本文共9頁 6180字
〖摘要〗我國上市公司具有獨(dú)特的股權(quán)流通性結(jié)構(gòu)：非流通的國有股和法人股占絕對控股地位。這種特性影響股票價(jià)格。本文構(gòu)造了一個(gè)計(jì)量模型，以1997－1999年期間在滬深股票市場上市的389家公司為樣本，分析A股市場股價(jià)與上市公司流通股本規(guī)模和比例等的相關(guān)性。主要計(jì)量結(jié)果包括：股票價(jià)格對公司成長前景(市盈率)和每股收益有非常顯著的正相關(guān)；對流通股本規(guī)模有非常顯著的負(fù)相關(guān)；對流通股比例的負(fù)相關(guān)也比較顯著；對第一大股東國有股還是法人股的正相關(guān)不顯著。本文結(jié)果可為非流通股上市流通政策提供參考。
