本文首次在罗尔(Roll)提出的股价非同步性测度模型中引入市场和行业的滞后因素,以沪深两市2002~2011年A股市场1879家上市公司的非平衡面板数据作为研究样本,以股价信息含量为切入点,实证研究了交叉上市与公司价值的关系。结果表明:(1)交叉上市能有效提高公司的股价信息含量;(2)提高公司股价信息含量能增加公司价值,但交叉上市降低了公司价值对股价信息含量的敏感性。从整体上看,交叉上市仍可以通过提高公司股价信息含量进而增加公司价值。

This article firstly makes an improvement of roll's stock price non-synchronicity measure model by adding lagged factors of the market information and industry information. Then we empirically analyzes the relationship between cross-listings and corporation value in terms of stock price informativeness,which based on unbalanced panel data of 1879 companies of Shenzhen Stock Market and Shanghai Stock Market from 2002 to 2011. The results show that cross-listings can notably increase stock price informativeness, and corporation value can be improved by enhancing the stock price in- foxtnativeness, but the sensitivity of corporation value to stock price informativeness can be reduced because of cross-list- ings. The overall result is that cross-listings can improve the corporation value by increasing stock price informativeness.
