of shareholding preferences among four types of institutional investors, such as securities investment funds, insurance companies, social security funds and QFII. Different types of institutional investors refer to different indexes when selecting stocks, and the criteria of reference to the same index are also different. The preference of different types of institutional investors for holding shares is different. Based on panel data and cross-section data, this paper examines the impact of four types of institutional investors, namely, securities investment funds, insurance companies, social security funds and QFII, on stock price volatility. With the exception of the Social Security Fund, the increase in the shareholdings of the other three types of institutional investors has increased the volatility of the stock price. And the negative impact of social security funds on stock price volatility is minimal. Overall, institutional equity holdings do not reduce volatility.
