【摘要】:隨著越來越多的國內(nèi)企業(yè)在香港市場發(fā)行H股股票, A+H‖的股票發(fā)行方式愈加普遍,兩地市場的股票價格問題成為許多學(xué)者關(guān)注的重要研究領(lǐng)域。價格發(fā)現(xiàn)和價格信息是金融市場最主要的功能和產(chǎn)品,如何評價兩個市場的價格發(fā)現(xiàn)功能?如何測度兩個市場產(chǎn)生的價格信息的市場份額?這些相關(guān)研究對市場參與者和市場監(jiān)管者具有重要的現(xiàn)實意義。 本文以同時在A股和H股市場上市的股票為研究對象,采用理論和實證研究相結(jié)合的方法,應(yīng)用共同因子模型和市場信息份額模型分析比較了A、H股市場的價格發(fā)現(xiàn)功能。本文首先根據(jù)已有文獻歸納總結(jié)了股票市場價格發(fā)現(xiàn)功能的影響因素理論,并結(jié)合上述理論說明了A、H股市場在發(fā)行上市制度、交易機制和投資者構(gòu)成三方面的差異對其價格發(fā)現(xiàn)功能的影響。然后,從理論上分析了共同因子模型和市場信息份額模型,考察了A、H股的協(xié)整關(guān)系對兩個模型的估計結(jié)果的影響,并對兩個模型進行了變量變換及估計結(jié)果修正。最后,,在考慮了股權(quán)結(jié)構(gòu)、股本流通情況和股本比例等因素之后,選取六家 A+H‖交叉上市公司作為研究樣本,應(yīng)用共同因子模型和市場信息份額模型實證分析了A、H股市場的價格發(fā)現(xiàn)功能。 本文研究發(fā)現(xiàn),共同因子模型的估計結(jié)果受A、H股票價格的協(xié)整關(guān)系的影響,而市場信息份額模型的估計結(jié)果則不受其影響;將調(diào)整后的共同因子模型和市場信息份額模型應(yīng)用到實證研究中,發(fā)現(xiàn)兩個市場的價格發(fā)現(xiàn)貢獻度大致相等,并結(jié)合價格發(fā)現(xiàn)功能影響因素理論及A、H股市場實際情況,從市場微觀結(jié)構(gòu)差異、市場分割、母國效應(yīng)和全球中心說等方面綜合解釋了這一實證結(jié)果。
[Abstract]:As more and more domestic enterprises issue H-shares in the Hong Kong market, the issuance of A-H shares is becoming more and more common. Price discovery and price information are the most important functions and products of the financial market. How to evaluate the price discovery function of the two markets? How to measure the market share of the price information generated by the two markets? These relevant studies have important practical significance for market participants and market regulators. This paper takes the stocks listed in the A-share and H-share markets as the research objects, and adopts the method of combining theoretical and empirical research. The common factor model and market information share model are used to analyze and compare the price discovery function of A and H shares. Combined with the above theories, the paper explains the influence of the differences in the issuing and listing system, the trading mechanism and the investor composition on the price discovery function of the A and H shares market. Then, the common factor model and the market information share model are analyzed theoretically. The influence of co-integration relation of A and H shares on the estimation results of the two models is investigated, and the variables transformation and estimation result correction of the two models are carried out. Finally, after taking into account the equity structure, the circulation of equity capital and the proportion of capital stock, etc. Taking six A-H cross-listed companies as the research samples, the paper empirically analyzes the price discovery function of A and H shares market by using common factor model and market information share model. In this paper, it is found that the estimation results of the common factor model are influenced by the cointegration relationship of AHH stock price, but the estimation results of the market information share model are not affected by the co-integration relationship. Applying the adjusted common factor model and market information share model to the empirical research, it is found that the contribution of price discovery in the two markets is approximately equal, and combined with the theory of influencing factors of price discovery function and the actual situation of A and H shares market, The empirical results are explained comprehensively from market microstructure differences, market segmentation, home country effect and global center theory.
