摘要由于我国的资本市场起步时间比较晚，而且前期政府的干预又比较大，同时又具有特殊的股权分置历史问题,所以股票回购的应用在我国仍然是不够成熟,投资者与公司管理层对回购的认识与理解尚有欠缺。因此,加强对股票回购的理论研究与实证分析,对完善我国股票回购有着积极的推动作用。进入21世纪,国内资本市场上的全流通股占据了绝对的主导地位。因此本文选取我国股权改制后发布回购公告的两家上市公司作为样本,采用事件研究法,来分析股票回购产生的市场效应。结果显示:在国内，上市公司通过回购向市场传达利好消息,对公司的价值修复起到积极的作用；通过分析股权激励型股票样本,表明市场对于上市公司通过回购股份作为激励计划的股份是抱有乐观的态度，即认为通过回购股票的方式配合股权激励有利于公司的发展。同时,在检验超常收益率的过程中,发现有的公司在公告前就已经出现了正的超常收益,表明国内市场上的上市公司存在回购计划提前泄露的情况,市场存在内幕交易和操纵价格的现象。45768
