首先，借鉴Perry，Wolfstetter和Zamir（2000）的有关理论，从基于两阶段密封价格投标的竞争性要约收购过程开始，讨论了其中的一些性质，结果表明，同质收购者前提下该过程不但能够获得和基于英式竞价的竞争性要约收购过程相同的期望收益，还能够克服后者存在的一些问题；随后，在异质收购者内生参与条件下就基于英式竞价和密封投标的竞争性要约收购过程进行了比较研究，得到了不同方式下收购结果的特征；最后，针对异质收购者不同知情程度的情况研究了竞争性要约收购方式的选择问题，借鉴Povel和Singh（2004）提出的机制，得到了具备"胡萝卜加大棒"性质的序贯出售过程是这种情况下控股股东的最优选择。
