【摘要】：隨著滬港通的開通,大陸市場與香港市場的聯(lián)系日益緊密,資金流動更加頻繁,提高了兩地市場的開放水平。但是,我國雙重上市公司的AH股價差一直存在。區(qū)別于其他市場,我國A股價格要高于H股價格,即內(nèi)資股溢價,這被稱為“中國股市之謎”。而滬港通是否會對價差產(chǎn)生影響,要從多個方面綜合衡量。為了對這一現(xiàn)象進行深入地研究,本文首先對研究背景、研究內(nèi)容及方法進行了概述,之后從三個方面對影響AH股價差的因素進行了文獻綜述,接下來介紹了A股市場、H股市場的發(fā)展概況,由于兩地市場制度和交易制度的差異,AH股價差產(chǎn)生。隨后,文章闡述了滬港通的由來、交易概況以及對AH股價差造成的影響。在接下來的章節(jié)中,本文開始進行實證分析。實證部分以86家雙重上市公司2012年3月5日至2016年9月30日的月度交易數(shù)據(jù)作為樣本數(shù)據(jù),選取AH股價差作為被解釋變量,把滬港通設(shè)置為虛擬變量并作為解釋變量,控制變量包括信息不對稱、流動性差異、需求彈性、風(fēng)險偏好、系統(tǒng)風(fēng)險等五個市場因素,公司規(guī)模、投資者結(jié)構(gòu)等兩個公司因素。運用stata軟件將面板數(shù)據(jù)進行回歸,結(jié)果表明滬港通對AH股價差有顯著的正向影響。隨后將股票分為滬港通標的股與非標的股兩組,再分別進行回歸發(fā)現(xiàn),滬港通對其價差也都有顯著的正向影響。這與預(yù)期假設(shè)的符號相反,可能是因為滬港通刺激了A股市場,導(dǎo)致AH股價差擴大。同時,信息不對稱、流動性差異、公司規(guī)模也是影響AH股價差的重要因素。最后,本文根據(jù)實證研究結(jié)果提出了相應(yīng)的政策建議,主要內(nèi)容包括:拓寬投資渠道,促進資本市場開放;加強信息監(jiān)管,健全信息披露制度;加快金融創(chuàng)新,豐富金融產(chǎn)品類別;加強投資教育,培養(yǎng)理性投資觀念;轉(zhuǎn)變投資方式,增加機構(gòu)投資者比例。
[Abstract]:With the opening of the Stock Connect between Shanghai and Hong Kong, the mainland market and the Hong Kong market have become increasingly closely linked, and the capital flows have become more frequent, raising the level of opening up of the two markets. However, the gap in AH stock prices of the dual-listed companies in China has always existed. It is different from other markets. The price of A shares in China is higher than the price of H shares, that is, the premium of domestic shares, which is called "the mystery of the Chinese stock market." whether the Stock Connect of Shanghai and Hong Kong will have an impact on the spread of prices should be comprehensively measured from many aspects. In order to conduct a thorough study of this phenomenon, This paper first summarizes the research background, research contents and methods, then summarizes the factors affecting the AH stock price difference from three aspects, and then introduces the development of A-share market and H-share market. As a result of the difference between the two market systems and the trading system, the difference of AH stock price is produced. Then, the origin of the Stock Connect between Shanghai and Hong Kong, the general situation of the transaction and the influence on the AH stock price difference are described. In the following chapters, The empirical part takes 86 dual-listed companies' monthly transaction data from March 5th 2012 to September 30th 2016 as the sample data, and selects the AH stock price difference as the explained variable. Shanghai Stock Connect is set up as a virtual variable and used as an explanatory variable. The control variables include information asymmetry, liquidity differences, demand elasticity, risk preference, system risk, and company size. Using stata software to regression the panel data, the results show that Stock Connect has a significant positive impact on the AH stock price difference. Then, the stock is divided into two groups: Shanghai Stock Connect shares and non-listed shares. By regression analysis, we find that the Stock Connect also has a significant positive effect on the spread of its price. This is contrary to the expected assumption. This may be because the Stock Connect stimulates the A-share market, resulting in the widening of the AH stock price gap. At the same time, the information is asymmetrical. The difference of liquidity and the size of the company are also the important factors affecting the AH stock price difference. Finally, according to the empirical research results, this paper puts forward the corresponding policy recommendations, including: widening the investment channels, promoting the opening of the capital market; Strengthen information supervision, perfect information disclosure system, accelerate financial innovation, enrich financial product category, strengthen investment education, train rational investment concept, change investment mode and increase the proportion of institutional investors.
